Unreal newbie here, I’m just trying to follow along with some learning videos (the exterior arch viz one specifically) using my own model (3DSMax & Vray).
I’m getting a lot of this error when exporting to datasmith: mesh name’s UV channel #1 contains degenerated triangles, this can cause issues in Unreal. It is recommended to properly unfold and flatten exported UV data.
Can anyone help me understand what this means? If I understand correctly, Datasmith uses max’s UVW channel 1 as Unreal’s UVW channel 0, so is the channel listed above related to the 3DSMax channel 1 or the Unreal Channel 1?
Also what’s the best solution to this? The error seems to mostly be cropping up on geo imported from the architect’s Revit models, which is no surprise, as they are a mess.
Would there be any harm in combining them all in to one mesh before unwrapping (channel 2!?)
Any help appreciated, go easy on me!
