[APh] Roll Brush (Deform The Brush Along The Stroke Curve)

Recommended Posts

Would love a Roll brush in affinity photo, which is a brush where your custom brush shape is deformed along the stroke curve. Here's a video of the Zbrush "Roll Brush"...

This is similar to the "Angle Jitter -> Direction", except this feature only rotates the custom brush along the stroke direction. The Roll brush actually deforms the stamp in that direction. This would let you create stuff like stitches on clothing, tentacles, texture on a tree branch, wires, all sort of things that are currently not possible.

That looks like a 3D modelling application.  Are you sure that would work in a 2D vector design app?

 

Yes, All it does is stretch the image. In the image above, it's using the stretched image to make a bump map, but it doesn't need to be used for that, it can easily just be used to make a 2d paint stroke. Think of a combination between a paint brush and the liquify tool.

That sounds really interesting!  I think the Affinity staff should definitely look into it.

@soulburn In what way is this different from the sort of image stretching that Affinity Designer already does along a path?

 

In the Brushes Studio choose Image from the dropdown.

because it stretches your image WHILE you are drawing the stroke, which allows for instant feedback. Stretching an image along a path has its uses too, if you have a situation where its something more machine like, but that technique is more like a careful construction project, this tool would be far more interactive and better for organic painting. Like if I'm doing 200 tree branches, I'd hate to carefully setup 200 paths first, instead I want to paint the paths and have the bark grow along my stroke as I go so I can instantly evaluate if I'm achieving the effect I want.

What you're asking is a mapped stroke.

Basically it is how Designer works and does it "live"...  :)

 

This is a sort of bramble I'm currently using for an illustration

 

I'd love to see raster mapped strokes in AP too.
