Will materials make it to HL2?

I mean to say, the materials we create in the ModTool, without a texture, like procedural, or just plain colors, will they be included in the SDM export and show in HL2?
I believe I read somewhere "they won't", so I thought of double checking...

JDL

If I correctly get what you mean, no.

Unless the mod tool has a diferent way of doing that, the model will just show up with a purple-checkered color if you dont' assign a material and a vtf texture file to it. The engine (or editor, or viewer) will simply act as it doesn't have any texture.
