Complexity of imported obj files

[cehweh]

Hi everyone, I´d like to know if there´s a simple way to make imported files less complex.

Here´s the problem: I am using the ESKO Studio Plugin for Adobe Illustrator to export "folded" objekts like displays made of cardboard as an .U3D file to open these in Photoshop. Then I export my 3D layer as an .OBJ File in order to open/import this file in Adobe Dimension. The pitty is, that already my 3D layer in PS has so many seperate texture files included, that the final work in Dimension gets really slow, especially when I duplicate these objects. I often have to save my work in order not to crash the application and sometimes, when I try to re-open saved files, I get an error message that something went wrong and dimension wont work properly. Even after restarts of the app and the system some of the .dn files can´t be opened again. Using DN 3.3 on mac high sierra/mojave. Any tips to "flatten/merge" all these textures already in PS to make this process less complex? I already try to generate UVs in PS, but this does not really help und the exported 3D layer as an .OBJ has a much bigger file size, too. Anybody else having experience with generating less complex .OBJ files. Maybe even a tip with exporting the original 3D file out of Illustrator with the ESKO plugin. Thanks in advance for response and/or help.

as in front, beval, extrustion, back etc? fix is to select your model in Dimension and pick a new material... this auto-redoes the textures

it would really help to have one of these Obj files if you can share so we can give tips but yes what you discribe is normal crash caused by system running out of Ram and dropping file size should help

Thanks for your reply. Here´s a .DN file with the imported .OBJ from PS. Hope this helps. Screenshot shows all the material/textures that came with it.

I am not familar with ESKO Studio Plugin. Is it possible to merge layers in Illustrator.and increase or decrease layers amount?

to share a .Dn file on Adobe cloud you must zip it first... note only .zip will work not 7z or any of the newer file types

or you can use a 3rd party share system
