Rendering material incorrectly

My SketchUp rendering is showing the gold finish on some parts of the shelves darker than other areas. I’ve confirmed that all faces are front-facing, adjusted the shadow settings, and verified that the material is applied consistently, but the issue persists.

still showing a different (darker) color.

What rendering application?

Share the .skp file so we can see the exact setup.

Make sure you don’t have 2 groups / components on top of one another. Easy to do when copying or embedding things into groups.

Also - move the lamp.

SketchUp 25 using V-Ray. The file seems to be too big to share.

Moved to thecorrect category.

Upload it to Drop Box and share the link.

If you’ve applied too much softening in SketchUp - the normals can break and cause reflection issues - try selecting the whole object and setting it to 0 and see how it looks

Must be something wrong with the link. I get this:

Do you mean attached? Because I do have two components attached, but not on top of one another.

Do you mean two groups/components attached? The components are attached but not on top of each other.

It renders totally fine for me in the latest version of V-ray

A couple of objects aren’t loading but that’s because I don’t have the corresponding VRscan on my machine.

Could that be what is happening for you?

This is what I see in Vray. Same sort of thing Adam shows.

I don’t get it. It’s showing a darker color when I render. Almost black.

Could it be something going on with the installation? I’m using a Mac.

If you view the material in the material editor in V-Ray how does it look?

Perhaps it’s the Vray version like Adam suggested.

Maybe but I kind of doubt it. Maybe hardware related?

BTW, I would suggest cleaning up the model. It probably won’t affect the rendering issue but it will improve performance. It does on my machine anyway.

Will do. It’s strange—I closed the file and reopened it, and now the V-Ray render screen is displaying the material correctly. I’ve been experiencing several issues with SketchUp since installing the 2025 version; I often have to click multiple times for Save or other commands to respond, which is frustrating.

Why aren’t you using SketchUp 2026?

Update to 2026.
Make sure VRay is updated.
