I am trying to import an alembic file with animation into ue4. The problem is when I import it the mesh becomes very distorted.
This is a screenshot of the mesh in cd4 (it’s a book in case the lack of materials makes it hard to see):
This is how it looks in ue4
As you can see the pages are outside the book and part of the books cover is missing. I tried all the import/export options I can think of.
For export I’ve tried both Ogawa, and the legacy HDF5. On import I tried the 3ds max and maya preset. I also tried to export the file out of 3ds max and use these presets but the result is the same.
Any ideas what is causing this behavior?
I am facing the same problem!
Same here, read that someone has reimportet and exportet it with 3ds max, that could fix it
After hours of trying every setting possible, I finally figured out what caused my imported Alembic meshes to appear distorted.
My mesh was very small, and apparently there’s this setting called ‘compressed position precision’ under ‘geometry cache’. And this basically simplified all the vertices’ position to the nearest grid-like position.
So, either scale up your Alembic when exporting. Or lower this compressed position precision value to the lowest it can go.
Not sure if this is the exact same issue you have, but it’s worth considering!
