**D5 Render Version:I used PRO for the first time yesterday.
**Graphics Card:NVIDIA GEForce RTX 4060
**Issue Description:When currently rendering, it appears like the uploaded photo. The black part on the left and the textured part on the right are on the same layer, and no matter what you do, they are expressed dark like that.
**Screenshots/Videos Description:

Hello. Which version of D5 are you currently using? Please let me know the exact version number.

Also, which modelling software are you currently using? What did you use to import your model, directly or using a plugin?
You could check if the UV size of the mapping causes your current problem.
