Move UV Map channel 1 to 10 of maps on entire scene

[3LP]

Hi guys.

I'd like to be able to move all the maps channels from a scene from 1 to 10 in the materials.
Currently I'm using Zorb and it's working pretty well, but I was just wondering if anybody had another approach for this.
Maybe a script that would read through all the maps and move them?

Thanks

If you want to change every bitmap in the scene then you can use:

for b in getClassInstances bitmapTexture do b.coords.mapChannel = 10

It is completely indiscriminate however and will change the channel of bitmaps used in modifiers etc.

If you only want to change maps used in scene materials use:

for b in getClassInstances bitmapTexture target:sceneMaterials do b.coords.mapChannel = 10

Nice one.

This is only working for the bitmap maps though.
I was think of something that could work on any map type in max : noise, tile, bercon, checker, etc.
Is there a way to access this .coords.mapChannel for all the maps type or do we have to manually specify each map type?

Thanks!

Yes, but unfortunately they all use slightly different ways of setting the map channel so the code is a bit longer.

(
	local mc = 10
	for b in getClassInstances StandardUVGen target:sceneMaterials do
	(
		b.mapping = 0 --delete if not required
		b.mappingType = 0 --delete if not required
		b.mapChannel = mc
	)
	for b in getClassInstances StandardXYZGen target:sceneMaterials do
	(
		b.coordType = 2 --delete if not required
		b.mapChannel = mc
	)
	for b in getClassInstances berconTile target:sceneMaterials do
	(
		b.xyz_map = 0 --delete if not required
		b.xyz_chan = mc
	)
)

I've also included lines to set the coords to use the specific map channel. If you don't need these just delete them.

Dude, you rock!
Doesn't work for the bercon noise, but I guess I can try to find out what it should be

At the same time, I'm using this code to apply a Unwrap to each selected object to move the UV map from 1 to 10.
Would you see any other way to write this that would be better?
Works well but we never know you'd have a idea

theObjs = selection as array
clearSelection()
max modify mode


for obj in theObjs do
(
    select obj
    modPanel.setCurrentObject obj.baseObject
    modPanel.addModToSelection (Unwrap_UVW ()) ui:off
    obj.modifiers[#unwrap_uvw].unwrap.setMapChannel 10
    obj.modifiers[#unwrap_uvw].unwrap.move ()
    --hide obj
)

I use this, had it custom made by a friend - https://www.dropbox.com/s/ztay9nxrfo...k_v003.ms?dl=0

It has an option for shuffling UV's from one channel to another. Along with several other features.

If you select all your objects, choose source UV, 1, and target UV 10. It should do the trick.

Hey,
Thanks for this but it seems not to be working for me
I did source uv and target uv and "shuffle UV", not sure what I do wrong.

Here is my test scene :

Does it work for all of those maps for you?

Cheers

looks like it's working for me.. you need to drop a uvw unwrap down if you want to view (punch in ch10 and click 'abandon' to see that ch10 has the same UVs as ch1). Basically it's moving the UV's from 1 to 10, so ch1 will stay the same and ch10 is getting updated to match. I think you applied it twice to these teapots

[3LP]

aaahhhh right!
I though you spoke about moving uv map in the materials, sorry mate.

Yes then I guess it's doing it the same way as my script about, but great to have a UI

Cheers!
