Only apply shader ot surfaces that are less then 90 degrees

[Captain Cody]

Any way to only apply a shader to a surface that is 90 or less degrees? If that makes any sense, for example; apply it on side walks but not on walls.

world normal.z should be close to 1 - That means that surface normal points up. There is a snow shader that uses that condition: https://community.multitheftauto.com/index.php?p=resources&s=details&id=3419

I was trying to modify a snow shader to only apply to flat and slightly curved surfaces. That is in fact that one I was using. Doesn't work, could it have something to do with all custom objects?

If it works for gtasa map then it should work for other objects as well. Check out shader roadshine1 - if it works properly for those objects. The issue might be that the objects don't have proper normals. Use kams script to export objects from 3ds - some other scripts mess up normals to prevent dynamic vertex lights from blinking - but also prevent mta from generating normals.

Well what I did fixed it for me. due to there only being a small variety of texture names. (Just general *road*,*grass*,*concr*) not to sure why the surface direction thing is not functioning because it's a direct conversion from VC and LC so there shouldn't be any issues with the models.

actually custom objects have this issue with directional lights https://community.multitheftauto.com/index.php?p=resources&s=details&id=10186

Some don't - the ones that have normals set to (0,0,-1) for every vertex have this issue 'fixed' but any shader that uses normal works improperly.
