Dear all,

I am not sure what is that called? I want to highlight a certain parts of my mesh(es). Just like when you manipulate a mesh in 3dsmax, you may do a marquee selection, and some parts or objects get highlighted and you can edit them or move them around etc, it's not the gizmo because gizmos are one-point stuff, you know I want to have things like you have in Photoshop (the brushes), when you get a large circle that you can do a lot of painting all at once. Any ideas?

thanks

Jack

I am not a 3dsmax user so I don't know exactly the technique you are specifying, but there is some discussion of similar here:

You may decide to use a different solution depending on whether you are doing a single click or marquee, or if you want to use a continuous brush, where performance of some of the methods could become more of a concern. Note with some of the screen space techniques there could potentially be issues of triangles smaller than a pixel not being selected.

As well as basing your brush on screen space, you could also precalculate the connectivity of the mesh and have the brush 3D.
