Blender: exploded UV's on .obj export...

ironbearxl

When I export an obj from Blender into any other package my UV's are exploded into seperate faces. Is there an export option i'm missing?

CheapAlert

That's odd, it shouldn't do that as that never happened to me. Can't be Blender's end :S

2.45?

ironbearxl

Yup, 2.45

I must have some export option checked that's causing it?

What does the output. obj look like for a uv mapped cube? (just click new uvs in F9 editing context and export :P)

The output .obj is fine, it's only the uv's that are split into faces (elements). I can weld/merge them with a tolerance of 0.01, which works too.

I posted on the Blender forum a few months ago, and the issue is now fixed in 2.46

So... it turns out it could be at Blenders end?

I wish importing and exporting would go perfectly with everything all the time, and sadly, that's not often the case. I thought I heard something was changed about the Blender file dialog. Was that in 2.46, and --dare I ask-- is it less terrible now?
There's not a way to use a more standard one, is there?

There were some issues associated with doing a direct import and export of meshes (using Blender as a simple converter), usually OBJ files, where nothing was done to the objects whilst it was in Blender; not sure what goes on behind the scenes but it *would* do funny things like that (always has in fact, much like any other 3D app AFAIK).

There is talk of bigger changes for 2.50, not looked at 2.46 myself yet but I wouldn't be expecting too much of a change just yet on that one.

2.5 should have the interface upgrades your looking for. In addition to a new file browser and redoing all the buttons and menu layouts, they are also planning to add better Python/UI integration so perhaps there will soon be drop-in scripts to customize the interface any way you want.
