Hey, Rayscaper lovers (and haters?),

Rayscaper 0.9.8 is available in the SketchUcation store . It has more improvements, so we recommend upgrading to the latest version

What Changed?

1. Fix a self-intersection bug causing dark lines in CPU renders.

2. Add support for a near-clipping plane to the camera. With the near-clip plane, you can configure a near-clip plane at a distance orthogonal to the camera, and Rayscaper will cut away all geometry before the clip plane. It's not as powerful as section cuts (which are planned), but it can help for some use cases.

3. Improve the sliders in Rayscaper:

   • Every slider now supports dragging.
   • Scrolling is consistent across sliders. Each mouse scroll wheel increment/decrement will step up/down by one slider step value. Holding shift will step up or down with 10x the slider step value.

4. Make global illumination (GI) the default render method for new scenes. Using approximate GI as the initial render method might give new Rayscaper users the wrong impression because of its non-physical hacks and limitations.

Happy Rendering!

@Box Thanks for sharing those pictures. It must be a hard life for sure I assume this is somewhere in Australia based on the Whitsundays reference.

Hey, Rayscaper users!

Rayscaper 0.9.10 is available (0.9.9 was a test release) in the SketchUcation store. More good stuff so we recommend you upgrade to this version.

What Changed?

• Support for SketchUp 2024.
• Add a panoramic projection mode to the camera.

• Add an orthographic projection mode. The camera is the Rayscaper equivalent of the parallel projection in SketchUp.

• Optionally sync the SketchUp field-of-view with the Rayscaper perspective camera. Note that the FOV in SketchUp differs from the value displayed in Rayscaper because SketchUp uses a vertical FOV value while Rayscaper uses a horizontal FOV.
• Add a focal length control to the perspective camera. This is coupled to the horizontal FOV. I introduced this for users who prefer to work with focal length instead of FOV.
• Add a toggle to turn DOF on/off explicitly.
• Express the depth-of-field effect with a blurriness value instead of lens radius. This should make it easier to control the DOF effect.

• Bugfix: Ensure the rendered image keeps panning when the render restarts. Before this change, the panning would reset on every render restart, which was annoying.

Happy Rendering!

@majid Hang in there friend, an opportunity for someone as talented as you will come.

Hey, Rayscaper users!

Rayscaper 0.9.13 is available (0.9.11 and 0.9.12 were internal test releases) in the SketchUcation store. There is more good stuff, so I recommend you upgrade to this version.

What Changed?

• Fix flaky material picking. Sometimes, material picking would not work, or pick the wrong materials. This is fixed.
• Fix a cursor problem after viewport dragging; sometimes, the hand cursor would not go away.
• This release also features a simplification of the user interface:
  • Add more readable icons for the Rayscaper window.
  • Improved editors for the scene settings with more intuitive controls.

Reworking the editors was a significant code change, so let me know if something is not working or some things don't make sense to you. I'm here to help!

@Rich-O-Brien What an amazing result! Keep those Rayscaper renders flowing

Hey, Rayscaper friends!

Rayscaper 0.9.15 is available (0.9.14 was an internal test release) in the SketchUcation store. A lot of fixes and new things so I recommend you upgrade to this version.

What Changed?

Improvements

Desktop Scaling

Some users complained that Rayscaper was not legible on high-res, especially with display scaling enabled. I added a configuration option to scale the user interface to make it more readable on such displays.

Fast Tone Mapping

Improve the speed of the tone mapping operations. All operations now run in real-time, even on big render resolutions.

More Intuitive Exposure Control

Make the exposure slider more intuitive. Negative values darken the image, and positive values brighten it—an exposure step value of one doubles or halves the brightness. A value of 0 means a neutral exposure.

More Zoom Controls

Add zoom controls to the Rayscaper toolbar and the option to fit the viewport.

Fewer Watermarks

Although Rayscaper is commercial ( and I think it is a very affordable piece of software ), I also wanted to reduce the watermarking to improve the experience for free users.

