hey thanks guys,
the problem was that I basically didn't understand it the right way. Now
all the clouds have cleared up and I was able to write the node.
Cheers
Vladimir

Hi list,
I'm having little trouble here with a custom ICE node. I didn't touch
the subject for a long time so I'm a bit confused :)
What I want basically is a node with an input which takes any context,
loop over all the items from the input and output a single value. Is that
even possible? I've found the BBoxGenerator example and that's basically
what I want but I couldn't get my node to load in Softimage as soon as I
have a different output Context type than what I have as input context
type.
Hi Vladimir,
The only other things I can think of checking are maybe the context
constraints when you define the ports i.e. make sure they're not using the
same constraint map and, possibly, ensuring the node definition is set to
single threaded (like BBoxGenerator). Using single threaded gives you much
more latitude in mixing ports of different contexts whereas multithreading,
by default, seems to enforce stricter rules about input/output port
evaluation...often resulting in mixed input/output ports being evaluated
incorrectly. In fact, almost all the time I find that multithreading
requires that input and output ports be in the same context.
I tend to use multiphase a lot of the time since it seems to bypass lots
of port context issues (probably because all the initial phases are single
threaded anyway).
