No, Plus is compatible with all major 3D software – all in one subscription! For ease of use, we’ve created material importers specifically for C4D, Blender, Houdini, and Unreal Engine. For other software, please download any assets from their Online Library. Their textures are industry-standard PBR, their HDRIs are also standard EXR files, and their models are standard FBX files. All of the Greyscalegorilla assets will work anywhere PBR, EXR, and FBX files are supported.
