How to solve the facula problem in 3d rendering?

1, check the spots caused by camera spatial coloring association.

2, the light spot caused by the crystal lamp material

The model with more equal surfaces of crystal lamp has more reflective surfaces, and under the action of light, the light spot is caused by calculation error.

3. Spot caused by photon sampling value

It's okay to test the small picture, but the big picture will have light spots if it has shadows. It is recommended to change the sampling value to 0 (automatic).

4. The wrapping material endows the self-luminous material, which will produce light spots.

5. Spot caused by GI parameters produced by packaging materials.

The generated GI of packaging material is greater than 1, which may lead to light spots.

6. Check the facula caused by probability light.

7. The light spot produced by the first rebound of the main image of light.
