So you modeled the lacrimal as part of the face (have seen this as seperate object… maybe then the next things would be easier ?) ? I wonder what those tuts are… please tell. While not seeing enough about the eye geometry or the shader setup i would (wildly) guess:
- 1: maybe there is z-fighting between lacrimal and eye when this polys are too much in the same direction?
- 2: the lacrimal faces have to have an alpha blending in the texture and maybe also a mix with transparent shader to be transparent (cycles seems to be a but picky about that so this is the usaul trick… or are you using eevee ? then there are some opaques settings the remember…) and maybe a higher bounce value in render settings.
Edit: i just re-discovered a thread on BA i was watching but didn’t bookmarked
Further up there are also incredible things to see
