Could you specify:
- What exactly seems to be the problem? (“it’s not working” and 150 lines of code is not a problem or a question.)
- What did you try so far? Did you check other geometries / lights / setup / model viewers? Did you spend time trying to narrow-down the issue?
We’re happy to help and answer hard questions / solve specific issues - but if you’d simply like someone to do all the debugging and work for you, please consider posting in #jobs instead.
