Procedural textures with the Substance Engine seem to update very quickly if you turn off caching, modify one exposed variable at a time, modify it frequently, and even then only after you've attempted to modify it 2 or 3 times.
However, I want basically the opposite. For example, units have a "blood" variable that generates blood differently on them as they take damage, as well as a "battle wear" variable that generates scratches and dents, but doesn't revert when they heal.
So to force a variable not to cache, I have to set it to some dummy value, then back to normal, then call
How can I tell Substance not to cache a variable at runtime, so I can change it once and have the texture regenerate quickly?
