Modo texture replicator support

[senolite]

Hi,

Is there any way I can use the Modo texture replicator feature with Octane?
I am currently on the latest version of the Octane 3 series.

I am trying to use a particle simulation where the simulation is used in the texture replicator to have a texture in place of every particle throughout an animation.
In Modo native renderer that works perfectly but in Octane, I only see the texture on the plane itself, nothing happening.
If there is an Octane workaround, even if it is using the native renderer, I would be happy with that.

Thanks for any help, currently it forces me to go back to Modo's renderer for this project which was not really why I bought the license.

Hi. From your description, I don't think this would be possible to do using an Octane Material. Instead perhaps you could have the particle generator control to position of a bunch of planes, which have the texture applied to them.

Would it be possible to create a osl Texture which uses point data to project images?

[senolite]

I think both solutions sound viable however I have a lack of knowledge on OSL.
Created the solution Paul mentioned at it actually provides more flexibility as it allows for a material to be used instead of an image. Thanks for thinking with me!!

Are there any news about this or new ideas how to implement this functions?

I'm guessing you can probably do something like this with OSL, but its a bit too advanced for me.

You can search for "texture bombing" or "chaos mosaic" to see if anyone has written something like this already.

I found a couple of links that may be a good start:

Actually I just found this on the OTOY forum too. I havent tried it:

Thanks funk! That is indeed pretty close. I can't achieve a completly seamless Texture but almost. Also it doesnt work as an imageink. With the texture replicator it it possible to use a particle source to paint textures on a surface. Is it possible to get this particle data into octane osl?

Ok i spent the whole day to figure this out and i think i'm on the right track

I thought about this too. I don't think it's possible, but the OSL docs have details on accessing instance IDs (See "hit:instance-id" at https://docs.otoy.com/osl/extras/ ).

So there may be some creative way to use the particles via a replicator (which converts to instance IDs in an Octane scatter node).

This is all way beyond my skill level though
