Welcome to thisTouchDesigner tutorial on Multiple Objects Instancing! 🎨✨
In this video, we explore the fascinating possibilities of instancing through the Copy SOP and other powerful tools in TouchDesigner.
This is part 1 of a 2 part serie.
In this first tutorial we will build the backbone of our network.

Very interesting way of doing things... I had no idea! I always used Geo comps for instancing.

I would say that it is the best approach 99% of the time. But when you need a more custom approach on attributes, the copy Sop can come to the rescue ! Cheers

The example can only record the instantaneous state of the model, which is obviously not enough, if the action of the model can be retained. Thank you for sharing, I will continue to follow you and look forward to your follow-up

Yes you’re right! This will only export the immediate state of your setup, but in some case that’s what is needed, which is never possible with the Geo Comp. Cheers

Not sure I understand correctly your question

@@smoothisfast_design How 3D models are interpolated in the rendering of model animations so that they don't have the same action. I know that planar maps can be interpolated with tex3d. But I don't know how to set up the model animation. Hope it can be answered,

I am going to say the same that I already told bileam: This is not Instancing. This is maybe instanciating but call it what it is, copying. (Geometry) Instancing is a very specific approach to rendering geometry where you only send the geometrydata once to the GPU, coupled with a fixed set of directions of how to draw them. This is inncredibly fast and the main reason to use it. When you copy the SOP-Data using the cpySop and send it then to the GPU. All transformations are handled by the CPU, blocking frametime, you are lso blocking additional time by sending a lot of repetitive data to the GPU (which takes a lot of ime.) /rantover.

No arguments here; you’re absolutely right about the distinction. I did mention that this technique isn't the optimal real-time approach. However, I believe that there are scenarios where the precision and control offered by CPU-based processing can outweigh the speed advantages of GPU instancing.
