Overdriving Max

I don’t know why you’d really want to but I’ve seen a few people getting annoyed at the Render Size limit in max of 32768 x 32768, this limit in Max is not because Max can’t render any larger, it’s just because the spinner you use to set your render size has an internal range limit of 1-32768. You can actually force max to render bigger by over-driving this value using maxscript.

Close your Render Scene Dialog

Put this into your maxscript listener

RenderWidth = 100000

Open up your Render Scene Dialog again….

It will read 32768, but if you press render you’ll get a 100000px wide render.

Beware memory usage, but if you’re just rendering something in scanline, or using Deadline to Tile Render then you can use this to get a bigger render.


This trick can often work with other parts of max and other renderers where the UI will restrict the value but you can over-drive the value, for example it may be a sampling setting or subdivision setting that is old and limited in the UI.

A very practical usage I found of this lately was to make the Normalize_Spline segment length less than 1.0, the UI is limited to 1.0 but via maxscript you can set it to much smaller.

    Its also good for changing some of the values in the graphite tools. Its really limiting depending on which units you are working in…so its nice to be able to change them to lower values in maxscript as well.
