Ok, I ran into the issue of polling the BatchRender.IsRendering. I don't have the python skills to do multi-threading to check when a render is complete. I was able to hack in a time.sleep function but it is very problematic for longer renders and crashes a lot.
Instead I went the route of Takes though Take are a bit cumbersome to setup but it is working nicely. I'll post the code here for anyone looking to do something similiar. I can just RenderAllTakes command and get each object rendered with its name using a $Take render token.
def main(): doc = c4d.documents.GetActiveDocument() inEx = op[c4d.ID_USERDATA,4] # In/Exclude User Data for i in range(0 , op[c4d.ID_USERDATA,4].GetObjectCount()): #Iterate through each shot based on our shot slider in user data activeObj = inEx.ObjectFromIndex(doc, i) #deterimine which object is active if op[c4d.ID_USERDATA,1] == i: activeObj[c4d.ID_BASEOBJECT_VISIBILITY_EDITOR] = False #turn visibility On activeObj[c4d.ID_BASEOBJECT_VISIBILITY_RENDER] = False render_filename = inEx.ObjectFromIndex(doc, i).GetName() #Gets the name of the currently active object op[c4d.ID_USERDATA,5] = render_filename else: activeObj[c4d.ID_BASEOBJECT_VISIBILITY_EDITOR] = True #turn visibility Off activeObj[c4d.ID_BASEOBJECT_VISIBILITY_RENDER] = True c4d.EventAdd() ################ SEND ALL def BuildTakes(): #Sequencer() takedata = doc.GetTakeData() obj = doc.GetActiveObject() #print( Description.GetParameterI(op[c4d.ID_USERDATA,1], ar=None)) inEx = op[c4d.ID_USERDATA,4] # In/Exclude User Data for i in range(0,op[c4d.ID_USERDATA,4].GetObjectCount()): #Sequencer() take = takedata.AddTake(inEx.ObjectFromIndex(doc, i).GetName(), None, None) take.FindOrAddOverrideParam(takedata, obj , c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA, c4d.DTYPE_SUBCONTAINER, 1),c4d.DescLevel(1)), i , backupValue=None, deleteAnim=False) take.FindOrAddOverrideParam(takedata, inEx.ObjectFromIndex(doc, i), c4d.ID_BASEOBJECT_VISIBILITY_EDITOR, False, backupValue=None, deleteAnim=False) take.FindOrAddOverrideParam(takedata, inEx.ObjectFromIndex(doc, i), c4d.ID_BASEOBJECT_VISIBILITY_RENDER, False, backupValue=None, deleteAnim=False) #op[c4d.ID_USERDATA,1] = 0 #Sequencer() #c4d.MSG_DESCRIPTION_CHECKUPDATE #Sequencer() #c4d.EventAdd() def ClearTakes(): tk = doc.GetTakeData() tk.ResetSystem()
