Hedges using Pflow

V-Ray V-Ray Common Tutorials, Tips & Tricks
1

After searching the forums for a while (with no luck), I am resorting to asking the users if they know where a thread is, Recently I saw a thread that showed a technique where the user had a displaced box for the base of the hedge and a few scattered leaves over the top for a very realistic result. I think the example he showed were using text for the shape of the hedge. I found this one from TGraphics http://www.chaosgroup.com/forums/vbulletin/showthread.php?t=32306&highlight=bush,
but the one I’m thinking of was more recent and looked better (sorry Tgraphics).

I thought the thread was started before July 7th so the recent forum crash shouldn’t have affected it.

Thanks,

Never mind, I just checked and it looks like it was posted in mid July so its toast.

Hi Bret - I posted the thread about the topiary hedge with particle flow and displacement. I will try and dig out the files and repost when i get the chance. Did you have any particle question?

Yes, please re-post. Cheers.

Here is a tutorial about the process:

Thanks, I use Parray for hedges quite often. However I would like to see the tutorial for doing hedges with Pflow.

That would be great, thanks!

+1 Those hedges were amazing.

I have automated this thing a bit.. you may have to change the code a bit: - Changing the numbers of leafs
- Changing size (height / length)
- changing the diffuse map and opacity map

run the script, and select multiple objects and end with clicking the RMB.

huh? How do I use this code?
When I copy and paste it in a new script then run it, all I get is array undefined

Chris, any chance you can repost your work that was lost with that forum crash?
