Crash on start of render

Hi there,
I just downloaded the Octane Render demo on my 2008 MBP. I also installed the CUDA drivers and toolkit. I'm on OS X 10.6.6 with a 2.6ghz C2D processor and an nvidia geforce 8600. All of this seems to checkout with the requirements

Octane will start, I can import an obj scene. Except when I click the node for the object, it promptly crashes.

Any ideas?

Just tested the demo on an old lappie I use for it´s pure stamina, very old.
Crash! so it´s a combo of old hardware/software me think.

The 8600 has 32 Cuda cores. This really isnt powerful enough to run Octane satisfactorily and the UI. I think it also has 256 or 512mb vram which will be fairly restrictive.
The demo also represents something from a while ago and is fairly alpha quality so there are a few bugs and half finished bits.
The 8800 or 9800 with 96,112 or 128 cores would be about the min you would want to try with and even then there will be some disruption between rendering and updating the UI.
I suggest you try other hardware or try it on a friends.
Ideally you want say 240 cores and up for Octane to come alive.
Its best if you use two video cards, 1 for the display - the 8600 would be ok, and the other dedicated to cuda use.

Fair enough. Didn't see the number of CUDA cores mentioned, so I thought it might atleast run.

But oh well. Back to CPU renders I go.

Thanks

Sorry about that

It possibly does run but it will be very slow with 32 cores and the scene navigation and UI refreshes will be disrupted...
The video choices for Apple are a bit limited but you might find a GTX285/1gb - 240 cores - and use that in addition to the 8600, or there are the Quadro 4800/1.5gb - 192 cores - and Quadro 4000/2gb -256 cores. Make sure your power supply can handle them though.

Well I'm on a laptop so no luck with upgrades till I'm out of college and can actually afford a decent system. Haha....ah the student life

hmmm well

thats a bit of a downer in the meantime

I see some laptop 8600 may even be 16 cores...

You need to find someone with a desktop who would do a fine upstanding and hardworking student a favour

Perhaps you could buy an Octane license anyway while they are 'cheap' and run it on someone else's pc as needed?

I had a thought in my mind, student life is not the main problem

It´s the girlies, and the alcohol, but if you´re talented enough ps me, and I may suprise you.

I´m awful with the joke that is not you though, I mean are you a Russian leftover that has internet begging for help?
Post your work on the gallery, I´m sure my pocket will be open for a future if you´re talented.

Just tired of lack of it begging for fairness.

well tis not even the girlies or the alcohol to be honest (Don't drink and girls don't cost a thing). I'm doing a 1yr intensive which literally leaves you no time to work outside of school(and also I'm an international student so technically am not allowed to work either). So this system has to last me for atleast another year, which isn't too bad. Deffinitely not complaining since it's powerful enough to animate on and sculpt on. Rendering being the only issue, which I thought Octane might help with, but nothing lost in trying.

Maybe if I can find a friend with an Nvidia card somewhere, I'll try and post some recent work up here.

Thanks for the advice though:-)

At one time Refractive were considering an upload-to-render service using a couple of Teslas.
Not sure what became of that idea.

I guess some enterprising person could start doing that anyway.

Perhaps you could make a deal with someone here to do some renders on a pay as you go basis rather than worry about hardware and a license yourself.
I gather you have coursework where some renders are required?
