I have color in one layer and lighting/shading in other hard-light layer.

How is it possible to use smudge on these two layers without destroying surface color/lighting decomposition ? I had successfully used it for feathers when both lighting and color were in one layer, and I had successfully used hard-light + base color layers for smooth surfaces. But got problem when want both (smudge and layers decomposition)

you could use the liquify mode in the transform tool on the group.

Thanks, this is good tool, I am sure I will use it usefully in future.

I have checked it, it works for multiple layers:




But this move tool is not replacement for smudge, there is a lot of differences in result. Most significant — the move tool can't move elements of pixel-size, so it is no way for fur/fluffy feathers

Also the move tool works more slower (even on fastest Core i7 even with small elements of small-sized 500x500 images, OpenGL setting unrleated),

And it gives some strange artifact (coarse mesh grid? extremely large texels? don't know):

Seems, it is totally unapplicable on my current 5000x3000 canvas with 200px sized liquify brush - 5-10 seconds lag with unpredictable result (even with mouse).

I have tried to use "move tool" on each layer independently.

Default "move tool" as standard brush preset has discrete motion, with motion unit about 5% radius of the brush radius, which is too coarse.
When "spacing" parameter of "move tool" is set to minimum... it starts to erase image (makes it transparent).

Every Krita tool except simple brushes and layering have unexpected issues :/
