Red Corners on Edges When Rendering With Cycles

[SimonEnderB]

(I’m quite new to Blender, and by extension, this website, so sorry if I have something wrong)

I have a confusing problem. The edges of my walls have red tinted corners.

I’m using Cycles, denoising, and I have a few performance features on, but I don’t know what could be causing this. Any help would be greatly appreciated!

Looks like subsurface scattering to me.

What is that and how could I fix that?

[SterlingRoth]

check the shader editor and make sure that subsurface is set to 0 on that material:

I must’ve misclicked. It was at 0.041. Thanks for the help!
