From some updates ago, the GLB files aren't displayed and rendered correctly in Dimension. The solids get some mistakes in their surfaces as you can see in the picture. With other types of 3D, like OBJ, they are displayed and rendered correctly.
I tried other GLB files with different solid geometries, and the problem happens too, also in different computers with different graphics cards.
I cannot add the Dimension file to this post, I get this message:
Is these GLB file have been created by you in any other app or was downloaded?
Created by me in Inventor. But until a few months ago they are fine and now I get these rendering errors. If I export the part in other formats like OBJ they look fine. Open the GLB file in other software are fine too. So I think the problem is in Adobe Dimension.
If I import the Dimension project to Stager the object remains with the same problem. If I create a new project in Stager and I import the GLB file it fits perfect. So, is something with the use of GLB files in dimension.
I tried an earlier version (3.4.7), and the same GLB file has been imported and rendered perfectly.
The same occurs with other GLB files.
From my side I prefer Stager. For me its better than Dimension.
Maybe you're right, but Dimension it's included in my Adobe Creative Cloud Plan. To have Stage I need to add an additional payment more or less the same as I pay now.
