@a63nt-5m1th Thanks again Agent Smith. That one had me puzzled. I'm quickly moving from total noob to noob apprentice.
So I finally managed to change the texture, just a proof of concept, on this table prop that was not cooperating.
Thanks for your tip of using .odr.
One interesting thing. When I did the first pass importing back in OpenIV it went smoothly.
The second time it created an error with a missing file, wrong path. Inspecting the files path was correct and file was there??
So in frustration I just dragged and dropped the .odr into OpenIV. Loaded perfectly. Go figure.
Once more I really appreciate all your help and tips and clarifications.
I doubt I'll ever be in a position to returrn the favour though.
Table in back is standard prop. Table in front is just test, replaced texture in PS and created addon.
Ok, I figured this one out. For some reason, using Props Editor 1.1, I could not simply create it with Props Add Manual.
This one, not sure why, needed Props Add Json. So i created the Json and that fixed it.
