I've found an odd problem:
When I make a hint brush with all non-hint sides textured with hintskip the brush becomes solid. Visible hintskip sides have the null texture in game and if I look at the brush from the hint side I get a HOM, as if I textured it with caulk. I tried looking for the hintskip shader (radiant says it's textures/common/hintskip) but there isn't a "hintskip" anywhere in common.shader. There is a "skip" in the common textures in radiant, but this is just a texture. I'm using Ingar's 1.5 Linux builds. Has anybody else had this issue?
