Not a render critique request.

I downloaded a scene for practice.

Straight out of the box the back wall has an emissive quality I did not give it in Rayscaper or anywhere else.

I know but you have to laugh. Checked settings in Rayscaper and everything is standard so hoo nose?

[Rich O Brien]

Is this Rayscaper? What are the settings for that material?

[Mike Amos]

G'day, it is Rayscaper and the mat has no settings attached. Just a simple out of the box view.

The scene comes from render hub, https://www.renderhub.com/maker20/modern-luxury-style-bedroom-19.

OK, I am still experiencing an issue where if Rayscaper is running while minimised, attempting to pan the SketchUp scene results in a bug splat. Thomas is on it already but this appears to be part of an escalating series of failures.

All part of the process.

Is your environment just a plain white background? That would explain the back wall. Or rather that the back wall is missing and the environment is visible.

Regarding running a render while doodling in SketchUp. I don't do that because it rendering is already taxing the system.

BTW, that link points to a kitchen. Not a bedroom. I didn't create an account to check the download though.

Sorry about the link, brush like today. https://www.renderhub.com/maker20/cozy-bedroom-interior-scene-005

The back wall is textures, you can see the texture on the wall on the left of the illuminated panel.

No missing geometry.

[Rich O Brien]

Something is off with the back wall's scale.

But if you explode and regroup it fixes it.

Thanks Rich, just flat out did not think of that.
