Hi, not only the left wall, but also the other two walls and floors. Please make sure it is a double-sided model without overlapping , then we can try to lower the Specular parameter of the material.

If the problem remains, please send the model file to ziyin.zhu@d5techs.com, as well as the scene file. Sorry for the inconvenience!

Regards,
Oliver

Hello, there are two common issue causes for light leak issue, please check them and adjust your scene/model:

  1. The model is single-sided and does not have a thickness, please add thickness for it in modeling software.
  2. The scene does not have enough lights for illumination, and the Exposure parameter is too high. Please turn off auto-exposure and add some artificial lights for the scene.
