Hi @Anonymous
Thanks for the following up . I always like it when the original poster puts some effort into trying to clarify the issue and respond to questions. It shows a collaborative attitude.👍
OK, to troubleshoot this, let's separate and try to eliminate the following potential sources of error:
1. Drag and drop functionality with different versions of Max and different computer configurations (which have been reported). I could not tell from your response whether you have already tried not using Drag and Drop for import, so please bear with me in the suggested tests below.
2. Your home computer configuration (software and hardware) vs the configuration you had no problems with in school. ( Was it the same version of Windows, the same Graphics Card, both had Max 2020.3, etc? )
3. Differences in downloading different file formats from various sites and the import dialogue settings that you might use to import the downloaded file format.
To test the above, try the following;
Test A (basic local machine Max installation functionality). Create a simple object in max with anything you like, a box, a sphere or whatever. Covert it to an editable poly, UV unwrap it (nothing fancy, just flatten it out) and apply a texture. Save the max file and then export it as an .fbx. Reset max and then import this .fbx via the import dialogue with the default settings (i.e., Do Not Use Drag and Drop). Capture a screenshot of the result and describe any differences from the original scene.
Test B (Local Drag & Drop import functionality). If Test A produced the expected result, then reset your Max scene and this time, drag and drop the same .fbx into the viewport and again describe what happens. If Test A worked but Test B did not, then Drag & Drop has some issues with your configuration.
Test C. If you haven't already tried this, use the import dialogue to import one of the separately downloaded models that you could not import via drag and drop.
Test D. Post a .zip of a file (Not all file types can be posted here, so to be safe, make it a .zip) that you have downloaded that you were unable to import into max on your computer and I will check to see if I can import it and see if there are any issues with it.
Test E: Attached is a .skp file (in .zip format) of a circuit board I downloaded from Google Warehouse in Sketchup 2019 format and was able to import without any difficulty. Try to first import it via the import dialogue and then via drag and drop and advise results.
