Nice results!

@mike-amos Thanks for sharing the scene. That helped me figure out the issue.

The glass windows in your scene are modelled as 100% transparant (opacity = 0%).

I'm getting technical here, but Rayscaper internally only allows for 8 transparent ray bounces. After 8 bounces, the ray terminates without contributing any light which results in the black windows. In your scene, there's a bit of bouncing around through multiple layers of glass, hence the black windows. In the next release, I will make the number of transparent bounces configurable as well so that you can bump it up to higher values if required.

After

The fix will be available in the next release.

Cheers,
Thomas

@Mike-Amos Do you mind archiving the scene and sending it my way? I will have a look.

Cheers,
Thomas

@Mike-Amos Under your render tab, what is the max depth? In scenes with a lot of glass, it could be that you need to increase it. Let me know if that helps.

Nice results Mike!

Hello,
On my end, after installing it on 2024, it didn't work and SketchUp started freezing systematically on both PCs. It's impossible to fix, and I'm currently forced to use 2025 without extensions...because I hadn't installed RS on version 2025, which I don't use

Can you try deleting Rayscaper directly by removing the following files? Make sure SketchUp 2024 is not running:

Let me know if that helps.

@Rich-O-Brien Thanks for confirming.

Hey everyone,

I’m investigating reports that Rayscaper 0.9.94 Beta does not launch for some users. This does not seem limited to one SketchUp
version, so reports from SketchUp 2024, 2025, and 2026 are all useful.

If you are affected, could you please reply with a few details?

1. Which SketchUp version are you using?
2. Which Windows version are you using?
3. Was Rayscaper 0.9.94 a fresh install, or did you upgrade from an earlier version?
4. If you upgraded, which version did you upgrade from?
5. How did you install or upgrade Rayscaper?
   • SketchUcation ExtensionStore
   • Manual RBZ install
6. Does Rayscaper appear in the Extensions menu?
7. What happens when you click Extensions > Rayscaper > Start Render?
   • Nothing happens
   • An error appears
   • The render window opens and closes
   • SketchUp crashes
   • Something else
8. Did Rayscaper 0.9.93 work on the same machine before upgrading?

Please also mention if uninstalling and reinstalling changed anything.

Casting a wide net here because I'm having trouble reproducing it on my own machine.

Regards,
Thomas

Nice! Looks expensive.

Hey folks,

Just wanted to let you know that @majid is safe and trying to ride out the rough times.

Let's keep him in our thoughts.

Dear Thomas,
I hope you and your lovely family are doing pretty fine.
After weeks of internet blockage, now the only working service is "gmail" 
though not fully functioning!
Reached out to say we are doing fine and hope it passes with minimum 
life-loss heading off a better world, brighter minds and more peaceful 
communication despite all intolerance and dogma we are witnessing.
Take care and convey my best regards to your lovely ones and friends 
on Sketchucation. 
Regards.

Let us know if you need more help.

@Krass

Thanks for the report, I can confirm the error with GPU rendering. Would you mind sending me the scene so I can try to reproduce the error?

Thanks,
Thomas

Hey @Mike-Amos,

Could you provide a screenshot? Here's what I see when hiding the assets panel. As you can see I still have a progress bar, so I think we are talking about different things:

Rayscaper users, a heads up: I accidentally uploaded the previous 0.9.92 version to the SketchUcation Extension Store. If you installed Rayscaper in the last 4 days, you may have reinstalled the previous version. (@mike-amos Thanks for the heads up!).

I’ve uploaded the latest 0.9.93 version now. If you download and install the extension again, it should install version 0.9.93 correctly.

Apologies for the hassle.

Happy Rendering!
Thomas

Hey, Rayscaper users!

Rayscaper 0.9.93 Beta is available. You can get it via:

• The SketchUcation store.
• Direct download: Rayscaper_Win_0.9.93_Beta.rbz.

I recommend upgrading to the latest version.

What Changed?

• Fix SketchUp tag visibility updates for nested groups and components. Nested geometry now appears and reappears correctly in Rayscaper when you toggle tags in SketchUp, matching the SketchUp viewport more reliably.
• Fix material picking when hidden or invisible objects sit in front of visible geometry. The picker now selects the material you clicked instead of the hidden object blocking it.
• Fix crashes after exploding SketchUp tag folders and then changing tag visibility.
• Improve viewport navigation and panel controls with a simpler pan/zoom path and a fixed panel layout.

Hey Mike,

I'm sorry to hear you're running into these issues with Rayscaper. Would you mind sending me this scene so I can have a look?

Summarizing your woes:

• Auto-exposure is behaving strangely. Mike, I'm still not sure what you mean by this.
• Geometry does not appear in the renders.
• Viewport shows CPU, while you have enabled GPU rendering.
• Rendering fails.

I think it's easier if you send me the scene and, preferably, the logs when such a render failure occurs (https://www.rayscaper.com/getting-help/report-a-bug/#1-export-the-log-files), so I can try to reproduce/fix these problems.

Thanks,
Thomas

That’s definitely also a bug with software. I’m away this week so the next release will come a bit later, but it I will try to fix this there.

Good stuff mike!

You mentioned that auto-exposure is doing funky things? Is the image below using auto-exposure? If so, what does it look like without auto-exposure?

For the window glass, make sure you are using the glass material with thin & transparent shadows:

Cheers,
Thomas

Magnifique!
