Hello everyone! After testing all the possibilities and suggestions from the DevCommunity and various forums with others who had a similar problem, it turned out that different projects have different solutions. In my case, there was actually just a very small mistake I made. Two faces from the same mesh were colliding with each other, and had emissive materials. If anyone has a scene with lots of emissive materials and encounters this issue, you can follow these steps:
- Turn on LIT mode.
- Check each mesh one by one.
- Identify which mesh with emissive material turns to a white color (not the material’s actual color).
- Then, fix it accordingly.
I hope this information helps! Thank you for your support and contributions in the forums.
