OBJ export problem in AC 21

[Anonymous]

Hello,
it looks like the wavefront (.obj) export is buggy in AC 21.
The objects don't keep their material definition.
I think the problem lies in that the material name in the .obj file can be different that the corresponding ones in the .mtl file.
Hope you can fix that soon GS.
Regards

Any news on that?
Anyone has tested the new international version?

Obj is (was) the best format to export to other 3d softs, the only one that kept correct geometry materials and uvwMapping. Maybe it is old but still the best so far.
Plus it was the fastest, which is important for big projects.

DAE export could be interesting if it was able to keep names of materials, but that is not the case so long.

Tried 22 and no luck...whazzup?

FBX /twinmotion export) kind of works great aside from the fact that the model opens rotated 180 degrees around the x-axis in sketchfab...that is upside down.

Hi,

The issue with obj file export, that the materials got messed up should be fixed in AC21 60xx and AC22 30xx.

Did you find that it still messes the materials up for you the same way in the new version?
Or do you experience a new error?

I tried AC22 SWE full 4018. No textures on the surfaces.

Hello Again,

I tried AC22 INT on W10. I opened the exported OBJ file with the default Microsoft 3D Viewer application, and it seems to be fine for me...

• What application are you using for opening the obj file? (maybe that application can't display materials at all?)
• What does the result look like for you?

AC22 SWE full. Latest update. I use Sketchfab for viewing. When I export obj I get the concrete material but not the brick (both png) I zipped the obj+mtl+texture folder into one zipfile and in Sketchfab I can manually relink the textures but that's not interesting. When I export as fbx textures are fine but the model is rotated.

I haven't tested this but I am wondering if when saving as OBJ, is it using the wall surface override rather than the building material, or maybe it is the other way and it is using the building material rather than the surface override.
I am wondering it it is using one or the other regardless of how the wall is actually set to display in Archicad.

Sherlock Kelly, you're right. It's only the override surface that exports applied to the element.
.fbx does the job as expected (WYSIWYG) apart from the rotation (which I can fix in Sketchfab).

Thus both obj and fbx are flawed (at least with Sketchfab). Fbx is the better of the two...
