Shadow volume visible????

to stop rendering shadow volume just disable backbuffer writes
glColorMask(0,0,0,0)
or
device->SetRenderState( D3DRS_COLOWRITEENABLE, 0 );



BTW: when using shadow volumes don't use TnL lighting(ambient material's etc - why do you need it?)

Ahh, thanks.

I'm using TL basically because (as a low-cost shadow option), I'm looking at using a static cylinder to be the shadow volume (saves the processing time needed to build the volume). Seemed like a quick and dirty way to do it instead of creating the cylinder in code... will probably end up doing it that way eventually, but this is for a quick test kind of thing - hoping it'll be faster than using a shadowblob decal.

hey thanx! this cylinder seems to be a good solution for me, eve though you didn't know it while replaying:) I didn't realized that I could do blow shadow this way!

No worries. Just got a bit of a shock though, forgot that the colorwriteenable isn't a boolean.... set it to 1 and everything went PINK! Total freak-out, but it has given me a neat idea for some special effects.
