Hello,
Is there any way to access the information about the current iteration number in a node (any node?) that is located between Block Begin and Block End? I need to change the parameters of nodes depending on the current iteration step.

hey, I made a similar post yesterday [www.sidefx.com]. To keep track on the iteration, you could keep incrementing a constant value in a mono channel like in the slapcomp block (depth).

But I'm as well still looking for a way to either read that out in a parameter to eg. drive a switch sop in there. Could even be something hacky (idk...like sample pixel 0 from the buffer w. python), or ideally make use of layer attributes for that. Haven't found a way to get a layerattribute read out in a parameter (or write back to it) either, unfortunately.

Thank you for your reply.

I tried to find some solution, but I didn't.

I decided to solve my problem from the other side and move everything to OpenCL node (in my situation, this is possible). It allows you to set the number of iterations, and the current iteration step is available through the @Iteration variable.
