@Krass Great renders! Glad you found a workaround. That computer screen looks believable to me.

(www.krea.ai)

You render it grainy in a low res, and then let it upscale? Or do you enhance the images in other ways with AI?

BTW, I found the issue, will post a fix shortly. The crash occurs when you load too many thumbnails in the asset browser.

Cheers,
Thomas

@Mike-Amos Very nice render!

Hey guys,

Looking into the crashes.

Hello, if I leave Rayscaper open and import a texture directly onto a face (with the import tool) it crashes

Was this on the first texture, or after multiple imports?

I can't create an emissive material with an image, if I increase the power the image disappears and the texture is white. I can't make a monitor screen. Can someone help me?

Currently, Rayscaper doesn't support emission with a texture. Which image are you talking about? Maybe a screenshot of your setup helps me understand it better.

Another crash when reopening RS and trying to apply a texture

Looking into the crashes, I think (I hope) I found the root cause.

I understand the frustrations, and I appreciate your help in making the software a lot better!

Cheers,
Thomas

@Mike-Amos Version 0.9.68 is out now, can you confirm that it fixes the crash you saw earlier today? Thanks!

@Mike-Amos Thank for reporting. Sorry about that!

I can reproduce the crash on minimizing, not on closing the Rayscaper window, though. Working on a fix.

Amazing!

I created a hotfix for a crash and updated to version 0.9.68 Beta - please ensure you get that one.

Hey, Rayscaper users!

A new release, with some cool stuff!

Rayscaper 0.9.68 Beta is available in the SketchUcation store. As
I recommend upgrading to the latest version.

What Changed?

• Support for SketchUp 2026.
• Draw overlays for the lights in the viewport. This allows the user to select the lights in the viewport directly. You can enable
  or disable the overlay in the viewport toolbar.
• Save the layout and position of the Rayscaper window between sessions. You can reset the layout via the menu "File >
  Reset Window Layout".
• Fix a crash when minimizing the Rayscaper window.

Here's the light overlay feature in action:

Hey @kacper7

I'm the creator of Rayscaper, a render program: https://rayscaper.com/ - How easy is it with your software to inpaint things or edit the render without actually changing the mood of the render? I see people here on the forum using Rayscaper render and then using ComfyUI to add people or vegetation. I'm not well-versed in AI models per se, but I see you offer API integration. So I wonder if I could use that to sprinkle some AI features on top of my own software.

See for example this post: https://community.sketchucation.com/post/1616622

Cheers,
Thomas

Are you thinking of adding node-based material authoring to Rayscaper?

Maybe... - I was more thinking in the line of adding MaterialX imports so that users can easily import materials made by software like this or Substance Designer.

Just out of curiosity, has anyone used Material Maker before to create PBR materials? https://www.materialmaker.org/

Cheers,
Thomas

Here's a version with an HDRI map background
But I'm trying to make a "studio" render for a friend, and Sketchup crashes when I change the image resolution during rendering. I set it to 300x400 and double-scaled it twice, and it crashed both times. Should I send a crash report?
https://jskup.fr/wp-content/uploads/2025/09/rocking-chair-3-Phil94.jpg

Making sure I understood you correctly. Just changing the resolution (of the rendered image) in Rayscaper made the software crash?

@Krass said in Rayscaper New Releases:

I paused the rendering and changed the definition, and it didn't crash... "studio" version raw rayscaper

Nice render, it doesn't seem to have the correct tags in the forum post because the picture is not visible for me immediately.

@Krass Wow, that's jaw-dropping. Congratulations. Great work!

@Krass

To clarify, updating the PolyHaven HDRI size will change the size of the textures after a restart:

I will not update the HDRI images/textures you are currently using in your scene. You can check the actual size here, but I should also display the HDRI size more prominently in the UI.

If you want to use the larger size, reapply the HDRI later.

I hope that clarifies things!

Regards,
Thomas

@Krass, just as a sanity check, you are not changing the name right, and not the component definition name?

Hey, Rayscaper users!

Another release!

Rayscaper 0.9.64 Beta is available in the SketchUcation store. As
always, I recommend upgrading to the latest version.

What Changed?

• Fix weird artifacts in the interactive render viewport.
• Fix the upside-down images when saving.
• Add transmission support for the PBR material. This makes it possible to create glass or liquid materials with the PBR material.
• Fix a regression when renaming light components. Rayscaper lights should now correctly use the name of their SketchUp
  light component again.
• Fix glass rendering, when multiple glass surfaces overlapped, Rayscaper would render them too dark.
• Fix the render timer in the viewport. It will stop counting when the render is paused or finished.

@Krass Very cool, I didn't know about ComfyUI; I'm going to try that out. Thanks for sharing the workflow!

@nickchun can you also mail me the file for which it keeps crashing? thomas@rayscaper.com.

Thanks!

@nickchun, can you send me the log file immediately after it crashed? That would help me debug the issue. You can find the log file under C:\Users\YourUserName\AppData\Roaming\Rayscaper, the file is called SUEX_Rayscaper.log.

It should not crash because your PC is not beefy enough.

Thanks!
Thomas

@Krass said in Rayscaper New Releases:

yes, but for now if I rename RS lights components, they all shut down

Sorry about that; I just noticed there's a bug here, and the renaming of lights is now broken. I already have a fix and will make a new release very soon.

Cheers,
Thomas
