Screenshots/Videos Description:

Steps to Reproduce (optional):

Hi, do you have some other light source in this scene? besides, to confirm, do you mean this shadow is not right?

Thanks,
Oliver

Yes! It’s that shadow, there is no more source of light there.

Thanks

Hi Juan,

Could you share the scene file( the whole folder) to support@d5techs.com, or to me ziyin.zhu@d5techs.com? We saw the shadow is strange, but without the scene file we could not repro or narrow down the cause.

Thanks in advance!
Oliver
