I have a couple of questions regarding textures and performance.
1
If I 2 vmt's referencing 1 vtf file will this have increased performance over 2 vmt's referencing 2 vtf files?
2
If I have a map with the ground texture with 2048x2048 (probably going down to 1024x1024 soon) is it worth making a seperate low res texture for the skybox?
3
Is there a shader parameter to disable light mapping on a world texture. I tried unlitgeneric but it removed the colour tinting from the sun? (alternatively is there a way to stop brushes with certain textures from casting shadows?)
4
I heard mipmaps actully inhibit performance due to increased file size, this would make sense since the entire texture is still loaded regardless of the distance from it. Is this true?
Thanks
