[little bug+question] render size+Indigo 4 linux

[Pibuz]

Hi all! I've recently encountered some limitations launching a rendering, so i decided to post a question here.
My problem is render size: i try to render a scene at 1750x1200 and it all goes ok. But if i try to render the same scene even 1800x(xxxx) indigo crashes for a C++ problem, even if i don't exceed my available RAM. The fact is that a very simple scene DOES render at the same size and more (even 2552x xxxx), so i don't know what it is...You guys have an idea?
(I use Indigo+SkIndigo)

Second thing is the request: does indigo for linux support a Linux Live CD? I mean: could i launch linux from a cd, then read my exported igs from a folder in a memory stick with an indigo put in the same memory stick? Just to know if

Hey Pibuz...

The issue you described is related to RAM usage...
As long as you use 32bit Indigo, the app will crash before reaching 2GB of RAM usage!!

You can somehow patch Indigo to be LAA able and use 2GB RAM without crashing on 32bit...
I can't remember who told me how-to-do this :/

Hi zomb! Listen, my problem is gone deeper..uff..
I tried to render the same scene 1800x xxxx on another quad with 4GB of RAM and it didn't render either.. So my guess is: is this 2GB ram a limitation of the program itself?

[Zom-B]

So my guess is: is this 2GB ram a limitation of the program itself?

In theory optimized Applications can use a max of 2GB in 32bit!
But afaik Indigo isn't this way optimized and crashes beneath this 2GB RAM usage :/

I think BbB was the guy who told once on how to patch Indigo to use LAA and handle 2GB of RAM in 32bit mode!?

try to use console mode, reduce Super Sampling or force Bounding Interval by reducing "bih_tri_threshold" to 1 to save more RAM!

Ok: thank you!
Any tip about the live CD linux 64 bits?

[zsouthboy]

You can render huge, ridiculously huge sizes in Indigo x64
Are you not running a 64-bit OS?

I've done over 10000 x 10000 before...

Hi Zsouth!

You can render huge, ridiculously huge sizes in Indigo x64

GOOD TO KNOW!

My only 64-bits OS is an Ubuntu 64bits Live CD downloaded today! My only question is: can I simply launch my windows-exported igs file with an indigo4linux64bit from a memory stick?

[zsouthboy]

Yes!

You should be able to do so, right from your stick.

Let us know how it turns out - and share the render!

I swear it wasn't me. Would be way above my IQ.

[zsouthboy]

BbB, we all know you're actually Stephen Hawking, rendering via indigo on your voice computer

[Kram1032]

yeah You recently updated to 1TB RAM

Hi again! I'm trying to launch a render with Indigo4linux64bits, but i can't find how...
SO sorry to bother you again...
Can anyone post a screenshot or a simple short tut showing how to launch an indigo render with linux64bits? I have already exported my .igs scene (within Windows OS), so i have my 1.igs and 1-settings.igs files (and the texture folder..

..sorry again guys...

[zsouthboy]

Pibuz:

open a console.

cd to your indigo directory (tab autocompletes while you're typing - so typing indigTAB completes the directory name to the first match)

Type ./indigo_console 1.igs

You may want to pass it to nice to make it lower priority (nice -5 ./indigo_console 1.igs)

[zsouthboy]

Oh, and since you exported in Windows, your texture paths and nk data paths are going to be hosed, more than likely.

Manually go into your IGS and find all the file paths you can see to be relative and use a forward slash (so remove drive and folder from the reference: C:\Indigo\Textures\texture.jpg becomes simply textures/texture.jpg - then put the textures folder directly inside your Indigo directory)

Thanks south! Gonna try tonight! Thanks!
