Author Topic: Exposed parameters not being affected by blueprint  (Read 1040 times)

Hello all;

I've created a substance with 3 exposed parameters.

Editing these parameters has a visible effect on the outputs in substance designer, in substance player, and in 'Unreal' if I edit the substance graph instance directly.



However, what I'm trying to do is control the parameters using a blueprint.   

A substance with exactly the same named parameters DOES work in blueprint, and I've copy/pasted the nodes to ensure I didn't make a typo - several times, since I was sure that was going to be the problem.

I still can't get it to work, though.  The sbsar is here:

Any chance someone could try it in blueprint, and see what I did wrong?

Tested in Unreal 4.18.2, Substance Designer 2017.2.3, Latest substance plugin.

Any assistance appreciated!

Hey Alex Jenyon,

Can you post a picture of how you're setting up your blueprint graph?

Hello Keston;

Thanks for the reply.

My blueprint is almost identical to the one in the allegorithmic documentation:



It also works with a substance that has identical exposed parameters. 

Many thanks for your help!  I can send through the unreal assets or the mesh if needed.
