Hi!
I tried using this method.
I created a bunch of grass, and with ICE have created instances on the geometry.
With the addon Rendermesh I created the file obj.
Imported the obj file in XSI and after exported to Octane.
The result has been obtained even, if I should bring the rate to 150000 issuer frim Surface, and do not weigh anything in XSI.
so, with the rendermesh obj, we are more than 3 million polygons!
Unthinkable, especially with large works on outdoor ..
I hope that the instances in Octane come soon.
