Datasmith UV error

[Masterythepua]

I am using 3ds max and I want to export my scene to UE4 using datasmith. But I take these error for almost every asset in my scene : UV channel #1 contains degenerated triangles, this can cause issues in Unreal. It is recommended to properly unfold and flatten exported UV data. I try to unfold and flatten the image but it doesn't work. I am also confused because If i import the same asset with fbx directly to ue4 everything works fine but if i imported it to 3ds max and then convert it to datasmith or even fbx I still get this error... Any suggestions?

can we get the 3ds max file, we can have a look. send an archive containing only one object to pierrefelix.breton@epicgames.com (i don't want a large project, just one object that has the problem).

Any follow-up to this problem? I'm experiencing the same issue.

This!
The very same geometry get exported just fine from Sketchup's Datasmith, but from Max Datasmith fails with "contains degenerated triangles" pop-up.
Pierre, I sent you both skp and max files. Please take a look.

To degenerate triangles use Prooptimizer modifier in 3ds max.

I am having the exact same issue here. No matter how many objects I remove from my scenes, I always get a massive amount of "...contains degenerated triangles...properly unfold and flatten..." errors. I get these errors on every last 3dsMax project that I have tried exporting to Datasmith (4 different projects now - all created in 3dsMax 2020). And, needless to say, when trying to import these datasmith files into UE it simply crashes.

This is VERY frustrating, as I have been wanting for years to transition into UE for architectural visualizations; figuring that now would be a good time to do so, considering the promise of (virtually) trouble-free importing of 3dsMax/Vray content with Datasmith. But I'm consistently running into a stone wall at the most basic step in the process - file export.

I have found that even virgin, un-modified standard primitives (cylinders and such) produce the exact same degenerated triangles error. This is absolutely maddening. Surely I needn't apply a pro-optimize modifier to each and every object in all my scenes to get Datasmith to work...
