I have selected a node on my subgraph and would like to expose the perameter "seed", but the option to expose the perameter is not visible. This appears to be true for every input other than this one as well. What can I do to expose the perameter?
The Random Seed is usually set to inherit from the parent or input and will appear in the material parameters when used in Substance Painter without exposing it.
However if you want to control a particular node separately, add an input parameter to the graph - I've made the identifier in mine 'node_random_seed'.
Then in your node you can set the random seed to use existing graph input node_random_seed. It will though still be subject to changes in both the material graph random seed and the individual random seed, but is of use in ensuring that say different instances of the same node use different random seeds.
