I had trouble getting the original 3DS models loaded into the latest (Windows) version of Photoshop CC (v21.2.5), Photoshop would simply crash 9/10 times trying to import them.
So I exported them all into Collada (.dae) format as well as PSD format. Now they open every time for me without a hitch. I'm uploading it here hoping it helps anyone else in the same boat I was in.
This also allows you to easily import them into Blender without needing any additional addons.
The PSDs have been saved for maximum compatibility. The archive is 2.16 MB and requires 7z to extract, disk space upon extraction is 66.5 MB.
Each model is provided in the following formats: 3DS, DAE, and PSD
Hope its okay to post in this old topic, i thought it would be appropiate because i just figured out how to use this 3d function in Photoshop and i think its pretty cool so i uploaded me working on a texture in the 3d function. I only did not figure out how to work on the different parts yet, it seems to use 1 image for all sections of the model that i cant seem to change. maybe it helps other people. you can basicly use all functions and see your results directly.
