Hello,
I searched how to understand how work the Stiches Straight dynamics stroke on Substance Designer for Substance Painter.
The only official documentation we have is this: Substance Documentation really cool for create gradient but It was not my goal :) but that helped me to understand what I need.
So first step we need to create two integer variable :
stampIndex and stampCycleCount.
the Substance documentation is clearly about this two parameter :
The StampIndex is the ID of an individual stamp inside a brush stroke. By default it starts at 0 and increase by 1 for each new stamp. The StampCycleCount is a way to limit the amount of unique indexes and tells Substance 3D Painter to recycle/re-use the already generated Substance graphs. When the current ID reaches the limit Substance 3D Painter will start again from 0, creating a loop.
stampIndex just need to be create, value min/ max / default are not importante
stampCycleCount is important in this case I don't want to loop too fast, so 20 it's good value for me.
Now If I observe the Stiches Straight dynamics stroke on Substance Painter I see two important thing : the patern is not center, and when I draw the complet patern appears gradually. I conclued that the pattern has an transform when I draw
I created simple rope material ( base color, normal, height ect ... )
at the end I used transformationation 2D node with function for scroll thepattern on the -Y axe:
copy and past the transformationation 2D node for all maps ( normal, height ect ... )
Important thing to know : the height map is neutre if the color are grey 128
and in my case I need to add alpha on the diffuse.
I exposed some parameter of my materials and done :
Don't hesitate if you have question :)
