Importing 3D .obj, Geometry is altered/glitchy?

Hello!

I've been trying to 3D-model two tombstones in sketchup and then bring them into Adobe Dimensions CC, most of the textures look fine but some geometry is altered when imported. I've attached some screenshots, and I'm just wondering if there is a solution for this: Is Dimension more picky than other apps? I know that it's still quite new, should I just wait for it to become more stable and move onto something else? (just fyi: these are not real tombstones, just examples)

Take this tombstone for example, it has a distinct heart-shape on the top. When imported into adobe photoshop, Autodesk Maya or Unity the geometry is fine. Why is that?

This next one I expected some issues with, since its so complex: almost half is obscured, but the things that are visible look really good up close!

Do you have any advice for me? I'm quite familiar with dimension but this is the first time I've imported my own 3D .obj !

Have a nice day!

    The shortest answer I can give is, yes, it's still early and Dimensions import is still fairly naive.  We're actively working on supporting more .obj files with more specific types of geometry as well as new file formats.  We're talking closely with the Sketchup team and working on supporting that pipline closely.  You should see some significant improvements later this year.

    The basics is that .obj is a very open format.  Nearly everyone supports it but there's a lot of variation in the way it can be written.  More mature software have rules for all the special cases, but we don't have all that yet.  If you have another 3D application like Maya, or even Photoshop, try just importing the .obj into that software then re-exporting as .obj.  They might 'encode' it differently and then the new save will work.  I've found importing and exporting from Photoshop prior to importing to Dimension solves a lot of issues.

    Apologies for the work around!  We'll get more direct support directly in Dimension as we move forward!
