Importing 3d assets

Hello! I’m trying to find out which file type is best for uploading 3d assets into Shapr…primarily, I’d like to import some plants/trees/bushes etc…there are plenty of sites that have free or cheaper “kits” of greenery but are usually in OBJ file format, etc.
Can anyone help me with this?

  1. What file format/s support 3d asset upload
  2. Trusted website/s for plants/bushes/etc
    Thanks in advance!!!:see_no_evil::+1:t3:
