Hello all, I was wondering how is it possible to increase the intensity of which the alpha is applied on a bigger brush.
This stroke was done with that brush size, however I would like to increase my brush size and keep this alpha spacing. Right now it increases the distance of the polypaint applied if I increase the brush size. Looked in alpha and stroke menus, I am lost 
Iām uncertain of what youāre after here. You can adjust alpha intensity in the Alpha menu, but I donāt think that is what you want.
The Alpha is the alpha. Itās not procedural. Itās a 2d image youāre applying with a brush. There is no way to change the relative āspacingā between elements in the alpha, except on a global level (making it bigger or smaller), without changing the alpha itself. If you make it bigger, the spacing will increase between those lines, and the lines will become larger in proportion.
You can, however set the alpha image to ātileā or repeat itself on a stroke in the Brush> Alpha and Texture> ALpha Tile control. That will make for denser coverage.
If you change the stroke type to a Spray stroke, in the stroke options you will find variable elements such as color, size, and placement jitter.
yes, the tiling what i was after
