Hi! Try this dynamic texture In Substance Painter 2018 or other associated programs (sbsar) to generate patterns from built-in alphas or any alpha you plug!
PatternGen has built-in 30 alphas you can switch by a slider, so it's very handy. Then play with just a few but enough parameters to find what you want. No long up-down scrolling, so the process is time-saving and productive.
PatternFromInput has the same workflow as in PatternGen but with input for any alpha! I hope you'll like this!
Use it as you wish!
