Hey Mike,

I have already ticked 'use gpu rendering' a while ago when the system was changed.

I just wanted to check if the model renders correctly with the CPU and try to isolate the problem to GPU rendering.

It does render for me using GPU rendering; the model is surprisingly polygon-heavy. I do see the same problem with the flames texture and the alpha channel:

I guess you are using the same flames texture in Twilight Render. I'm surprised it gives such a nice result because this flame texture doesn't have a clean alpha channel. There's a pattern in the alpha channel:

Does Twilight Render have a way to display thumbnails for textures? I'm intrigued at how it can render this so cleanly.

Cheers,
Thomas

I spotted the alpha chanel stuff earlier when attemping to use that =texture for the log fire in the cold view scene. Weird.

Transparency png are flaky tbh and I am looking to 'try' with 3d flames, I shall need a lot of paracetamol for that though.

No idea if Twilight has any fanciness in this respect, Fletch and Chris are now gone so, relying on my daffy memory which is seive quality.

I have notice that having a backgrounbd which has some commonality to the transparency helps. The red/scarlet works best here.

I have attempted to recreate a scene with cutaway and limiting nayural light to that provided by the geometry, windows etc. Many splats with no report just the windows desktop.

I shall leave this here, needs a lot of adjustemnt lighting levels wise but gives a reasonable render potential.

The semi opaque walls, not so sure about.

Adjustment.

OK, finally got the onboard graphics online, adopted the classic engine in Sketchup and rebooted. Produced an immediate error in windows which I hope is a transient.

I think there is an improvement in this image, same view and same render time but 'feels' better. Opinions?

@Mike-Amos said in Post diagnosis.:

When you mention onboard are you referring to integrated graphics in a CPU like Intel UHD? Or is this onboard the GPU?

I'd be concerned by the 'immediate error' as that suggest conflict.

Sorry, I do not think the graphics are the issue.

Something about megascans when I restarted Sketchup after making the changes in BIOS.

I am seeing a thirty second or more delay when selecting, painting a surface or importing an object which is something I have been seeing anyway. SKetchcup can take a minute or more to load to the welcom screen and then open a model even one saved to the OS drive.

Having said that, I sometimes get a onedrive saving error "Cannot save, this file is already in use by another user", this turns out to be a one drive folder in my microsnot account. These two renders were consecutive and I have no clue. The bonus is that in true architect fashion, the second render does bring the garden "Indoors"......
