After much messing around I think i got something acceptable. First of all, transparencies MUST be .png, I don't know why but other formats will cause issues. The eyelashes I fixed them applying 4 layers of LerpAlpha. Finally something than at least isn't darkened by the Alpha Threshold. http://oi60.tinypic.com/10pwyyq.jpg Alpha Threshold alone It looks meh. After that, I duplicated the hair mesh and i applied Alpha Threshold to one material, and LerpAlpha with 2 layers to the other mesh. This Is the best looking so far but it has 2 terrible flaws... It can't receive shadows and it duplicates the hair polycount. http://oi58.tinypic.com/xmrjag.jpg Alpha Threshold + LerpAlpha Shadows of the first method vs the second one. http://oi58.tinypic.com/2w5lonq.jpg The right one (Alpha Threshold + LerpAlpha) receives shadows in is Threshold layer but get overwritted in the Lerp layer, so we can barely see them. Luckily both of methods work OK with illumination. http://oi58.tinypic.com/xm5rb8.jpg So that's it, I'm already out of ideas. I think this can be improved with a shader that do 2 passes, one Threshold and another Lerp but with shadows. Saddly that's out of my range. Any more ideas?
