Skin appearing white in 3Dlight render

odastein

So, the skin of two figures appears white/isn't rendered at all in my last 3Dlight render (see attachment). What could cause this? (for the record, other figures appear normally).

I see a number of warning like these in the log file (don't know if it's related) :

2019-02-27 03:29:31.491 WARNING: libpng warning: iCCP: known incorrect sRGB profile
2019-02-27 03:29:31.504 WARNING: libpng warning: iCCP: known incorrect sRGB profile
2019-02-27 03:29:31.533 WARNING: libpng warning: iCCP: known incorrect sRGB profile

I also see the following message appearing in the 3Dlight window :

3Delight message #45 (Severity 2): S2069: the interface of shader 'C:/Users/User/AppData/Roaming/DAZ 3D/Studio4/temp/shaders/brickyard/{407f8e5c-3a9b-4708-b5e5-799ff1fe7c1d}/shader_Surface.sdl' is invalid

3Delight message #45 (Severity 2): S2069: the interface of shader 'C:/Users/User/AppData/Roaming/DAZ 3D/Studio4/temp/shaders/brickyard/{407f8e5c-3a9b-4708-b5e5-799ff1fe7c1d}/shader_Surface.sdl' is invalid

is the one that matters, it means that the shader used (probably the AoA SSS Shader) did not compile correctly. Soemtimes just re-rendering will fix it, if not you can try clearing out the C:/Users/User/AppData/Roaming/DAZ 3D/Studio4/temp/shaders/brickyard/ folder (either by manually deleting its contents or by reloading the scene) to force a recompile.
