First time I have seen "Comp Spray" and what a plugin!
Snag is I have installed the folders as directed but the dialogue box does not appear when clicking the spray icon?
Had a quick look around but there does not appear to be anything about any problems with using it with SU 2013.
Do you have any issues with using it with SU 2013?
Comp spray is the way I want to go just need to be able to use the dialogue box?
Will take a look at the plugin you suggested however the trees are all proxies so they only appear at render. Modifiying the proxy will (as far as I understand it) no drive the form of the tree. The proxy is just a "place holder".
Generating proxies for say three tree types, spraying them with "Comp Spray" would give the result I think.
Failing that will have to run with the low poly versions..given the time available.
@abed Removing the foreground trees would lose the link to the environment, uncover the grass which would need to be "3d" rather than painted...or the shot completely recomposed (time not on my side atm).
Thanks for the comments and will take them onboard and yes the lighting is todays job too...
Taken a look at your site btw.
THanks for viewing and the comments Victor and Abed. Much appreciated.
