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.
