Multisubtex

[fixeighted]

Is there any way you can make me happy and tell me you can implement this very soon?

I have a 30,000 person crowd and I need a quick way to assign random colours. The meshes are each one colour
and the only ways I can currently use are either multi-sub or the OSL version, both of which have limitations.
The multi-sub I believe has a limit of 32 colours for Vantage - am I right?
The OSL is really slow to add inputs to, after a certain amount, so that is proving painful.

Vray multisubtex would be ideal for this, or even Railclone colour. Sadly both currently can't be used.

If anyone has a better idea on how to approach this then I'd love to hear

You mean 32 materials, right ? There is no longer such a restriction in the latest updates.

The OSL is really slow to add inputs to, after a certain amount, so that is proving painful.

We are not going to be able to implement OSL support any time soon.

Vray multisubtex would be ideal for this, or even Railclone colour. Sadly both currently can't be used.

Which of the "Get ID from" options in VRayMultiSubTex do you need ? Each one will take additional time to implement.

Thanks for that info. I had misread about OSL in the docs - it's horribly slow anyway.
Without the 32 limit that is one option to fall back on, so great, though still very very cumbersome to work with.

I'm using Railclone and so I 'think' it would be face id....can't see that anything else would work with Railclone. I've asked Itoo anyway and they will confirm that shortly I think.
For me right now...anything that works would be very awesome indeed.
I do have a couple of weeks to sort out this particular part of the project, so nothing that I can't put on hold until a solution is available.

EDIT: Yes they say it is definitely face ID Vlad...if you could sort that out any time soon I'd be indebted

I don't think we will be releasing a new build in the next two weeks, as there are bunch of holidays next week.

Can you attach a simple example scene of this setup, so I don't implement the wrong thing ?

Sorry, I didn't mean to rush anyone or hassle...just thought it may be a quickish nightly hack (indicating my thorough lack of coding knowledge).

It's a stadium...so around 30k people based on 32 unique models, instanced in Railclone.
Each person has a material/mat id, so the idea is I use the multisubtex to drive more randomisation,
allowing me easily hundreds of colours with only this simple setup. This was the choke point with Vantage, as there is currently no simple method
to achieve this, as far as I can think of....I've tried many.
Let me know if that's enough info as there's no simple setup I can post really.

Regarding the time period....my deadline is probably a month to 5 weeks away, so hopefully that may be time enough for something to be done,
though please let me know if definitely not, as I'll need to figure out another method.
I am really set on using Vantage for this entire thing but maybe I can comp in a regular render if all else fails....

Note that the VRayMultiSubTex texture is supported in Vantage version 1.4.0.

Thanks for the update...just about to install.
We managed to do it in a different way this time
but this will of course still come in very useful I know
