Thank you, Dan. What you gave me (tweaked) is working perfectly. Here are some test screens of what I’m doing. It’s more complex than I described as I tried to keep the description simple. It is VR180 animation of three “ships” flying through clouds and around a larger “mothership”. The center ship (and the stereo cameras) is following a 3D path (the parent), but the wingman ships needed the offset, and they also need to bank together in formation (rotating the master Null causes them to bank). The MIR ship objects (as well as the Particular trails) are using that code to connect to individual Nulls with the offset. Probably not explained very well, but it’s all working great (so far).

This is all in a custom VR180 stereo camera rig designed for VR headsets.

Thanks again for your help.

Some success. I tried some half-educated guesses (and more digging in your website) and tried:

L = thisComp.layer(“Null 1”), anchorPoint;

L.toWorld(L.position)

This seems to work. Don’t know exactly why – yet.

Thank you, Dan. My script knowledge is rudimentary, so I’m working to figure out how that script works and what it is acting on.

It picks up the position of Null 1 (the child), but not the anchor point offset that I have put into Null 1. So essentially it is picking up the position of the original parent.

Sorry about the links. I’m new to Creative Cow. These should work now.

I’ve tried the Skybox thing, but it leaves lines in the stitching with Trapcode stuff. I guess flares and glows have issues at the camera edge and that creates the problems. I don’t know if others have that same issue.

So I’ve been experimenting with a “fake” stereo rig by rendering each eye separately and combining in a new comp. Here are the VR180 results on YouTube. You heed a headset for best results. I’m using an Oculus Rift S.

These are done with Particular. The AE camera is not a real rectilinear and does create some distortion at the very top and bottom (look up and look down).

Thanks for the reply. I’ve been look at RAM allocation, but it doesn’t seem to affect Cache usage. Any thoughts on reducing Cache space to force more RAM use? Thanks for the help.
