I was just thinking it might be useful to be able to mask normals by the direction they are facing. The most obvious versatile method that came to me was to mask normals facing the camera. With a tolerance or slope slider perhaps. I was thinking that is would be great for selecting upwards facing normals especially to paint on dust/snow or distributing objects or foliage. I’m sure there would be other ways to make use of it though. Perhaps there’s already a method and it’s slipping my mind, if so I apologize, but I’d appreciate a reminder.
You can use the Tool>Polygroups>Group Front feature to create a polygroup for the front facing polygons, and then use it for masking.
Then I suppose I can just growMask and shrinkMask mask in place of a tolerance slider. Seems obvious now, but things seem to fly right out my head every now and then. Hopefully that will remain in the memory banks for a while at least.
Well, there’s an angle tolerance slider for Group Front too.
Yeah, I found that… thank you for your help Marcus
