I have the following problem:
Material Functions are used and created a lot in my material creation process, because of reuse obvisously.
To make reuse faster I already plug a parameter into the function input as Preview Value inside the Material Function (!) and check “Use Preview Value as Default”. I will call this Parameter “Default Parameter” from here on.
This way I don´t have to nessesarly, when creating a new material using this material functions, plug in some values or parameters for each input. The instance of the new material will handle instead, but still if I want to, I can create some values or parameters in the Material and plug them into the MF inputs to overwrite them. So I get best of both worlds.
To already know which material function input is already parameterized from the start I call those function inputs “AP - …”. AP stands for Already Parameterized (would be nice BTW if Epic would mark MF inputs with default values somehow automatically)
However, now comes the issue…
… when I overwrite the default parameter of the MF in the material using this MF, then I will still see (!) the default parameter of the MF inside the Material Instance. So basically I see them twice and one of them being useless then (the default parameter of the MF).
This is pretty confusing for people using the material functions / materials I create. Can I somehow prevent this behaviour so that the overwritten parameter won´t show up in the material instance since it is completly useless after all.
I am thankful for any help I can get.
