The image works in Picturnaut (an HDR image viewer) and in HDRShop. But you are right, it does open black in Gimp. Which is weird because when I render a simple image, it opens fine in Gimp. When I resave the image in HDRShop (with no editing, just resave), it opens fine in Gimp. So there is definit...

Can you post one of the images that is acting that way?

That's weird. I just tried it. I did see a few artifacts, but overall it imported into Gimp (2.10.8) just fine.

If you are able to post the scene that would be helpful. It's likely that this is a back face vs front face issue.

The HDR output is not bracketed exposure, as you have pointed out. What it is is essentially raw output. HDR is "High Dynamic Range"; this doesn't mean it has multiple levels of exposure, it means the image data is not constrained to the standard RGB [255, 255, 255] range. It is what is called "floa...

Thanks for the link. We'll check it out.

You always have to be careful with Warehouse components. Some of those have weird stuff in them.

Oh, is that error message from V1 then? That would make sense. To my knowledge SketchUp 2015 on OSX was only ever released as 64 bit.

Where did you get your download? The file naming in the error log that you posted isn't typical for our distribution of Twilight Render on OSX.

Do you have Section Plane rendering enabled? If so, turn it off and try again and see if that makes a difference.

Otherwise, if you can send use the scene we can take a look at it.
