I would never use proxies for grass... I use simple planes with a nice mxm found at
http://resources.maxwellrender.com/sear ... v2=0&tipo=

From forestpack I choose that my planes will always look to the active camera.
Play also with a small size transformation.

Here are some old WIPs for customers.

Ah cool. I havn't considered using a simple material with displacement. I guess it will be best. The aerial shot will be around 20-30m camera height.
I bought Forest Plugin now and it works so far in my tests with instances. Already lost too many hours with this issue and have to move on.

Thanks a lot for your help and your time!

No, no displacement!!!
Simple plane for forest object, 35X20cm, and the material I show you... Simple clipmaps but with small scale transformation it looks great.
