View Full Version : Cycling and Onyx+others

Hi All,

I've been playing around with model cycling to test out a few ideas. Primarily with respect to Onyx Tree , Poser, and Organica. There are certain things that I'd like to do and EIAS is either just not capable of these things or in some cases as with Onyx the function has been discontinued.

With respect to Tree Pro I found that I could export a series of fact files with motion out of Onyx that had wind applied. This can then be imported into EIAS and cycled to provide wind functions in Intel Mac versions of EIAS. The main bottle neck here is that I can't find an automatic way to export sequentially numbered fact files from the tree modeling modules. You must export and hand name them one by one that takes a long time. Does anyone who uses Onyx know of a way to automate this process and if not would it be worth requesting as a stop gap measure to have wind in trees in EIAS until an intel version become feasible?

With respect to other programs like Poser and Organica I am able to export multiple sequential files. The problem is that they are either 3ds or obj files. Here importing them is bottlenecked on the EIAS side where each has to be hand imported unless I'm missing a multi file import feature. I wish EIAS on file imports where you set the model type to other would hold that setting until your imports were done. As it stands now you need to reset to "all file types" for every model you import. Seems that should be easy to alter . Matt, is this something you would consider for the next version of EIAS?

Also would be nice if we could import multiples of these other file formats the way we can currently import fact file sequences in EIAS8 since the vast majority of cycled models that I end up using come from other programs and are not fact files. Anyone have a way to automate any of this that I'm not aware of?

Also, another issue is that often models come in with more than one part. It would be nice if there was a way to import say a tree that has trunk,branches,leaves as multiple separate parts,and be able to set up cycling without having to separate all thos parts for every frame. Is it possible to enable cycling to recognize the separate pieces and parent the groups to a single cycling master object or null. This is more of a feature request than a is this possible question. I know that this is more than can currently be done with the existing EIAS8 package.

Just some issues that I've run into recently that a discussion of seems would be useful.

On OS X, I wonder if some kind of Applescript could help with the repetitive tasks.
Never done any scripts myself, unfortunately :(

Obj2Fac can do batch conversions of files into Fac files.

To separate model groups up for cycling I would just use the 'Find all...' command, so you would only need to do it 4 or 5 times to select all the 'bough', 'leaves', 'twigs' and 'trunk' parts and then group them. So that shouldn't take long.

As for scripting, it's not something that Onyx supports, and since they don't support the Mac platform anymore, I don't see them adding it.

You can batch export .obj files from Maya if you have that, Paint effects trees (although nowhere near as good as Onyx) can be affected by wind (and can even shed leaves etc.).

Hey Ian,

Onyx still sells their software for Mac with the note that it will not run on an Intel Mac. Seems that it would not be too difficult to add a feature to the existing software that expands the export to include a range of files from the time line.

I didn't know that OtoF did batch processing .I'm running version 2.1 . Is that current? What is the procedure for batch processing?

Don't have Maya. At least not anything more than an old PLE version so it is not an option.

Regrouping was not too difficult but I'd think if it needed to be done over and over many times it could be painful. Say you have 15 or 20 different trees each with its own 3+ second cycle at 30 fps. Sort of like assembly line repetitive work that is often easily done by software automatically. Just thinking it might be a useful feature to further simplify a common task.

Wow. Someone who is still using Organica. I came to EIAS from Impulse's Imagine and have Organica as well. I never did much with it, though it was fun to play with.

Hey Ross,

A friend of mine who used Imagine for many years showed Organica to me back in 199?. I think I may have been the one who asked Zack for the fact export capability. I always thought it was cool and used it a bit on projects over the years. I still have machines dedicated to running Old OS9 and OSX software cause I hate it when something that I have come to rely upon gets discontinued.

Recently I've been doing a lot of medical stuff that constantly has things merging into other surfaces. Metaballs is great at this but the problem I always have is that the meta shape is always a sphere or otherwise limited. This is of course not very useful for most things. Organica is the only software that I'm aware of that can create very complex meta structures that melt seamlessly together. So I've just started testing with Organica again to see what is possible using the cycling. Results are pretty cool so far. I need to get a better handle on Organica's animation functions so that I can export more useful model sequences. So yes. I'm rediscovering Organica. A truly quirky and one of a kind modeler.

Here is a sample of the very rough test:

I never installed it when I switched to my laptop. I just might have to dust off my old disk and start experimenting with it again. I didn't realize it had a fact export. When I was originally playing around with it, I was only using Imagine for Windows 2.0.

Incidently, you can now download Organica (as well as Imagine 2.0) at

www.imagine3d.org (http://www.imagine3d.org)

It is a user-based website. They worked with the Halvorsons after Impulse fell apart to be able to host the software.

I remember griping about the $100.00 upgrade cost going from one version of Imagine to the next. I guess I should have been more grateful.:cry:

Well I reinstalled it. Unfortunately, it doesn't actually support the fact format. It can output Imagine, DXF, Lightwave, and 3DS files. Other than Imagine, those can all import into EIAS, so the news isn't all bad. It is a fun little program to play with.

BTW, this is a windows program. It does run under Vista without any problems (so far).

Hey Ross,

I have the Mac version of Organica. That may be why I have the fact export. At that time EIAS may have only been a Mac Program. It bwas a while ago so I don't remember clearly. My Mac version of Organica is an OS 9 version. As far as I know they never made an OSX version. Interesting that they have all that software for free on a web site now.
