%%%--- Operating System, Graphics card ---
win7, nvidia gtx 560ti

- Blender version with error, and version that worked ---

error in version r56782

- Short description of error ---

Paint strokes with texture mask and rake enabled produce different in 3d view port and image/uv editor

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

in the image file (issue.jpg) attached

a) is a paint stroke drawn in the 3d viewport
b) is a paint stroke drawn in the uv/image editor

they have the same settings but appear to produce different results.Blend file attached with packed texture

%%%i'm not sure if its an issue of how much you zoom in or not.

but at one point it was consistent no matter how much I zoomed,then when I changed the texture image,i got strange results.I can't be sure what the correct behavior is.%%%

%%%Closed duplicate report:

There is a bug here indeed, the texture size should not depend on zoom.%%%

%%%I don't know if its of any use,but I forgot to mention I was using a wacom tablet stylus.%%%

%%%but brecht,I don't think the problem is solved,are the brush strokes supposed to be effected by the zoom in the 3d viewport too?

what I mean is,if you have two windows open (3d viewport and the uv/image editor) and texture paint mode enabled in both of these,if you then then change the brush radius inside the 3d viewport,you will see that the brush radius size updates in the image editor too.So why is that,the brush size doesn't appear the same when working in both.

this was the main concern of this report.and thats what I meant by the brush size not being consistent between the 3d viewport texture mode,and 2d paint texture mode.

maybe i'm not being clear enough?

%%%In the image editor the brush size is relative to the image, like e.g. photoshop or gimp. In the 3D viewport the method used is projection painting, where you're kind of painting on the viewport and that's projected onto the 3D model.

That's intentional behavior as far as I can tell, they're different painting paradigms. It could be useful if there was some option to paint in 3D with a fixed size in texture space, but that would be a new feature, and is not so obvious with arbitrary UV mapping to the 2D image.%%%
