- It's not possible to make wrapping work correctly for lower mip levels, depending on the sizes of the VTs in the stack - Now UDIMs that are smaller than stack dimensions will just map the lowest resolution mip to out-of-bounds addresses - Entire stack will continue to wrap, based on the stack dimensions - End result is UDIM wrapping should no longer by relied on #rb none #jira none [CL 16184868 by Ben Ingram in ue5-main branch]
