Change the output dimensions or resolution using VR Comp Editor

[jerometave]

I'm trying to use VR Comp Editor to create a 360 Panorama from a camera I placed in a 3d scene.

It works perfectly in creating the equirectangular image, but the output is always set to 4096px wide, regardless of the comp width I type in while creating the VR Comp 3D edit.

When I go into the composition settings and type in my desired dimensions (7200x12800 wide), it scales up the footage, but in a way that pixelates it. The graphics I'm working with is Trapcode Form (obj) applied to a solid layer.

I've tried digging around and changing the dimensions of different comps, but nothing seems to work.
