Let’s make the preview pretty!
I think the default material preview looks really ugly in 3ds max and it doesn’t give you a realistic render to what I would render out. So why not just change it to something that looks a lot nicer. I am using some vray stuff in the file you can download so if you don’t have vray just change the rectangle vray light and the dome light.
Just download the files and place it somewhere on your harddrive. Open up the custom obj file and give the vray dome an hdri image then just save the file.
In the options -> options.. just select the custom background in the “custom background” section. And last but not least, in the Custom sample object place your custom obj file and check the checkbox.
The background PSD includes some different patters such as checker (large and small), stripes (large and small) and diagonal stripes (large and small).
