Scripts for Forest Pack

You could use this line of code to select all the object in the scene:
select (for s in geometry where classOf s == Forest_Pro collect s)
Alternatively you could easily select all the Forest Objects using Forest Lister.

Both your answer helped me perfectly well.
Wish/request 2
A way to set "Auto Assign to Active View" on all forest items in the scene. I encountered huge difficulties when I was setting up a test-scene with several samples. It ended up being too many items to be renderable. I had to go through the forest objects one by one and set Auto Assign...
Screenscene vfx:
Hurray!
I was supplied a scene from another post company who'd written an instancer for maya and arnold to do digital set extensions. We'd been given a huge collection of alembic caches, texture files and a single maya file that had point helpers named after the model that should have been scattered on it. I was able to split the objects into layers based on their names and then bastardize your script to create a forest object with a tree matching the position, rotation and scale of each of the point helpers.
Now rather than 33,000+ vray proxies in my scene, I've a forest object for each of the 90 types of objects scattered in the scene and something way more manageable to deal with.
Much appreciated Paul!

Instance lights on Forest Pack items
This script instances any object to match the position and rotation of items scattered with Forest Pack. It can be useful for distributing lights, splines, particle systems or any other non-geometric object that it not able to be scattered directly with Forest Pack
To use this script:
- NOTE: To return correct transform information, Forest Pack object must be scattering custom geometry, not using one of the built in billboard templates.
- Press the "Pick Object to instance" button and choose the object you'd like to instance, for example a light
- Make sure a Forest Object is selected.
- Click "Instances to Forest"
The new instances are created with a combination of the source object and the Forest object's names. To delete these.
- Make sure the source object is chosen using the "Pick Object to instance" button
- Select the FP object
- Click delete instanced objects.
Note: Because the delete function is using the names of the FP object and the source object you should not change their names if you would like to use the delete function.
Here's a video of it working
I hope it's useful for someone.
Many thanks!
Paul.

Hi Itoo
Can you add a little script to "randomize seed" a selection of multiple Forest Pack object in a click, it should be really interesting for scene that we re-use...
Cheers!

I've done a little thing like that :
$.seed = random 1 999999
But it's really limited, because the result is apply in the same time on each forest object...
Damned...
It work, for sure... But i'm pretty sure it could be better...
