Export to OBJ partially fails for MeshPart and UnionOperation


#1

This is a very strange bug, very dodgy.

When exporting certain Unions or MeshParts, the objects that get exported are always a bit dodgy. Here’s an example.

The original object in-game:

The exported object in blender:

There’s not much more to this. It’s very inconsistent.

FOLLOWUP: It seems I have to select each part type separately, and this is by ClassName, not the root type. I had to individually select my Parts, export, individually select my UnionOperations and export, and individually select my MeshParts and export.


#2

Are you exporting a model or is that original object just one piece? Sometimes I’ve noticed it only partially exports what’s in a model, but I can usually get it to work after trying it 2-3 times. Has been going on as long as I can remember, and I’m not sure why that is.


#3

If you’re exporting a model, usually I fix it by opening the model in explorer and then selecting everything inside with shift+click, then export since it seems with the model function it doesn’t always grab the other BaseParts. It’s not a 100% fix, but it does work more often than not.


#4

I’ll have a look.


#5

Selecting only BasePart was able to resolve this issue. Thanks. Ideally Roblox can resolve this soon.

EDIT: It’s not exporting my MeshParts now, for some reason. I’ll followup soon with details on how to get all of this working so I can get a proper repro in.

FOLLOWUP: It seems I have to select each part type separately, and this is by ClassName, not the root type. I had to individually select my Parts, export, individually select my UnionOperations and export, and individually select my MeshParts and export.


#6

Glad you found out what was going on. I’ll remember that next time, if it isn’t fixed by then, as this is quite annoying. I always thought it was just a problem with model’s not selecting all the pieces within it, especially a model within a model. Perhaps you could test that out as well?


#7

This is still an issue.
