lukpazera / mergeTransforms.py
Last active Apr 10, 2019
Using python TDSDK to merge two rotation transform items in MODO. The assumption is that the 2nd item is zero rotation one so effectively this removes zeroed rotation from an item.
View mergeTransforms.py
import modo
scene = modo.Scene()
i = scene.selected[0]
l = modo.LocatorSuperType(i)
rot = l.rotation
transformsStack = [xfrm for xfrm in l.transforms]

lukpazera / constraintRotOffset.py
Created Apr 3, 2019
This gist will calculate rotation offset angle values for a rotation constraint between two items in MODO.
View constraintRotOffset.py
""" This gist will calculate rotation offset angle values for a rotation constraint
between two items in MODO. It'll be exactly the same as setting up the constraint
with compensation turned on.
This code can be useed to update existing rotation constraint setup with new offset
without reapplying the constraint again.
The process is simple.
- get the world rotation matrix of the target and invert it.
- multiply source world rotation matrix by the inverted target matrix.

This is an example of a MODO config file that sets up a properties form that is only visible for an item that contains a given package. One more snatch from James O'Hare.

Script that prints out channel package for each channel of the first selected item.

for i in xrange(chanCount - 1, -1, -1):

lukpazera / cmdItemArg.py
Last active Jan 28, 2016
One way to pass item argument to command. Doing the same by using lx.eval and passing item ident is much easier though.
View cmdItemArg.py
import modo
item = modo.Scene().selected[0]
cmdSvc = lx.service.Command()
cmd = cmdSvc.Spawn(lx.symbol.iCTAG_NULL, 'texture.reference')
attr = lx.object.Attributes(cmd)
val = attr.Value(attr.Lookup("item"), True)
valRef = lx.object.ValueReference(val)
valRef.SetObject(item)
cmd.Execute(lx.symbol.fCMD_EXEC_DEFAULT)

Setting up dependencies between channels on a custom item requires implementing ChannelUI interface .
View chanUIDepend.cpp
/*

You can’t perform that action at this time.
