Hi there,


When I parent an object that drives the position of other objects via blendpose - to a path-driven object, the blendposing stops working? In the attached example, the sphere_object1 is blendpose driving the tube and little box y position. But then it is childed under the box_object1 (large box, which is a path-driven object to the line in the center of it) and the blendpose doesn't work any longer. Is this by design?

your file doesn't seem to contain anything

but from the description I guess you are driving your poses using local transforms of the sphere so if you move the sphere itself everything works, but if you parent it to something and move the parent, the local transform of the sphere will still stay the same, therefore your poses will stay the same as well

you can maybe extract world position of the sphere using Object CHOP and use that to drive your blendposes

Ok great thank you - I will try that. I have also fixed the file.

Thanks,Caesar

ok, looked at the file and that's indeed the problem

so just put Object CHOP in your BLENDPOSE_Chops network
point Target Object to your sphere
and choose Position and Rotation for Compute parm
then connect to first inputs of both of yours Blendpose CHOPs

Thank you - this worked perfectly.
