Persona Grid and Origin visualization

Currently, we can enable the grid within persona, but it is REALLY hard to see. It’s a really light gray line which fades out quickly. There is no editor setting to customize the color of the grid lines.

I also want to be able to see the X/Y/Z axes, so that I can see where my animation is relative to the origin at each frame. This is helpful for root motion and non-root motion related things, and to make sure that the animation was imported correctly into the editor.
