Hi sticki -
First, I’ve asked a colleague who works with a 4K Monitor to look into that issue and as soon as I hear back from them I will let you know.
Second, nothing should have changed between 4.7 and 4.8 which would have altered your tessellation material. So, let me take a step back and ask a few basic questions again to make sure I am attempting to reproduce this issue correctly on my end.
You said that the original mesh in 4.7.6 imported without issue. When you imported it into 4.7.6 did you import materials created in Max into the project? Also I assume you combined meshes on initial import, let me know if that is not the case.
When you moved to 4.8.0 (or 4.8.1), do you open a copy of the project with the assets already created in 4.7.6 or did you create a new project and migrate the assets over, or did you create a new project and copy and paste the assets via windows explorer? If you did not just open a copy of the project, did you try to Fix Redirectors by right clicking the Content Folder and “Fix Redirectors”?
Let me know about these questions -
