Is it possible to draw a voi directly on a 3d render?
Hi. I really love your product. I can draw a voi on the 2d slices. However, when I try to do the same with the 3d render, I just rotate the brain around. Any tips?

MRIcroGL does not show the drawing on the rendering. This makes the drawing tools work fluidly. Once you have created a drawing, you can load it as an overlay to view it on the rendering.

Alternatively, you could try the drawing tools in NiiVue, which does show drawings on the renderings:
