Hi everyone

Anyone know if it's possible to add a startup script in R20 like in previous versions?

The old method was adding a python_init.py file to the directory:

Cinema 4D RXX_XXXXXXX>prefs>python

The python directory no longer exists so not sure where to put it.

Thanks!

Hi Maxon team,

I'm creating a python ObjectData plugin which uses handles and I'm experiencing some strange behaviour.

I can transform the object and then move the handles without issue in any viewport as expected. The issue arises if I have multiple views. So, say I'm using a 2 view setup, if I transform the object in one viewport and immediately move the handle in the other viewport, sometimes it triggers erratic behavior where the handle position appears to be flickering between it's expected position and somewhere in another plane. Once the behaviour is triggered it seems to remain.

Some anectodal notes:

Closing and reopening the file makes the issue dissapear
Deleting the object and creating a new one and the issue remains

Here's a video showing the flickering (starts about 19 seconds) :

Here's my handles code in it's simplest form:

    def GetHandleCount(self, op):
        return 1

    def GetHandle(self, op, i, info):

        info.position  = op[c4d.ID_USERDATA,1 ] # this is a simplified example so using UD instead of a parameter
        info.type      = c4d.HANDLECONSTRAINTTYPE_FREE

    def SetHandle(self, op, i, p, info):
        op[c4d.ID_USERDATA,1 ] = p

Any ideas to what's going on / what I'm doing wrong would be greatly appreciated.

Thanks,

Hi Ferdinand,

Thanks for the in depth response. The support procedures are new to me and I will be sure to go through them when making future support requests.

I have taken your advice and for now moved towards a system using MoveHandle. The above example and your c++ code example earlier in the thread has been super useful in implementing this. I think we now have a solid functioning set of handles in all viewports and using ProjectPointOnPlane along with some camera space calculations.

Big thanks,

Adam
