What are animated brushes? - OurJud - 02-26-2017
Can someone please explain what is meant by 'animated' brushes, as opposed to regular brushes?
RE: What are animated brushes? - Blighty - 02-26-2017
A regular brush is just one image.
An animated brush consists of more than one image. These can be set to display in sequence or randomly.

The Gimp manual is really good. You should have a look !

It stands for Gimp Image Hose, and it is a brush made up of several layers, which can be painted in sequence or randomly depending on how it is set up.
see: https://www.gimp.org/tutorials/Custom_Brushes/
there are gih brushes in the standard gimp brush set, look for the tiny red corner in the brush preview.

I see all the info about animated brushes except how to make the animated brushes be able to change color when you paint with them. I have tried looking up videos, but none of the seem to work when I try it in Gimp. I don't see that info anywhere else either, not even in the manual. Anyone? Thanks.

Same as plain brushes:
- if the brush is grayscale (Image>Mode>Grayscale) then it is used as a mask, the white is transparent and the black assumes the current paint color,
- if the brush is RGB (Image>Mode>RGB) then it is used as is, the shape of the brush being determined by the transparent pixels

When I create a New Image then, I should choose Grayscale? And what about the Fill With section on Advanced Options? Do I put Background Color or Transparency or what?
Also, when I make the new layers for this animated brush, do I copy the previous layer, or just add a new layer? Or does it matter which I do?
RE: What are animated brushes? - shellyhoward - 01-03-2019
To go into a little more detail about how I've gone about trying to make an animated brush:
This is what I have tried:
In File>New> I go to Advanced Options Then In Color space I choose Grayscale,
and in Fill with I choose Tansparancy. I have also tried Fill with< Background color.
The image that I start with is drawn in black.
I have tried adding new layers to draw my brush images on. I have also tried
copying the background layer for as many layers as I need and then adding my brush
images onto there.
Then I Export as a GIH.
Results so far: Every time there is no color to my brush image, or there is a gray background and still no color to my brush image.
If anyone could please explain the process of what you do step by step, it would be so appreciated. Thanks.

To create a new brush:
1) In File>New> I go to Advanced Options Then In Color space I choose Grayscale,
(or use the default RGB and then do Image > Mode > Grayscale)
2) The background must WHITE. (White will be transparent)
3) Draw in black or gray (black will take the foreground colour, gray will be semi-transparent foreground colour)
4) To create a new layer: Use WHITE for the background, draw with black/gray. Create as may layers as needed.
5) Save as .xcf ; Export as .gih
6) Put the gih in your profile brushes folder, refresh the brushes in Gimp
To use the brush:
1) Create a new image, this time it must be RGB
2) Select the brush
3) Set the foreground colour
4) (Most often: draw on a new transparent layer - make editing easier)
5) Draw
NOTE: If your brush is RGB it will not take foreground colour. No colours are changed, the brush is used as created.

Here is sample brush pipe file. Load in Gimp, export as a GIH:
- Spacing: 100
- Cells: 3
- Dimension 1
- Ranks: 3, incremental
PS: rereading your post, it is possible that in addition to being gayscale, the layers should have no alpha channel. There should be no transparency if you want a "cameleon" brush, tranparency is determined by the white.
