I made an animated brush with 360 layers.
AFAIK the Ranks equal the number of layers.

But when i set the number of Ranks to 360, it always goes back to 100.
Is 100 Ranks the maximum you can have ?
Is this a bug or am i misunderstanding how Ranks work ?

Thank you. I was aware of that link you provided from the manual (which is btw broken in your post), however im having a very hard time wrapping my head around it.

So if i want to create an animated brush with 360 layers and the angular option, what is the correct number of Ranks ? One ?

My brush seemed to perform as expected with 100 Ranks, although i wanted 360.

EDIT: I think you confused Ranks with Dimensions.

I'm currently running tests, and ranks seem to be per cell, why there is only 100, I have no clue.

It appears I have no dimensions (faulty GIMP?) Every rank test I run it defaults to the last row of my brush.

@mahvin: i just looked at your chain brush and it has 72 ranks, the same number as the cells, aka 72 layers.

Yes, a rank appears to be a cell number.

But only if you have more than one dimension ? Thats one way to read the manual.

EDIT: no thats wrong, Ranks must equal Cells.

Here is a teststrip i made



When i set Ranks to one, it doesnt follow direction, but when i set it to four it does.



Same result when i have layers instead of a single strip.
For some reason Ranks is limited to 100, so i guess its a bug.

I realized that dimensions require a little more thought, but ranks are number of cells. Also, I can't run incremental first if I'm using more than one dimension, it just runs my last row of cells, every single time.

EDIT: DING DING, the bell went off.



I've been thinking dimensions all wrong. GIMP has requirements in how our 3D will be accepted. L/R

So if i want to make a brush that has 360 cells (i want each brushcell to be rotated by 1°, because i need a very precise brush), can i split them to more than one dimension ?
100 cells to dimension 1-3 and the remaining 60 to dimension 4 ?

Not what I am saying at all. The 3D array model GIMP uses require users to keep the cell layers in sequence, if you observe the layer model for the hands more closely, it follows a specific standard for the dimensions they are providing as the example. Angular has to show angles in cells, which is TOP to BOTTOM. In the second dimension it goes to incremental, in a LEFT to RIGHT direction (cells are only 2 across, so it picks 2 cells incrementally) and finally 3rd dimension is random which is also LEFT or RIGHT, it picks either the BLUE hand or the BLACK hand.

Angular is only TOP to BOTTOM in their example, you could also make it go LEFT to RIGHT. Anything beyond a simple one dimension brush will require fewer options in order for the pipe to choose between them effectively, like YES or NO or BLUE and BLACK. One dimension pipes don't need anything to choose from, so the cell layout can be however you like it. When it comes to using more than one dimension, your layout must work within the boundaries of the selections you're using. It's interesting that they have 3 dimension selections just for pressure tablets and pens.

Words in CAPS are for emphasis, not excitement or exclamation.

Not really following this, but as a test I made two rotating brushes. One with 72 frames and one with 360 frames. There is an obvious difference between the two. On the 360, I set 4 dimensions- 100, 100, 100, 60.

I don't know if this is what you want or not.

Note here:



L - R - L - R - L - R - L (incrementally)
90 - 90 - 90 - 90 - 90 (angular)
2 blues 7 blacks 2 blues 1 black 1 blue (random)

If you give the pipe (array) too many options (cells) to choose from, using more than one dimension, you need to limit what those options are.

Im still lost with this problem.
Maybe i need to try the hands example.

But if Ranks is limited to 100, then i guess its not possible to have 360 layer/cells with the angular option.



What i want is a brush that follows direction, with a rotation of 1° per layer/cell.

On a one dimension brush you can. It will follow the angle of each cell. All 360 cells.

umm...but i cant set the Ranks to 360, because the maximum seems to be 100...
doesnt that mean im limited to a rotation of up to 100° ?

I apologize. I thought you said it worked in spite of it. When I use incremental it just follows my cells from beginning to end.

How do i make a bug report, so somebody of the programmers can fix the maximum Rank number of 100 ?

I made this brush a long time ago (2.8) by following tutorials here:

(Image Pipes, Image Pipes 2)

It shows a use of Ranks.
