also posted in the itoosoft forum.. just to keep up the pressure 
grmpf…
I’d love to reply to the topic but I don’t seem to be able to write any posts in this forum (as far as i can remember those guys were unlocking my account ages ago…)
reply from Itoosoft:
I’m sorry but technically it’s not possible. Forest uses two methods to support the render engines:
a) If the engine provides a SDK, we write the implementation (VRay, Mental Ray and Maxwell Render).
b) In other cases (VRay-RT, Arion Render, Octane, Thea Render and Corona Render), we provide an interface to their developers, so they can read the Forest items and instanciate them (simple scattering).Forest Color requires to write a custom material shader, so it’s supported only if the SDK is available and it allows this type of shaders (currently VRay and Mental Ray).
I have an SDK now. But even without it it was possible to do with single simple existing method for multiscatter.
Great, so what do we need to do to make this happen
Carlos Quintero seems to be the guy to contact carlosqg@itoosoft.com
or should I just reply on the forum and say there is now a SDK and they should contact you?
ok, I’ll contact the guy
fantastic!
Peter, it’s nice to have you on board. Did you see my post at the bottom of page 4? I know it’s not a complete solution but it’s a way to make some of the color variation possible already.
I did thanks. Maybe I should suggest that I use the multiscattertexture on the itoosoft forum as a way of spurring them into action 
That’s certainly one approach 
hie whenever i try it use forest pack with corona as soon as i hit render it crashes
i tried it with mental ray and it worked but not with corona
i am using alpha 5
Make sure you have the latest multiscatter version, some older ones were causing crashes.
i got it working now 
yayyy
with the latest lite version i made a jungle scene too
HO HO HO
Could you possibly explain your grass material? looks great while not being too translucent.
thanks
is there a reason multi-scatter and forest pack require so much ram to render something over 30mill polys, i struggle to keep it under my 24gb limit unless i reduce the amount being scattered, dont have this issue when trying with vray
I am having crash on max 2011 with forest pack pro.. I am using latest corona. Am I doing something wrong? Sorry I am a first time user of corona..
What forest pack versions are supported by corona?
The reason is V-Ray has render-time geometry, but Corona doesn’t. The second reason is Corona rendering whole scene at once and have to store all the assets in memory when V-Ray’s buckets uploads and unloads assetsts by-demand.
That looks class man. Brilliant!
How i can use forestpack color? I found this topic on itoo forum http://forum.itoosoft.com/ upped some freebies 3D chairs but i can`t see any changes when i am following tutorial Forest Pack Beginner Course: Tree-Lined Canal Forest Pack Beginner Course: Tree-Lined Canal - Part 3
Who can help me and write steps of right using color tint in corona?
