I tried this in the render method, the item "renders" but with no texture:

Minecraft.getMinecraft().renderEngine.bindTexture(new ResourceLocation("gammacraft","textures/models/TestTexture.png"));

 

also, it deleted all my mod's textures... :'(

 

please help

That looks like it should work. Have you checked that the pathname is correct?

 

Also, I'm not sure if I've ever tried switching textures inside an item renderer, although I can't think of any reason it shouldn't work.

 

Can you show us your whole renderItem method? There might be something else in there that's messing things up. OpenGL provides lots of ways to do that. :-)
