Hi, I did some more testing…

Things only go wrong with a linearCloner’s offset if:
_ any applied baseEffector has the visibility check turned on
_ has a mograph selection/weight tag
_ and if a linearCloner’s offset >= the smallest index of the selection
_ (so random has nothing to do with it

Hi @m_adam, thx for your input, it does reset the WeightManager, but doesn’t do the autoWeighting accordingly..

_First thing I noticed: a difference between int 64 & 32. Not sure if this might be a problem..
Reading the GET> AutoWeight…base.jointcount : <int64> “number of joints”
Reading the SET> AutoWeight…base.jointcount : <int32> “number of joints”

_After the WeightManager is being set (to 1 joint in my case), I can’t click on the “Calculate button” manually.
Nothing happens, unless I change the joint count manually to another number. So something in the update hasn’t been applied..
Note that reading the dict says <int32>, until manually changed, than is says <int64> again..

_I also tried wmgr.SetDirty(doc) / wmgr.Update(doc) / followed by another c4d.EventAdd().. Perhaps these need a different approach as well?
I tried to find something in the “maxon/frameworks” folders you linked to, but couldn’t find any info on how to tackle this issue.

So the current status is still that “default weighting” is applied.
If you can please help in the right direction, it would be greatly appreciated, tia, Jochem

Hi @m_magalhaes,

No there's still a problem, but for now it seams to be unsolvable.. It would be nice if C4D would allow for priority changes on the skin deformer - for polygon objects.

Hi @ferdinand, I was working on a similar topic, trying to change the prio of skin deformers to "after dynamics"... (didn't want to start a new thread, thx for replying anyway:)

Hmmm… some extra notes: Although it’s possible to change the priority of skin deformers - it’s of no use.
The documentation states that priorities only will be applied if the “Force” option under “Include” is turned on.
But that’s not for polygon objects.

So in my case, I wanted to set skin deformers after dynamics had been applied, but that’s a no-go.
The only alternative I found was to add an extra pythonTag (Gen.412), which updated all meshes.
This means that on render time all works well, but in the viewport it will still lag 1 frame

Hi, @m_magalhaes & the rest,
Joints & skins work a bit differently than setting priorities in the usual way..
Basically, only the first line changes @ the "declaration" of pd.

Hope this helps, Jochem

for item in items: # .. a list with objects or tags..
	# prioGeneric
	pd = item[c4d.EXPRESSION_PRIORITY]
	pd.SetPriorityValue(c4d.PRIORITYVALUE_MODE, 4) # 4 = Generators (as an example..)
	pd.SetPriorityValue(c4d.PRIORITYVALUE_PRIORITY, 412)
	item[c4d.EXPRESSION_PRIORITY] = pd

for j in joints: # .. a list with joints..
	# prioJoints
	pd = j[c4d.ID_CA_JOINT_OBJECT_PRIORITY]
	pd.SetPriorityValue(c4d.PRIORITYVALUE_MODE, 4)
	pd.SetPriorityValue(c4d.PRIORITYVALUE_PRIORITY, 413)
	j[c4d.ID_CA_JOINT_OBJECT_PRIORITY] = pd

for s in skins: # .. a list with skins..
	# prioSkins
	pd = s[c4d.ID_CA_SKIN_OBJECT_PRIORITY]
	pd.SetPriorityValue(c4d.PRIORITYVALUE_MODE, 4)
	pd.SetPriorityValue(c4d.PRIORITYVALUE_PRIORITY, 414)
	s[c4d.ID_CA_SKIN_OBJECT_PRIORITY] = pd

So, now we have a maxon.Int :}
Yes, the system is working - thx @m_adam
Consider it solved // more info in general on the maxon framework - especially on the python side - would we be welcome..

Super, thx a lot! Will check first thing in the morning :}

For a particular setup in R23/24, I’m trying to restrict the auto weighting to 1 joint - to avoid blending between weights (which will save me trouble down the line..).

Since R21 the “ID_CA_WEIGHT_MGR_AUTOWEIGHT_JOINTS” is removed so I can’t set it directly (see the simplified code below).

I tried to figure out a workaround, with no luck. My thought was that if I could read the autoweightDictonary, I could also set it.
The function “GetAutoWeightDictionary” needs a stringId (which is a maxon.Id, but that didn’t help me any further..)

So, the main question: How can I set the amount of Joints (to 1) when autoweighting?
And of course I don’t mean mannualy :} tia, Jochem

Below gets the focus back on the first tab of the pyTag (after other objects have been selected), but it only works with/after a button click..
Perhaps this might be of use.

            if userDataId == 1: # << just a button on the pyTag with ID 1
                ### do some function...
                # GET FOCUS BACK on the pyTags's 1st Tab:
                op.GetObject().SetBit(c4d.BIT_ACTIVE)
                op.SetBit(c4d.BIT_ACTIVE)

Yes, thx - the system works :}
