Help: particles will not move with their mesh. . .

Support Basics & Interface

Hello,

I am having a problem with a particle stream that will not move with a mesh. The mesh is parented to another body that I am animating and I want the particle stream to come along for the ride.

I am pretty sure there is a fix for this but not quite sure what it is.

Can anyone help?

Thanks

if it’s parented to an armature, or parented to something that is parented to an armature, than there’s no way to solve it.

Sorry, it’s not an armature. It is just a plain cylinder parented to a simple object.

Any other ideas?

should work then.

Can you post the blend file somewhere?
Email it to me if you can’t.

Actually, posting (or sending) might be more trouble than it is worth since it has proprietary information I would need to clip out.

Another posibility might be with the python script. I am driving the mesh with a datafile and a python script. If I take the script and the datafile away drive it with an IPO it works just fine. I can get the particles to update with the RecalcAll button but they are stuck in this new position until I hit RecalcAll again. Is there a way in python to do a “recalculation” before (or after) each frame?

Thanks

yes, you can call the recalc function with Python, but I really doubt that solves your problem.

I’ve had that problem already working with a script moving an object, and to make it compatible with the particles, you have to write the motion to an IPO.
