Okay, riathmus, dude, I wanted to give you a +1 but ended up with a -1... doooh! Is there anything I can do to remove the -1? (Apart from some other member nice enough to make up for my mistake.... which would be great!)

I know, stupid me, shaky fingers and all. Me bad. But why can I not remove the minus 1 again? What if I would do it on purpose, but then rethink my choice?

Sorry TO for the thread hijack, I will stop now... (and if somebody wants to explain to me how to reset my choice, or why it is not possible, send me a PM. I would love to know more, but I feel bad about derailing the thread)

You know that is like the third time that has happened to me this week. So either people really hate me.... lmao or this is a new epidemic! LMAO Dont worry about it though, little bit of negative never hurt anybody.

I also say reduce the bumps... really, unless this is a wreck, rather do NO bumps in the flat areas of the texture... the material "microbumps" of painted metal would be really small even on something as a tank, and a plane actually has a way smoother surface (has to, as the bumps in the surface would increase drag), so just drop it.

I would also look at the specular... too shiny. While a painted civilian plane might have a shiny finish, a military model never has. It would kinda defeat the purpose of the camo. And in this case, it increases the effect of the bumps....

Then for something more subjective... I would use MORE reference images. When I look at your plane, I see you looked at some sci-fi, and maybe at some real planes and vehicles. That is good.

But I see that in the end you ended up with some parts that look rather "unrealistic".... the engines... the weapons in the front. the landing skids.

They are all "okay". I see what they should be , in this sense the fill a purpose. MAYBE they enhance the LOOK of the plane even if being unrealistic (I am not so sure here)...

Still, when your plane should be use more "up close", details like that could stick out too much (also because of the different detail size as explained before). I advise you too look into some theory first, before designing your plane. What I mean:

1. The engines do no look like normal jet-engines. Now, you could say its not a jet engine, its sci-fi tech. Well, it doesn't look very partctical unless its some very weird tech (not streamlined at all). Just for the sake of giving the player something "familiar", if in doubt, go with something realistic, and practical looking.

2. The weapons are not streamlined at all. Both of them. For an example how a gatling cannon has to be integrated into a plane look at an F-14 if you want to go with a fast plane... or the A-10 if you can live with a less streamlined plane.

The rocket launcher (I just guess it is that) has a realistic counterpart, the german Bachem Ba 349 Natter from the last days of WW2... that looked quite similar. After the cap of the launcher was blown off. Because LIKE THAT, no plane could fly at more than maybe 500 km/h..... The Natter had a streamlined cap to get above the plane to be intercepted with speed, and the cap was only blown off shortly before the enemy was engaged.

I am pretty sure you will find more streamlined multiple rocket launchers, and of course, the slower the plane should be, the less such stuff looks out of place. Still, at the moment I do not feel that the weapons look right on your plane... they look like an aftertought tacked unto the plane.

Apart from that, I would maybe distribute the weapons over the plane... having all in the nose looks not very balanced to me from a design perspective.

3. I would rather go with NO landing gear than with the one you sculpted. Really, while it might be good enough for being shown as a small RTS Unit, do you really NEED to sculpt landing gear in this use case? When the unit shown is so small, you could save even more ploygons by just leaving it away.

In general though, a rather good first try. Really, keep it up, and practice. You are on the right tracks

Ok I'm definitely going to reduce the bumps overall. I'm going to try to reduce the bumps that have shown up in my bump maps and leave in only the panel lines. I also need to add detail to those wings and I am not entirely sure what I will add, however.

1): I think it's the intakes that really messed up the feel of the engines. Again, you can comment more on what specifically, but I feel personally that if I improve the intakes for those engines it'll look better.

2): I was going with an A-10 feel for the Gatling guns. It might also be the out of place texturing as well for the Gatling guns? Or should they just be integrated more into the fuselage? As for the nose, I was thinking of a SciFi weapon/enhancement, which is why I didn't quite streamline it.

3): Well I'm not making an RTS, but I can remove them for what I am thinking of doing.

Why do the normal maps have so many bumps? we are talking a plane here... This means it should be smooth and only have bumps where rust or dents might have occurred. The current theme makes it look very unrealistic. I will throw together something here in a bit to show you what I am talking about. Also, I am not sure the theme you are wanting to go with but depending it could very much change how much critique can go on. Right now, I would have a few complaints about the style and model choices, but again the attempt you wanted to aim for matters.

