Wondering why the vents are showing up as Red on my model. Also, wondering why symmetry on X is showing up on the left rather than the right side of my model.
Any assistance would be greatly appreciated!
Update: I'm now having issues with Retopoflow install after trying to update my version of Retopoflow.
I am operating on Blender version 3.1.2 and downloaded software version 3.3.0 as per documentation.
Hi! I believe the following should solve all your questions:
Red vertices just show the borders of your mesh, so you can tell where a hole is. You can turn this off in Viewport Display / Non-manifold Outline.
Symmetry is on the left either because your model is rotated or its orientation is backwards.

For the install issue, try using RetopoFlow 3.2.9 and let me know if that works! I'll update the documentation if it's mistaken.
