Thanks for your answer.

I just want to experiment with it rather than create plausible VFX creatures.

But a simplified version of my question would be;

1) Can you make processes conditional (say a particle reaches point A then it writes a BGEO). I assume it can do that…
2) Could you create feedback loops in Tops, so if the particle reaches point A could those initial parameters be used as the basis for the next generation?

I think I just need to start poking around in Tops really.
Also, I absolutely love that Karl Sims work. I think I saw it on this mini-documentary: []

Could I use the PDG to set up some simple artificial life simulations?
So I create some ‘creatures’ with randomised parameters which have to achieve a goal, say get across a line.
Then if they achieve this goal they can be used as a template for another generation of creatures. And then keep iterating.

I suspect this is way beyond my technical level but could be an interesting design approach perhaps.

Tutorial on Look-at constraints March 14, 2019, 6:14 a.m.

If you go into your cameras parameter interface and then toggle the ‘show invisible parameters’ you'll see the ‘look at’ controls. Tick them to make them visible. Then you can drop in your target object. This all works at object rather than SOP level.

To be honest I find cameras pretty unwieldy in Houdini although this could just be my inexperience.
