ok maybe to many questions at once

so lets start with copying existing renderdata

this code doesnt work (unfortunately)

  
import c4d   
from c4d import gui   
#Welcome to the world of Python   
  
  
def main() :   
    rd = doc.GetActiveRenderData()   
    doc.InsertRenderDataLast(rd)   
    c4d.EventAdd   
  
if __name__=='__main__':   
    main()

hints are highly welcome

thanks

Hi,

To copy a render data you have to call:

clone = rd.GetClone()

You can then insert the cloned render data. You cannot insert twice the same render data in a document.

To search the render datas you get the first render data with doc.GetFirstRenderData() and loop through them like objects in the document using GetNext(), GetDown() etc. Simply call rd.GetName() to get the name of a render data.

And to select a render data you have to set its active bit:

rd.SetBit(c4d.BIT_ACTIVERENDERDATA)

To delete a render data you can call rd.Remove(). This method is defined in GeListNode (one of the parents class of RenderData).

I#m sitting once again on this project... and unfortunately again got stuck

I managed to copy the renderdata (see above) and I managed to activate it.
there are two ways it needs to be activated:

- the name should be orange to indicate that i can change the values in this settings
- and the square left of the name should be white to indicate that these are the rendersettings that get used.

the square can just be active with one rendersettings set at a time
but several names can be activated(orange) simutaniously.

my problem:

i managed to copy the renderdata and to activate the name and the square.
unfortunately the name of the "old renderdata" is also still active(orange) so the old settings get changed (first in list) instead of the new once.

I tryed:

old_rd.DelBit(c4d.BIT_ACTIVERENDERDATA)
old_rd.DelBit(c4d.BIT_ACTIVE)
c4d.EventAdd()

but it didn#t work

thanks for help

Hi,

afaik using BaseDocument.SetActiveRenderData() automatically deactivates amy other renderdata.

Best,

Hi Niklas,

well yes and no the activation dot, square or what ever you call it, that indicated the renderdata that get used is exclusiv. so there can only be one renderdata checked at a time.

but you can select mor then one renderdata to change values (indicated by the orange rendersettingsname in the list.

here is a bit of code that shows the problem:
old code (ugly)... I will change the naming... of the definitions and variables

I see where's the problem. Even if we set the new active render data, the old active render data is still selected (its name is in orange color).

Here's how I changed your RDFindAndActivate() function:

def RDFindAndActivate(name) :
    myRD = doc.GetFirstRenderData()
    if myRD==None: return
    while myRD:
        if myRD.GetName()==name:
            doc.SetActiveRenderData(myRD)
            c4d.EventAdd()
        else:
            myRD.SetAllBits(2) # Reverse engineered with GetAllBits(), 2 is BIT_ACTIVE but we deactivate it so use the literal value
        myRD = GetNextObject(myRD)

Also just a note, c4d.EventAdd() wasn't called because you just forgot the parenthesis to actually call the method.

Hi Yannick,

thanks that works great.

one (hopefully) last questiion

if I use the RDFindAndDelete funktion with renderdata that has a child renderdata

  
    def GetNextRObject(obj) :   
        if obj==None: return None   
        if obj.GetDown() : return obj.GetDown()   
        while not obj.GetNext() and obj.GetUp() :   
            obj = obj.GetUp()   
        return obj.GetNext()

        myRD = doc.GetFirstRenderData()   
        if myRD==None: return   
        while myRD:   
            if myRD.GetName()==name:   
               myRD.Remove()   
               c4d.EventAdd()   
            myRD = GetNextRObject(myRD)

I gett a error message: Reference error: the object 'c4d.documents.RenderData' is not alive.

but the script still works as intended (at least I think so

This is because you deleted a render data that has a child render data. If you remove a parent render data, the children still references it but it's not alive anymore.
Before deleting a render data you have to make sure it has no children, removing or moving them.
