Here is a real picture of water to illustrate the correct behavior.

Yes, I've spent a fair amount of time studying why we see the stretched specular reflections on a sunset over water and I understand the reasons why it happens.  I just hadn't considered that the microfacet calcs …

I have some 3D models of food and animals that I need to make for various games. However, I am wondering how I will be able to use textures. I have Adobe Substance and Creative Cloud, but I don't know how to acquire images to use for textures without having to take close-up photos of things. I know…

“IBL” just means you're getting lighting from an image. Any method for sampling lighting from an image is IBL, what the OP is doing here definitely qualifies. There are of course many other options for implementing IBL, such as pre-filtered cubemaps and other related techniques.

If your image has sm…

A rough surface does not actually become “100% reflective” at a grazing angle. The trick here is understanding how microfacet specular models work. With microfacet specular, there is not really just a single normal for any point on a surface. Instead you can imagine that the point you're shading is…

@Lexxisriennnl oh wait, are there any PBR courses in udemy? cant find any, or most of them are related to the art side and not the dev side, let me know if there are courses in udemy you can recommend as well

Quick update, I think this structure should cover it all:

• PBR material data-structure
• Shaderpack override
• Texture: diffuse/albedo
• Texture: normal map
• Texture: roughness/AO/disp + metallic (RGB grayscale, A on/off)
• Bool fullMetal (false -> no need to fetch metallic map)
• Bool fullNonMetal (false -> no…

I skimmed through it a bit.

From first look it seems interesting and decently short for tutorial purposes.

Thanks.

I did not want to integrate Mitsuba either, so wrote my own Pathtracer.

Well, if we are talking about reducing the amount of work then I already have a solution - use Arnold.

Creating realistic digital humans for real-time 3D animation is now possible with Reallusion’s new Digital Human Shader. A complete set of shaders for skin, eyes, teeth, and hair are available, along with SSS(Sub -Surface Scattering) and Micro Normal updates for iClone 7.7 and 3D character creation…
