Max script, how to see uv channels

codyaq2 · Mar 2012

Hey

I have a few hundred objects in my scene, and i want to find out what the highest UV Channel number there is in a selection of objects. I know you can look in channel info, but when you have a lot of objects, it gets messy to find it.

Cheers

Cody

function HighestUVChannel = (
	ch = 0
	for o in $* where o.modifiers[#Unwrap_UVW] != undefined do (
		if o.modifiers[#Unwrap_UVW].getMapChannel() > ch then (
			ch = o.modifiers[#Unwrap_UVW].getMapChannel()
		)
	)
	ch
)

HighestUVChannel() will then return the greatest UV Channel number in the scene.

Thanks, but it doesn't seem to return a value, only returns HighestUVChannel().

HighestUVChannel()

Execute that after you execute the example code to get the number you are looking for.

Execute

HighestUVChannel()

to get your result.
Alternatively, run:

function HighestUVChannel = (
	ch = 0
	obj
	for o in $* where o.modifiers[#Unwrap_UVW] != undefined do (
		if o.modifiers[#Unwrap_UVW].getMapChannel() > ch then (
			ch = o.modifiers[#Unwrap_UVW].getMapChannel()
			obj = o.name
		)
	)
	ch
	format "% has % channels.\n" obj ch
)
HighestUVChannel()
