consider mirai (nichimen/izware). ;) a very neat plaything. look it up on youtube if you don't know it yet.

skipping maya might be a good idea. there're tons of maya tutorials everywhere and the irix version is no different either. also maya didn't change much over the years.

I have two Maya tuts planned. Primarily an orientation tutorial for 6.5. Though the basics of Maya haven't changed there is much that is quite different in overall setup between Irix and other Maya.

Maya is my primary application at work and has been for over a decade.

One thing I often find with even basic Maya tutorials is that no one really explains the general overall intended workflow idealism behind Maya.
I have shown things to people that had been using it for 5-10 years that they had no idea about and are integral in overall understanding how to approach ideas for getting the most optimal workflow out of Maya. I've watched Gnomon tutorials and have shaken my head knowing full well an "instructor" had been completely oblivious about basic core Maya concepts.

But, worry not. There isn't going to be a long library of Maya tuts. Mainly two different videos.

One for overall Maya basics mixed in with Maya design UI and scene data philosophy.
One for showing the changes between Maya 1 through 6.5 to show how the menus and items changed and how to quickly set them up for
use in a modern fashion.

Many of the current marking menus, particularly the selection sensitive context marking menus did not exist until Maya 2008.
You can still use the basic MEL commands and Marking menu setup to create very similar behavior in Irix maya as well.

BUT... like I said, there will be far more other 3d Apps tuts.

I know Softimage is popular for SGI owners.

I will also do a Mirai tutorial as I have been getting used to it.
It was familiar somewhat because I did use Wings for a about a year before Modo 201 was released.

Lightwave will get some love. Same with Houdini. Man, Houdini is very rough compared to the current version but still very capable.

I am up to speed on Alias though, the renderer included is very limited vs Maya or Softimage's even basic software renderers.

I am on the fence about Blender. It is very capable now days but I've never cared for the UI much. Maya, Softimage, Zbrush, Modo all allow for so much customization in both hotkeys, quickmenus, UI layout, etc that it is very hard for me to deal with 3dsMax, Cinema4d, or Blender where you really just have to learn their layouts and deal with screen space issues.

And I am always open for suggestions for anything I don't know about.

alias' raycaster/tracer is much better than the default maya renderer ever has been. it looks better, has full smp support and is also faster.
in fact that was one of the main reasons why i stuck to alias until maya had mental ray.

Are you talking about Alias Power Animator? I am looking at plain Alias and the renderer included doesn't seem to have those options. Maybe the one I have installed isn't with the Raytracer?

the renderer is always the same but depending on the license you have more or less options. late alias versions have 5 renderers in total:
- raycaster
- raytracer
- powercaster
- powertracer

the ones with "power" are just the smp versions. the 5th is sort of a plotter for line drawing style results. there're also additional render features that have to be licensed such as atmospheric effects.

good to hear about mirai! this is probably the last remaining platform where you can still run it as intended. (on windows, the renderer stopped working with XP if memory serves).

about blender: i think i mentioned this before but it's insanely customizable. technically no need to learn the defaults - but changing it all requires effort. look up blenderartists.org and search for maya/silo-esque input setup to have a look. you can add pie menus, right-click context, maya-style hotbox, reorganize the interface and so on.
anyway, i don't think the state of blender on irix is up there to support much of that. :)

Yeah, modern Blender is very good. Though I never have sat down to use it since around 2005-2007. I was using it's fluid solver as it had a better particle mesher than Realflow for a couple years. Then realflow improved. But, looking at videos today it looks like Blender is as capable as any apps in a generalist sense. The sculpting looks pretty nice and the simulations look pretty good too.

I will probably do a Blender install and see how it is on Irix at some point.

I think I have Mirai on one of my o2s but haven't dove in. Hmm, time to fire it up and look at it.

Will you be doing any more tutorials on Softimage? Is it possible to offload the render process in SI from the O2 to another SGI machine, like a dual Octane or Origin?

I am so wanting to do more tutorials.

I am finally going to break down and get a PVO card for the Octane as the documentation says I can capture desktop video.

There are two on Ebay for $400 and I will be picking one up within a week or two and finally diving into the tutorials I've been wanting to do since Nov.

I have looked into rendering across multiple SGI.

The only situation I know where you can use "satellite" rendering is with Maya 6.5 and Mental Ray. Though, I am not sure how much this was used.

Satellite Rendering is using multiple cpus across multiple computers/servers to render one frame. So you get more square buckets cooking your render from multiple computers. Each bucket (render square) is a CPU.

Network rendering is just having an instance of Mental Ray running in standalone mode on each workstation and when the network rendering mode is utilized it will send individual whole frames to each computer available. Then the computer will utilize its own resources to finish the frame and then save it to a network mapped drive.

I am not sure Mental Ray in Softimage has the ability to do satellite rendering.

We use Satellite rendering with vray quite often in the vfx industry. Usually if there are a couple computers in the farm going idle it will grab a few for satellite rendering. Then instead of 24 or 32 little 16x16 buckets I end up with around 64-96 little buckets and a 5 minute render, which used to be a very very fast render time back in 90s/2000s, can now be reduced to 45 seconds.

I had a great interest in seeing how much leverage I could get from a similar process in SGI machines since they seem built for this exact situation architecture wise. 64 Bit, big data pipes, etc.

But, it seems mostly that it is fairly straight forward local CPU based and then you use network computers to run individual frames one at a time on each computer.

Maya 6.5/Mental Ray might be the only satellite render method and from what I have read it didn't seem like I could find one usage case of it with/on SGI.

I do remember testing Maya 7 and trying to get Satellite rendering on my two computers back in 2005 and the second computer did render and add a bucket but it would render without textures. So I got this mosaic render where local buckets were textured and net buckets were untextured.

At some point though I will make an honest attempt to figure out what is possible in each 3d application and render engine. Which, if you just need your other computer to render full frames it is a pretty standard render farm situation to have networked computers process one frame at a time.

As a matter of fact i know Lightwave 5.6 can do it on anything. Setting up screamernet is not too hard. Mental Ray or Softimage software might be a little more tricky. But usually it involves installing a render node or copying the render software over and having it run on the network computer waiting for a command from the render hub. Since I bought the o200 specifically to do this task I am hoping that if/when I figure it out that I can make a tutorial that makes sense. :)

it has, with mental ray 1.x as well as 2.x :-)

Just subscribed to your youtube channel.
I've just installed Softimage inside my O2 box and it has been a little shock to watch that screen after 20 or more years......inside an Sgi machine!
My only experience with SI|3d was me trying to play around with Windows NT machines mounting an old wildcat card taken from an Intergraph workstation (TD something, double Pentium Pro), my favourite 3d app was 3d studio max at the time.
I've just bought the "Inside sofimage" book and it is on its way from UK, your tutorials will be the natural companion in my vintage-3d knowledge path!

Trank you for this tutorial. I followed it through on YouTube, but I get a black rendering output with mentalray.
Can you upload the final scene here ?

Thanks for the compliments.

I have recorded another Softimage tutorial today just using my phone again.

It is based around display settings, selection modes, and some basic modeling functions.

I am putting it in Premier now and will upload it later today/tonight. 8-) :mrgreen:

EDIT---

Still uploading... 64% this morning. I think I have the slowest upload in Marina Del Rey. :/
