OSL: Multi Gradient
The Multi Gradient OSL map has several gradient masking options.
Texture and VTex Errors
Topics pertaining to errors compiling VTF Textures from bitmaps in Source.
Collision Model & Physics
The Collision Model & Physics rollout in WWMT. Assign a collision hull, create a hull with the Quick Hull function and use advanced features such as the Convexity Hull Wrapper.
Displacement Texture Scale Sometimes Incorrect
Understanding Displacement Blend Texture Scale
This page explains one cause for displacement materials to be scaled incorrectly in Source as well as the solution. You should use bitmaps of equal dimensions in both materials controlling the Blend material.
Studiomdl.exe - Model has 2-dimensional geometry
Relates also to: Error with convex elements of Mesh
This error is usually caused by models having a $concave flag that do not have proper collision hulls.
