No need to change the display driver : Best solution to date in 2023, work in previous Max versions too, : * Create your Material * Inside the texture channel add a "composite map" * Than add inside the composite map a bitmap with filtering set to none
Confirmed it works in latest version of Max. Not true unfiltered nearest-neighbor filtering though. If you're willing to change the display driver, you can get pure point sampling, and no need for Composite:
