I have a Substance with an exposed Float called "Skin_Tone".
On my camera I have a 'GUI Horizontal Slider' with a 'Float Variable' called "Skin_Tone".
I have both the 'Set Procedural Float' and 'Rebuild Textures' assigned as well, 'Every Frame' checked on both, both are referencing the Substance Material, and the 'Float Property' for the procedural is also set to "Skin_Tone'.
I'm trying to sync the slider to change the Float parameter in the Substance. Is there something I'm missing?
Thanks!
