Skeets, one problem with the one sided mane...It only works in CAS...Any idea why? or am I doing something wrong?
When I was working with manes this was due to the mesh not being updated for Medium/Low res. Are you using Med or Low graphics? If so, Skeets may have to update the mane.
Try what Equestriad said first, if it still doesn't work the above may be the issue. Not sure if Skeets updated the Med and Low mesh. Just checked and only the Very High mesh is updated. If you're running anything less than High/Very high graphics, that's the problem.
Lakeside Ranch: Can you update the file to incorporate the mesh into the Med/Low settings? That way it'll work no matter the graphics settings (one of my beginner mistakes).
