Twilight Render User Forum

I've updated my Sketchup pro to 2022 and then also installed the latest version of Twilight pro v2.16 - after installing the twilight plugin, my sketchup crashes immediately upon opening an existing or new file. If I uninstall twilight, my files open with no problem at all, so it must be something with regards to the latest version?

I have a Windows OS.

Hi Cornelius,
It seems likely the issue is the Twilight Render Denoiser. We sent you an email with instructions. Hopefully we will be able to get it worked out.

Greetings
I have been rendering in Twilight with great success but suddenly on a new design a get a Bug Splat as soon as I start a render. I have tried rendering previous designs and it works great. Just the new one is Bug Splatting. Any suggestions ?

What render method are you using? If you are using one of the Low-High methods, then try the Interior. If that works it may have to do with memory and the use of light-emitting materials (which should be avoided when using the Low-High render settings).

Otherwise, there may be something in the scene that Twilight Render is choking on. We would have to have the scene to know for sure.

Please follow "Preflight Checklist" carefully.

Some culprits in the past with similar problem:

1. accidentally applied a light emitter material template to a surface that is not intended to be lighting up, and now there are thousands of lights accidentally in the scene
2. too low RAM
3. strange format texture file
4. odd component inserted from 3D warehouse or other 3D object website that is causing issues.
   no lights in scene
5. lights or camera intersecting adjacent geometry such as light fixture or a wall
6. Run Diagnostic and read through and see if anything stands out to you as strange. You can copy/paste results here as well. Extensions>Twilight V2>Diagnostic Report

Please share a link to download the scene and we will diagnose.

I am also getting crashes on my MAC Monterey 12.4 using twilight render and sketchup pro 2022 when using sky rotation.and exploration render. When I rotate the sky, spinning wheel for extended time (4 minutes and counting)

Not sure if this is causing the crash but it could be. You’re using a spherical sky hdr .You should uncheck the “sun enabled” box. Your light will be provided by the hdr image. Also I’d lower the brightness setting back down to 1.0 . It would be unusual to have brightness set as high as you have it.

HDRi strength should be left at power of 1, then you use Post Process button in the render dialog to adjust the tone mapping (brightness/darkness) of the final image.

This is because the HDRi is shooting out a lot of info, and if you boost the power, it can introduce artifacts.

Said another way, a normal .jpg image has power from 0-255, then if you boost it, the power can go up by multiples of that boost number. But with HDRi, it already contains information from power of 0-50,000 so by boosting it, it is not saving you any render time. The engine is trying to figure out the reflected light bounces from all that information.

Hope this makes sense?

Hello,
I encontered the same problem as Cornelius, could you please send me the instructions that seem to have worked for him?
Thanks

Are you using the Fast Forward Denoiser? If so, what kind of GPU hardware do you have? What is the version of your nVidia driver?

If the denoiser is the problem, you can disable it by going to "C:\Program Files\Twilight Render 2" and deleting the TwilightDenoise.dll. This will prevent the denoiser from initializing. But this will only work if the denoiser is conflicting with your current GPU hardware. If so, we can send you a link to an old version of the denoiser that might not conflict.
