This release is outdated. The latest release is now 0.8.12 Alpha, and it's highly recommended to upgrade. The release notes for Rayscaper 0.8.12 are here.
I use box stretching to target often. It suddenly stopped working. green arrow appears but none of the other indicators appear and nothing is clickable in the selected group. Any advice to resolve this?
We'll need more detail to understand what happens, may be the model, screenshots, ....
But how does SU read UDIMs? Separate maps? I know I read about this before with some other model you did but can't remember the workflow.
I did a quick recap in the thread about the Ferrari F2004, which was actually a pretty complex model.
Here's an extended overview of the full process I use to prepare the model for the cuts, the packing of the tiles and the final reload (including some tricks for unfolding flat strip throwing in a bit of Thrupaint and also to create an ID map straight in Sketchup). I'not sure which is the worst, if my english or my michrophone, but I hope it's itellegible enough. 🤣
