This is the biggest problem with making Brush Dynamics their own resource type, and from the end user's perspective, an unwanted regression compared to how 2.4 through 2.6 allowed you to edit the mapping matrix at any time. It's like if you went to the Curves dialog and loading a preset means you can't make further adjustments to fine-tune the graph. In the meantime, make sure you have created one New brush dynamics resource even if it's solely for the ability to edit the matrix. > > 6.

"Incremental" means that every application of paint in a stroke layers on top of the previous one. I recommend never using it outside special cases - most brushes have a spacing of 10-15% or so which means that any given pixel along the stroke area will end up 'painted' up to 5-7 times over. Normally this is a moot point but with incremental option this means that the opacity will end up being applied 5-7 times over too -- you lose the ability to get a stroke with a predictable OVERALL opacity value (even an opacity setting of 10%, if incremental, yields an end result up to 40-50% opacity). This is as technically correct as it is utterly undesirable, but it's a limitation in how GIMP handles painting actions internally so it's virtually impossible to fix. -- Stratadrake strata_ranger hotmail com -------------------- Numbers may not lie, but neither do they tell the whole truth. |
