Does it make sense to use 2 of the same procedural noise (or whatev) in one substance?

like the title said. Does it make the proccess slower?

You would have to pay for it twice. 

Performance issues tend to come from huge serial nodes like multi material blend rather than the noises though

Once cooked to sbsar, these occurences are optimized and the noise will only be generated once.

so for organization is it okay?

poopipe

Basically yes.. 

Jerc..

Does this instancing apply to all nodes and does it still work with nested graphs?
