Polygon Selection from Image

Recommended Posts

Hi,

 

Is there a way to make a polygon selection from an image? I have a mountain geo and a mask .png based on slope (from Houdini).

 

I'd like to "split" this selection from the original geometry and use the new selection to scatter clones. "Painting" the selection by hand is too slow.

 

I don't want to use the shade effector because it's too slow (Cinema still calculates the hidden clones).

 

Thanks!

You can use Fields to drive selections since R20. Here is an example:
