BA_illum_bruteforSSS for Arnold crashes Softimage

[andy58]

Can anybody comfirm the BA_illum_bruteforSSS working with SITOA 2.6 or Arnold 4.0.x ?
I've done a fresh install of Soft2012, with a clean Workgroup for SITOA 2.6 and the latest BA shaders 25.01.07.

I'm getting hard crashes of Softimage.

On another note, is there a way to get the hands on the sourcecode for some green?

Thank you,

Andy

Anybody? Buller?

I will do some tests once I finished the new fluid shader version.
In about a week.

Thank you Holger,

would you consider sharing the code for money? We've built an asset that relies upon that shader. But compatibility wise we're back in SITOA 2.1.1 land.

Please consider & thanks

Hi Holger,

I understand you're busy with the volume stuff, but could you take a break and give me some feedback?

Many thanks,

Andy

Hi

Yes, the volume shader should have been finished last week.
I decided not to implement all features and get a version out today or monday.
Then I can try to fix the raylength sahder.

Hi

I tried, but was not able to create a workaround for the Arnold crash.
The back lighting crashes the shader.
I will check if the Arnold guys have a workaround to the crash.

Thank you for looking into this.

Have you put any thoughts on shader source code buyout?

Have a great weekend.

Hi

The shader is part of a larger compilation pipeline, so it cannot be easily removed.
The shader alone required about 40 source files to compile.
And the pipeline generates source files before compilation.
And a new developer will take some time to dig into my shader source.
For me it would be way faster, but as you know I do not have much time. I am searching for developers taking smaller parts from my task list, but did not had much luck finding good dev people.


I have some more information how to create a workaround.
It will be slower, but it will work in Arnold 4.x.
The volume shaders are released in about an hour, so I have more time for the essential shaders.

The new version will be available in about an hour on my website.

Ok, I got some workaround information for the crash from Solidangle.
With a little bit hacking it is possible to speed the shader up again.
But it could break again in a future version of Arnold.

Thank you Holger for fixing this.

We're still interested in having the shader inhouse. We do understand the effort of ripping it out of your pipeline. Depending on how much you're willing to have us have a look at it we wouldn't mind helping in doing the hard work I'll see what management has to offer in terms of compensation for the shader. Or if you have a price in mind, please PM me (german is fine).

Thanks again,

Andy

I will check if I can collect all function definitions and shader replacements into one source file.
Right now the version is build for later Arnold versions. (but therefore slower at the moment)
