Hi,
For UDIMs workflows there are a lot of limitation in Unreal. Opacity does not support Virtual Textures and therefore UDIMs, so if you have UDIMs you cannot have a proper opacity mask for it; which is a massive limitation.
Same goes if you want to apply displacement through the Modelling Editor tool.
UDIMs is an efficient and time-saving workflow and needed to have high quality details.
There should be at the least the option to use it with these cases.
Please could we introduce this feature,
Best regards,
Doriana