I was just trying to put in the panel lines for the plane. Also I just wanted to add more detail to the overall design. The theme I going for is like a SciFi aircraft that in its age is actually quite outdated. I'm probably going to either remove the wing bump maps or try to improve them. Do you think the fuselage bump map should go as well?

The generalized bump map does not work for such things. Metal isnt "generally" bumpy in this manor and certainly in not big clunks like that. If you had rust regions that might make sense for some odd bump maps in that area and then maybe really bumpy areas where the metal starts to peel away. Normals maps have to make sense for your art to look realistic and more believable. However, if the style you wanted was cartoony than its a different matter all together. In any matter, the goal should be to use realistic values and modify them based off of the style you wish to go for. We do the same thing with human anatomy and character models. You dont want to just place some randomized anatomy without any form or function because you think it will "look good", to the human eye it will look off and people will judge the model/character based off of this impression. However, when you work on something that has a purpose or a reason and follows the form of an object the brain will fill in the puzzle pieces automatically and the viewer will not skip a beat or question the choices. To get an idea of what metal looks like when rusted check these out:

http://www.mayang.com/textures/Metal/html/Metal%20Objects/index.html

Notice the smoothness of the non rusted areas. Painted metal has a VERY small bump map to it, but you shouldnt see this from a far away profile. However, when you get close you could.

http://developer.download.nvidia.com/whitepapers/2008/normalmapdxt_id_files/09_metal.png

Is another example of a normal map that might be found on the metal. notice most of the texture is flat and without variance. In the "dented" areas you have some slight bends and curves but they are rather large and not spread across the entire surface. Even the dents where something hit the metal are deep, precise, and with purpose. Try to aim for this in your bump map and you will really have something. If you are just doing this to learn, you could provide the .fbx here and I wouldnt mind throwing together something for you to look at. Assuming the UV's are not horrible :P I dont like to waste time fixing uv's, but thats just me.

I'm going to try to keep my panel lines but get rid of the other bumps.

Nice.

What do you specifically like? I would love to hear what you thought really works.

The project I'm making this for is going to be a serialized set of episodes that will have mostly cinematic content but will also be interactive/have playable sections. It's more of a side project/hobby/thing, so I'm trying to make things that are relatively good. I'm not a 3d artist by trade, truth be told. I'm actually a programmer (CS guy lol), but I've been doing 3d art on and off for some time, and have made some progress. Like I said, I'm interested in learning.

I will probably post back with more photos of my improved model.

Is it also ok if I post to this thread periodically for other art work I will ultimately make? Or would it be preferred to start a new thread altogether? Thanks for your help guys, it's really very helpful to know what I should improve.

This is a personal opinion, but don't add details just for the sake of adding details. If something looks to bland, and you don't want it to look "realistic", sure, add things (I know this is what many people understand as "steampunkifying things"... I do not agree really, but then again, that is my opinion).

But if you want it to look realistic, or at least be a little bit based on reality, check out pics of real planes first. And there you will quickly find out that wings seldom have much on them besides some slight seams, and in case of old planes, maybe bolts, the odd engine if the plane has the engines mounted on the wings, and then maybe the wheels if they fold into the wing / are fixed to the wing.

Other than that, the wing is pretty much bare. BECAUSE the wings main function is to provide lift, which gets kinda hard to do if you add stuff that will disturb the airflow!

Some things that you COULD find on a realistic wing are the flaps n' stuff used for steering (you could just add something to the normal map if you do not want to make it movable), lights integrated into the front or the ailerons, ailerons (though you already have them on your wing), and the casings for the hydraulics that move the flaps (see https://en.wikipedia.org/wiki/Flap_%28aeronautics%29#/media/File:Easyjet_a319_wing_g-ezav_arp.jpg and https://upload.wikimedia.org/wikipedia/commons/2/2b/Wing.slat.600pix.jpg).


1): I think it's the intakes that really messed up the feel of the engines. Again, you can comment more on what specifically, but I feel personally that if I improve the intakes for those engines it'll look better.

Mmmm.... now I might be nitpicking, but these engines are just not aerodynamic enough for a plane. Don't get me wrong, given you are not too concerned about "realism", a non-aerodynamic engine is quite fine. Then I would just go with the rule of cool. Change the intakes, and see if it looks cooler.

