Short description of error
UDIM: filling a secondary tile with a generated image before you fill the first tile wont actually fill the tile... you have to fill the first tile to actually see anything...
Exact steps for others to reproduce the error
- Open file
- In the Image Editor > Image Tab (sidebar) > UDIM Tiles panel you should see two tiles [1001 and 1002]
- both tiles are not filled yet
- select the 1002 tile (should be selected already)
- execute the Fill Tile operator
- UDIM token is added to the tile, but it is not filled
This was already mentioned in T72487: UDIMs: Loss of texture information after saving., but reporting here separately as requested by @Lukas Stockner (lukasstockner97).
Note this already had an answer there:
