VR Converter Tools in Motion

Hello,

I am a planetarium producer and I create full dome immersive media. I currently composite in After Effects due to its VR toolset. I would really like to make the move to Motion, but from what I can see there isn't a suite of VR converter tools that lets me format media for a 1:1 fisheye full dome image. For example, in After Effects I can load a 360 degree VR equirectangular panorama into a composition. I can then convert that from equirectangular to fisheye (full dome) and vise versa. The tools also let me re-orient the "camera" view in pitch, roll, yaw. I can also transform flat images into spherical. Is there any way to do this is Motion? After Effects is the last element that keeps me from being able to jump off the Adobe subscription treadmill.

I have attached a couple of images. One is the vr tool applet in AE and the other is an example of a full dome fisheye image that is the end result.

Thanks,

Troy