Given you do care about realism, first think about making the engine round. That hard edges are bound to generate a hell of a lot of turbulences. Airplanes moved away from rectancular, boxy structures before they were even over 300 km/h fast... given you have a hell of an engine and don't care about the fuel usage, as well as wear and tear, that would still not be so much of a problem at higher speeds (might make the plane quite hard to control though).

Still, realistically, it does not make sense to make rectangular engines for a plane...


2): I was going with an A-10 feel for the Gatling guns. It might also be the out of place texturing as well for the Gatling guns? Or should they just be integrated more into the fuselage? As for the nose, I was thinking of a SciFi weapon/enhancement, which is why I didn't quite streamline it.

Again, IMO.... I would integrate those gatling guns more into the fuselage. This setup might be fine for a helicopter type of system, which doesn't need to generate lift the way a plane does (where the fuselage actually also add to the general lift, thus also needs to be streamlined), and goes at sub 500 km/h... even then, modern choppers tend to integrate their cannons into nose turrets, most probably to reduce drag and save fuel, as well as (I guess) make the radar signature smaller.

Then the whole gun assambly looks rather "short"... always remember, the mechanism that actually fires the projectiles through the rotating barrels needs to be inline with the barrel assembly.... in a cannon that is outside of the fuselage that means the full length of the cannon is visible... in your case, given the visible diameter of the barrels, that might be a short barreled gatling grenade launcher, or at best some VERY short barreled howitzer.

Something with both very low muzzle velocity (unless the round has an EXTREME amount of propellant in the casing), and a horrible accuray (which tends to be linked to the length of the barrel).

There are examples like that, airplane cannons that have explicitely been built to fit the largest possible caliber into the lightest and shortest possible weapon... see the german 30mm mk 108 (http://www.warbirdsresourcegroup.org/LRG/mk108.html)... which exhibited just the chracteristics mentioned, low muzzle velocity and accuray, with a much higher caliber and more useful HE round as its main advantage over 20mm weapons of similar weight.

I wouldn't say the texture is out of place... I do dislike the "WH40k" way of painting metal parts as "chrome metal", like it is done by many famous tabletop miniature painters. Its a try to get more color into otherwise dull military colors (which is just camo, realisticly), but to me it is wrong on so many levels. I prefer dark grey or black for the few parts that are not being painted with camo, to represent blued steel.

But these personal opinion left aside, I don't see anything particularly wrong with your choice of color.

One thing you COULD do do enhance the look of your model is to bake ambient occlusion to your model. There are many tools that can do the job for you, you basically just want to calculate an AO map or curvature map, and then blend this over the texture in Photoshop. This makes the crevices darker (and in case of the curvature map, accents the edges of the model).

IMO one of the best and cheapest ways the enhance a models look if you happen to find a tool that can bake the map automatically for you (Crazy Bump might do it, XNormals does it, a lot of other tools are available that do it. Blender might also work, don't know.)


3): Well I'm not making an RTS, but I can remove them for what I am thinking of doing.

If you plan to keep them, I would slim them down a bit. As every other part of a plane, the landing gear should be as light as possible while still being able to serve its primary objective... which is in this case to support the plane on the ground. To me, without going too much into how they could or should work, they look a little bit to "fat" for just that.

On what level is this supposed to be critiqued? Are we comparing this to commercial game quality models? It looks like something that would have satisfied for the PS1 or N64. That may be harsh, but that's just how I view it. It's a bit too blocky and polygon-looking.

Ok, so funny thing is I am actually a Warhammer modeler as well, so I will admit I was a bit influenced by that. Funny you picked that out so quickly. I'm not really going for realism on the engines, since we are talking SciFi tech. So long as they look cool, I'm fine with that. I did end up getting rid of the landing skids, cause they just weren't looking great tbh.

Alright all, so here's some progress I've made (attached to the post). Let me know what you guys think!

The normals are looking better but they are "set to face" instead of averaged, so you get the pixely look.

great model all around except..
the circles on the bottom dont make sense. what are those suppose to be?
if they are suppose to make the airplane go a vertical distance then there is to many and they are kind of positioned weird.
if you looking at the model ...the whole airplane is nicely detailed but then you see those simple circles on the bottom its kind of out of place.

i think everything is good except those. prob doesnt matter anyways because depending on the game you might not be able to see that part

Yea those circles on the bottom are meant to be SciFi VTOL engines. It's a little tough to see in these photos, but there are individual fan-blades on them. How would you improve them?
