Rastering problem with new 3D tools.
I've been testing out the new 3D tools and materials and for one day I didn't have an issue. (I've been using it mostly for creating 3D text). Now, out of nowhere, my 3D models lost their quality and the shadow casted is in an even lower quality — as if they're not vectors like before.
I tried adjusting the raster settings — I am working on a RGB file with 300dpi quality. I changed the quality to 300dpi in Document Raster Effects Settings as well, and in the general preferences.
I'm so desperate I even reinstalled Illustrator and restarted my device.
How can I get my 3D models back to vector?
Here how it looks now:
