I had tried it after Frenchy indicated it should work and I could not bring in the colors for whatever reason. So, I went searching for the long route.
I tried again after you answered and made sure the .MTL file was being created. It was. But, I THINK I thought 3D Builder was asking for the .PNG file when it was actually asking for the .MTL file. In any case, I now have the right workflow, thanks to you and Frenchy.
It's a LOT cleaner, too. With no image editing required!
I love hanging around with people smarter than me!
I have to admit that color 3D is a complete mystery to me beyond the simplest of levels. It's just plain voodoo! LOL!
Excellent last video and workaround! :)
