PRman is too rich for my blood. I'm still using BMRT, though I keep meaning to explore switching to aqsis.

There is one called Angel that isn't too shabby either.

foetz.. do you use Standalone Mental Ray somehow?.. i'd like to set up my Origin as a little renderfam using Mental Ray .. since my main app I use for my job is Softimage|XSI ... it would be nice to use the Origin as Rendering backup machines ..

i'd like to talk with you a bit more if you're into this.

cheers.

Mental Ray

Unread postby Timberoz » Tue Feb 15, 2005 10:51 am

This is properly a silly question, But here goes.......

Is anyone using Mental Ray on IRIX to render 3DS (Max) files? I sent an email off to mental images GmbH asking if this is possible, But the just replied that my question would be answered via a reseller. I am wondering how successful this would be to render HD images on a origin 2000? Would there be any advantages using this method over a standard windows render farm using sgi 1100's.

Does anyone know the costs involved for Mental Ray for IRIX? is it a per CPU license if not supplied with a package like Maya?

Speaking of RenderMan, I just received the following today:

Hi Everyone,

Due the growing popularity of 3Delight, as well as an increasing
demand for commercial use, we will be releasing the next version under
a new license agreement by March 1st. Under the terms of this
agreement, 3Delight will continue to be free for any application
(commercial or non-commercial) for up to one license.

We feel this new policy will:

- Enable non-commercial users, as well as those working on small
commercial projects, continued access to 3Delight free of charge.
This is our way of promoting a wider adoption of the RenderMan
standard.

- Provide peace of mind to those users working on medium to larger
commercial projects as the software will no longer be limited in
time.

- Ensure the continued development of 3Delight by sharing its
development costs with those using 3Delight on medium to large
scale commercial projects.

The cost per license (after the free one) will be 1000$ US. The cost
for one year of support (e-mails and regular updates) will be 150$. If
only the free license is aquired, the cost of the support is 250$.

In order to implement this new policy, a license key will be required
to use the product (even for the free license). All licenses are
floating which means they can be used for any computer on a network. A
single license will let you run two 3Delight processes on a given
machine.

Thank you for your continued support,

The 3Delight team

----------------------------------------------------------------------

You received this email because you downloaded a version of 3Delight
and requested information at this address.


What was the last 3Delight version for IRIX anyway? I seem to only have 1.0.6 here and it's no longer available on their download page at all.

as long as you're restricting yourself to only using standard mental ray materials or writing your own shaders and compiling them on the origin as well, it might work.
however you should never ever try to mix frames rendered on different architectures within the same sequence.

(pixar) renderman is more robust than mental ray though. mr can get one into serious troubles when there's not enough ram on the render node while renderman usually manages to finish the job. also speed vs. quality is an issue with mr.

neko: i recall that 3delight development on irix died end of 2003/beginning of 2004.

@Sum][One

I use a standalone Mental Ray on an Origin with Softimage|3D.

With 3D the setup has been quite easy, since 3D supports Irix, you just had to install the Mental Ray standalone (an installer option) and put the hostname of the rendernodes into a so called rayhosts file. Mental ray distributes the render job to all nodes in the rayhosts file automatically.
You can also save the rendering information to a .mi file and start the comandline renderer yourself, so that Softimage|3D itself doesn't need to run.

For XSI, if the Irix Version of MR isn't included on your CDs, you got to ask your Avid/ Softimage Reseller for MR licenses, but it should work (almost) the same as with 3D.

GI Joe states:

To elaborate a bit more. You should not use different architectures (even AMD vs Intel) to render frames on the same sequence. The reason is that each CPU does its calculations differently than other CPUs and therefore one CPU may render a texture one way while another renders it differently.

You will create artifacts and stutters which baffle you if you attempt to do so.

Question, how in the world would you get 3DS Max to render anything on another architecture when it's Windows-based only?

not at all. you would be using mental ray for that which was multi-platform last time i checked.

HD frames

Unread postby Timberoz » Mon Mar 07, 2005 6:39 pm

That is what I was told, that it was multi platform. I have a NT render farm, But it was suggested to me that the Origin 2000 would have speed advantages due to ram? when rendering HD frames over my current SGI 1100/1200's. This was the main reason for heading down the Irix/Mental Ray path. Besides it would be great to put the Origin to work on something practical..........At the moment it is just looking like a thing of beauty in the corner.

my suggestion would be to keep it at that ;) unless of course you want to dig deeper into mental ray and porting shaders, setting up distributed rendering apps and stuff like that.
