I have my model retopologised in Blender 4.1.1. Here it is;
I opened that same file in Blender 4.2 and this is what I get;
I tried opening earlier saves of this file and the result is the same.
Does anyone know what is causing this to happen and how I might correct it? I would love to continue to work on it in 4.2. Thanks
Make sure there are no incompatible add-ons involved. If not, file a bug report.
thorn, How do I know what is an incompatible addon? I have the same addons in 4.1.1 that I have in 4.2. Probably fewer addons in 4.2 as I haven’t had a need for them yet.
Here is the list of enabled addons;
Thanks for your reply.
I unchecked many of the addons the ones from 3rd parties but the problem remains. I filed a bug report and included the file and the two screenshots.
If it is a bug I hope it can be fixed.
I noticed that it takes about 10 to 15 seconds for Blender 4.1.1 to start on my computer while Blender 4.2 begins in just over a second.
I added a MultiRes modifier to the retopo’d model and a Shrinkwrap modifier. I applied the Shrinkwrap modifier. I set the MultiRes to 3 subdivisions and saved it all in 4.1.1.
I then opened it in 4.2 and it all looks fine. So at least I am good to go in 4.2 from this stage forward.
It will be nice if they could still troubleshoot the original problem.
Try applying the modifier again
The Shrinkwrap modifier seems to be working strangely. 
Hi Kim,
Thanks for the reply. I tried what you suggested but nothing changed.
