"Sometimes there's issues with them in VS. PNG & WebP are the recommended formats. That's about all I can tell you"
"In the regards to the images, they look like they were created with a 3D graphics program, so yeah I'm not really following. Did you make the original graphics in a 3D program or are they stock images/models you have found online & are now touching up/editing in Gimp?"
I create everything myself with blender and daz and gimp
thanks for the "3ds" file, I'm testing it and it works for now
thanks for your help and have a nice day
