Hello,
I've been working on an interior scene with many different modeling sources. In the scene I had interior lights as well as HDR light coming through a window. I had assigned an image as both the HDR and as the background.
In the attached KSP if you adjust the environment brightness KeyShot should crash immediately. I deleted almost all the geometry for file size. I was able to replicate this on 2 Win10 machines.
Edit: I noticed my custom lighting preset gets deleted when I reopen the file also.
hi !
Try to save background image to a different format like PNG or open the image in photoshop & re-save as the same format in JPG or JPEG.
I've had to do this as well, not from a crashing standpoint, but the old program we used always used targa files, and for some reason KS doesn't like those, so I have to convert to PNG and everything is happy.
