My enigmatic room.

I made a new study, I have some problems with textures and plants, apart from that, I am waiting for your criticism to improve myself.

Looks cool but your lighting is kinda broken

I think it might have to do with your normals

Same for the plants, make sure in your 3D modeling software that the normal are not inverted, and for the plants that they are pointing in one direction ( it helps the readability of foliage )

There is also some problem with your UVs, some textures are way more stretched than others, be careful to have the same texel density for all your assets ( the wooden window frame laying on the floor also seem to have UV problems)

Also if you are using Lumen be careful that your assets have two sides, because light tends to bleed through the faces and it might also be why light seems to bleed from your corners ( if you don't want extra work of modeling back face just use a cube with black texture behind it to cover the light that might get in )

This information is very valuable, thank you very much.
