twosided and forceshadows on metal texture

[angua]

I found twosided and forceshadows applied to a metal texture (metal/flat/heavy_rust_pocked01), which produces problems ingame (looks like the texture is z-fighting with itself). Springheel, did you add that when you used that texture for the new weapons? Looks like we need a new shader for those cases.

[Springheel]

Yeah, I did add that. I'll make some new shaders for them. I wonder why that doesn't work on brushes?

Thanks!

 

It kind of looked like it was z-fighting with its own shadow, it was partially lit and partially not lit, depending on the view.

 

Edit: that's what I found on iddevnet.com:

twoSided

Draw the front and back. Implies no-shadows, because the shadow volume would be coplanar with the surface, giving depth fighting

so this really seems to be the problem. I wonder why this is not visible on models.

[Springheel]

I don't know...it appears to be working alright on the models, but maybe something will crop up.

I don't know which model uses such a material and looks good, but the best way around it is to make double sided polygonsin 3d app with tiny offset. Doublesided keyword is OK only for nonshadowacasting surfaces.
