Author Topic: Beginners Question - Missing Polygons  (Read 3867 times)

i am using substance painter for a day. so please excuse my ignorance.  :)
i watched some tutorials prior to installing it.

so i started with a very simple box in 3d max.
assigned a material, unwraped it and send it to substance painter.

the mesh and UV map looked ok.
i painted a bit and exported maps.. all fine so far.

then i added a little handle on the box in 3d max (all is one poly object).
unwraped it again, assigned a material to the box (ID 1) and one to the handle (ID2).





when i import that mesh into painter it look like this:





some of the polygons are assigned to the wrong texture sets.
of course when i only use one material on the object all looks fine.

i am not using a highres mesh on import.
i just want to try some basic stuff in substance painter. to get a feeling for the workflow.
so i just import a single low res mesh.

what i am doing wrong? :)
 
i guess my FBX export settings are not correct.
but i use the 3dmax to substance bridge, so the settings should be correct, not?

when i manually export as OBJ with faces as triangles, all looks fine:

HI,

Can you please post the max scene file? I will take a look.

Hi,

We can reproduce this issue as well. We are not sure what is causing the problem, but it's an issue with 3ds Max. We get the same result opening the exported FBX in other 3D programs. Our team is investigating the issue. As you mentioned, switching to editable mesh then to edit poly seems to fix the export.

any news? will this be fixed with the next release 2017.3?

you say it is a 3d max issue but i did not see this problem in other apps.

Hi,

I can check with the devs to see if I can get more info. At this time, I don't have any updates.