Bug Fixes

• Add the option to scale the user interface. This makes Rayscaper a lot more legible on high DPI displays.
• Bring back the capability to configure the following texture types (cc: @sashapepperspray):
  • Noise Texture
  • Uv Texture
  • Mix Texture
  • Checkerboard Texture
• Bring back the double-sided and fake emission controls for light-emitting materials (cc: @majid).

@Mike-Amos

I would like to set GPU as the render default please, is this in the timeline?

Yes, this is in the timeline. @Rich-O-Brien asked for something similar. The idea is to save a particular configuration as the default and then load your preferred configuration whenever you set up a new scene. So, let's say your preferred default is "Approx GI" + GPU rendering. Every time you set something new up from scratch, that would be your starting default.

Also, the hearts un favourites (HDRI) seem to breed like bunnies on a motorway centre reservation. Can this be turned off please?

That's a nice way of describing it It's definitely a bug. The next release contains a big UI rework, and this should be fixed. Tap my shoulder if it isn't after the next release.

The orange and white (?) checker on the 'all HDRIs title here, what is that? Aberrant or intended?

Another bug, should be gone in the next release.

This is a quick tip for those who want to keep the Rayscaper window always on top. You can do this with a nifty utility called Microsoft PowerToys.

• Install PowerToys.
• Bring the Rayscaper window to focus and hit CTRL + WIN + T. The window should have a colored border and stay on top.
• To turn off this behavior, again, hit CTRL + WIN + T.

Will work for other windows as well, not just for Rayscaper

Well done @Mike-Amos !

@ntxdave Sounds good!

@ntxdave - In your test file, it had a ton of geometry generated in the model. If I tried to re-create your scene again, step-by-step I got this:

Can you try to just generate the grass on the plane, a first step and see if that works?

As a sanity check, you are using Rayscaper 0.9.72?

@Krass I didn't modify the materials, just used them as they came from SketchUp. But it's possible ofcourse:

But maybe it's more intuitive to use the alpha channel from the color slot immediately if one exists?

And here are some teapots in the night

Here's a quick video on how to use Rayscaper with Skatter. Still trying to get better at making video content

@ntxdave Sorry about that, this seems like a real bug. I will investigate!

@ntxdave Can you provide some context on what's now working?

As soon as you have a Skatter composition, click generate, and the skattered items should appear in Rayscaper. I will create a demo video later. It would be great if you could provide a screenshot (or video) of what youare seeing. Just saying "it doesn't work" isn't providing me much to help you.

Hey, Rayscaper users!

Rayscaper 0.9.72 Beta is available. You can get it via:

• The SketchUcation store.
• Direct download: link.

I recommend upgrading to the latest version.

What Changed?

• Rayscaper now supports direct integration with the Skatter plugin. Render-only Skatter data can now be ingested directly from Skatter, bypassing the
  SketchUp viewport. This offloads complex instancing and geometry handling to Rayscaper, keeping SketchUp responsive and lightweight during rendering.
  Perfect for large vegetation or scattering setups — just hit render and let Rayscaper handle the heavy lifting. (@ntxdave Thanks for connecting me with the Skatter people).
• Bugfix: push/pull geometry would not properly propagate to Rayscaper.
• Fix Rayscaper for SketchUp 2024, caused by a breaking change in the SketchUp SDK. Note: Going forward, Rayscaper will only support the latest three
  SketchUp releases because now that it's for sure that the SDK is not backwards compatible, it's too much overhead for me to maintain more versions. The
  current version supports: SketchUp 2026, SketchUp 2025 & SketchUp 2024.
• Make materials assigned to a SketchUp group or component instance work again. cc: @sashapepperspray

Here's a screenshot of a simple forest I created using Skatter:

That's a very cool axe!

@Krass I sent you an e-mail with a test build. Let me know if it works (or not).
