Select CAT layer via MaxScript?

[peter.spence]

I'm trying to wire 2 parameters via MaxScript. However, I have a few layers in the CAT Layer Manager. It seems that only the layer that is selected is then visible to the scripted parameters. So I'm trying to find a way to select the CAT Layer Manager layer in the script too.

Here's an example using a layer named Animation (with a Master object wiring to a Slave CAT object):

paramWire.connect $Master.rotation.controller[#X_Rotation] $Slave.transform.controller.LayerTrans.controller.Animation.controller.Rotation.controller[#Z_Rotation] "X_Rotation"

Everything works unless I have previously selected another layer in the CAT Layer Manager.

Any ideas?

Hi @peter.spence ,

to be able to select a CAT layer via Maxscript, it can be done by selecting it by its index ID.

For instance, with CAT parent selected

$<CAT parent>.numLayers

will return the numbers of layers.

$.<CAT parent>.selectedLayer

will return the index of the current selected layer.

$.<CAT parent>.selectedLayer=2 

will select the layer 2

I hope this can help,

That's great, thanks!

I'd been trying to do all sorts of MaxScript madness and completely over-complicating myself. Your help brought me back down to sanity, and solved the problem.
