Meshes with high polygon counts export incorrectly #4

Closed Lasercar closed 1 month ago

Lasercar commented 1 year ago

Same problem as the psk/psa exporter addon, exports above a set limit of verts and triangles get artifacts and lose parts of the mesh.

Edit: I got confused with both this new project and the older one (Yet I somehow still made the issue here?). Anyway, the issue title still applies, but rather than stopping at a set limit (like the old version), it messes up the triangles after a certain point: Capture I'm updating this model import to replace the auto smoothing and giving it's original smoothing/sharp edges, so you might not be able to replicate this on your end with the model from the addon.

@Lasercar could you post the blend file that you used to produce the bug?

Lasercar commented 1 year ago

@cmbasnett Sure. Unreal will take its sweet time to import it though, the exported file is 23MB. HPScorpion.zip

It appears that there are hard limits on the amount of elements (i.e., vertices, triangles etc.) allowed in an ASE export when importing into Unreal. This is not technically a bug with the exporter, since the ASE file format doesn't specify any of these limitations, and the bug is a result of a deficiency in the Unreal engine where it doesn't enforce its own limitations.

If I can be given a list of the actual element limitations for the format in Unreal, I can code in a warning that the mesh will not import correctly into Unreal engine.

Going to close this since this is not actually an issue with the exporter, but of handling within the engine importer.
