Randomize substance instances with Blueprint

Development Rendering

Hi,

I created a substance and imported it with the Substance Designer plugin. Now I want to set the random seed input of the substance for each instance of a mesh through Blueprinting. So that when I have a rusted barrel substance, each barrel can have a random seed so the rust would show up on different spots on each barrel.

I tried it in a Blueprint construction script, here’s what I have:

But that is not working. Any idea on how to get this working?

I am not great at this, but how come you are getting random int with a of 0, so it will pull 0 everytime?

Thanks for that But even when changing to 1000 it still doesn’t work.

You have add either an Async rendering node or a Sync Rendering node at the end of your chain there so that the changes updates…

Did you manage to solve this ? As I’m having a similar issue.
