Fastest way to create brush from selection?

[Vantika]

Hello,

I'm currently following this texturing tutorial. He uses Photoshop to create brush presets from selected grass patches, so he can later stamp them randomly across a grass background.

I know you can create image and intensity brushes to stamp custom images, but this involves preparing every single brush on the canvas and export and then reimport it.

Right now I'm putting each grass patch into a layer and later copy a desired patch into a main layer for all final positioned grass patches.

I just wanted to know if there is a better faster way to do this which I haven't found yet.

Thanks!

The only way to create brushes in Affinity is to export as a PNG and then create a brush using the exported PNG’s as the brushes pattern/texture. I hope they change this sooner rather than later.

You could use the export persona to quickly export all 4 brush shapes to PNG files

Then create a single intensity brush selecting all 4 PNG files

Using that brush will then create a random pattern of each of the 4 shapes, selecting just one PNG "file" at a time.

The brush preview will show you which shape is the next to be painted, so you can decide where on your canvas you want to paint it

If you need a specific shape for a particular area of the canvas which is not the one shown in the brush preview then clicking off canvas will select another random shape

Thanks, that's what I did. I'm glad that brushes are persistent across projects. Put them all in once and never care again.

Thanks, that will speed up placement immensely! If I may ask another question:

Is it possible to set the random rotation to a certain range? I would like to limit it like in the image below. In brush settings however it's only possible to have the rotation clockwise and no way to set the initial rotation counter-clockwise.

 

Right now I'm using mouse drag rotate but since I have to switch to Resize mode every other second and there are lots of patches to be placed, i's really a pain.
