Buffering issues while trying to create a physarum simulation

Hi everyone,

I am having trouble getting a physarum simulation in Max up and running. This is my first attempt to go into jitter and I have managed to get the fundamentals of the sim up and running but:
No I want to integrate it in a interactive context and it seems to be the case that the buffer of the four pix objects that i have feeding each other are actually different than the four textures that they write to. But if I specify their output texture with the @out_texture attribute the objects break and cannot be recovered.

What I would like to happen e.g. is: The world is running => I send new noise to the textures => It resets the sim.

But: On loading the patch takes it's texture dimensions from the initalizing noise, but as soon as the world is rendering nothing that gets sent to the textures (noises or blacks) will reach the feedback circuit.

Can anyone help me with this?

Best Regards
Benno
