I have a model with UDIMs, and during the texture import, it created two textures instead of the expected one (1001, 1002). I am looking for the proper method to publish models with UDIMs in FAB.
Virtual texture support has to be enabled in project setting and the textures have to be properly named according to UDIM naming conventions which would be .1001 at the end of texture name for first texture and .1002 for second texture and etc…
Alternatively you use paid plugin like UDIM Editor plugin on Fab which allows you to create UDIMs inside UE.
