Hi,
I noticed that with EMT_TRANSPARENT_ALPHA_CHANNEL_REF the colors in the SMaterial are ignored.
This can be fixed by replacing:
Code: Select all
glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);
with:
Code: Select all
glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);
in the COGLESMaterialRenderer.h

Hm, I think that's the way the materials is supposed to work. It either uses colors or textures - no combination. At least I think that's the way it also works on other platforms.

I don't think so.
The OpenGL driver uses also textures and colors.
This makes also sense because if you don't want to use colors, just use white and you can get the same behaviour than without colors.

You are right. This got changed in the OpenGLMaterialRenderer after the OLG-ES branch got split off and hadn't been merged. My fault. Thanks for reporting - it's fixed in r4716. I've also added the other change for a LIGHTMAP material which was done at the same time in trunk.
