Placing objects via terrain mask

[saindd]

I've been working with World Machine for a while and i'm producing some quite useful masks for my terrains: grass, bush and tree masks, as well rock masks. Those masks are really useful because not only they are precise, they speed up the workflow.

Is it possible to import a mask into the Forest tool or the object placement tool and place whatever object i configure to be randomly placed following the mask data (blacker = less items)? If not, how would you guys approach this? With a shader? Right now, i'm using the mask as a diffuse terrain texture and manually placing stuff. Which is AWFUL.

Not at the moment - but there is a precedent set in the GroundCover object - it can mask its type by the terrain material layer, so in theory you could use the terrain layer number as a criteria for placement. It's a starting point....
