Onyx tree question
show user profile  roccodiablo
Hi all

I've heard a few people mention onyxtree recently and I'm thinking about purchasing it.
In the attached photo - will onyx tree be able to do all the foliage or will I need to look elsewhere?

I'm modeling this building and will animate it so need the foliage to be fairly low on the old polycount.

Any advice would be appreciated.

nice building.. onyx will pretty much do all that foliage, as for the polycount ts has some display settings to display the canopy in full/mid/low res that can help you play around with plenty foli..

yes, onyx will reward the user who gains more and more experience with it. you can certainly control every aspect of the foliage creation including poly count. you'd probably be better off using alpha-mapped planes for the leaves instead of individually modelled leaves. there's also use galleries of trees available.

but, as mentioned, to get the best from the software you need practise and practice.

onyx tree is awesome. You certainly won't regret buying it. The UI is out of the ark, but everything seems to function just fine. It won't really make lo res trees, but you can make cards etc. To make the tree to the right of the building you'll be looking at about 1.5mill polys to get it exactly the same.

Thanks guys. When anyone mentions foliage - onyx usually gets mentioned so I assumed it'd be a worthy buy. I was just curious if it'd do the bushes by the water etc - sounds like it should.

The reason I set myself this to do was that I've not really used foliage other than an odd plant here and there. Am I right in thinking the foreground foliage should be models and the background be alpha mapped planes?

Any pointers on how you'd tackle this would be useful. I've modeled the building and water - if I get the foliage right I reckon it might look pretty good.

I've found a good way to do nicely lit trees that render fast.

Set up your trees in onyxtree and then use the vertexpaint tool in max to bake radiosity skylight into the vertex map. Then use the vertex map with the baked in lighting as an ambient light. Use your sun and raytraced shadows with some translucency on the leaves. You can get VERY realistic looking trees with no flickering during animation. They render super fast as well.

If you instance trees and rotate and scale them a little you can fit a lot more polys into your mem. The only poly count that matters is the original count before you instance them. Any instances are effectively "free" I've easily rendered over 200 million poly tree scenes without difficulty because I only had 10million or so polys in my original trees.

Hope this made sense.

*climbs out from underneath a pile of words*

Hmmm, I've heard of all those words before but not in that order. I've heard of people baking light solutions etc but my searches never came back successful. I think I get the concept - that it saves the renderer making the calculations as the info has been baked, but it's the baking bit I'm lost on. I'm really keen to understand what you're talking about though as the end result ""VERY realistic looking trees with no flickering during animation. They render super fast as well."" Sounds perfect.

Maybe I should google some of those key words and find some tuts as I'm not really sure where to start with questions on this!

I guess finding out about vertex paint would be the best place to start?
Thanks for your help.

just get it and play and find out. Dub has a valid solution, but not the only solution. there are numerous ways to optimise and render.

yeah, good plan. It's Friday, the sun's shining and I'm excited about going home and playing with some foliage.
I'll post up some results
Thanks again

Strat makes a good point, there are a million ways to do things, play about and you'll come up with something that works for you and your pipeline.

good luck, make sure you post your work..

I personally convert the onyx trees to editable polys once I'm happy with them, and then convert them to Vray proxies and instance them all over, it works just fine for me..

I purchased ot a few years ago. So:


-solid company, won't dissapear soon
-fast assistance, friendly interactivity, they send me the act. codes on saturday because I was in a hurry.
-Great product, great trees.
-Their nursery rocks.


-I had to render myself a comprehensive species visual index
-Flowers still out of treestorm -their inside max plug in-
-Some bucks needed everytime max upgrades
-Funky default vertex colours texturing

All said, I don't regret a bit the investment. Go for it.

Dub: Sounds interesting...

manalo, that's interesting you say about activation codes on a saturday. I sent back the registration file but didn't get the codes. I assumed I wouldn't get them now until monday. Perhaps a call is worth a try.

I'm trying to get this done by friday so I'll post up my efforts.

Indeed the call was worth a try. The codes are on the way!

just thought I'd post an update after purchasing onyxtree.

Looks like a lot to learn! I had a look for the take-a-look-at-my-photo-and-make-a-tree-exactly-the-same button - but sadly it was nowhere to be found.

Now the foliage is in it makes the building texture look pretty crap so will have another go at that.

makes a big difference!
Don't fall into the trap of making the leaves too big.

Nice work so far.
