Is liquify brush supposed to be different than the liquify transformation on result?

[acc4]

By liquify brush I mean the brushes that use the deform engine, such as ‘v)_Distort_Move’.

Should there be any difference on quality or something else on result tho compared to the liquify transformation?

I found the brushes to blur the pixels quite a lot so if that is what you are going for then that works. I use the transform liquify with small steps, which seems to keep most of the integretity of the liquified layer after distorting.

Although it still blurs pixels slightly and sometimes has odd aliasing. Most of the time it is effective though and I sometimes use it to help tweening in my animation.

Would be intesting hearing from a developer @tiar

Or maybe @AhabGreybeard or @Takiro, do you guys know any more in depth about this?

Anyway, sorry for the ramble

From my experience the deform brushes work basically like the smudge brushes but with more complex smearing effects (like concarve or convex effect), they are much simpler in their algorithm, less precise and therefore blur more, like @Komorebi wrote.
They are mostly to fix little details in a quick way.

With the liquify transform Krita will try a lot harder to keep quality by actually transforming the pixel matrix instead of simply smudging things so that it kinda looks like it was transformed. Its slower but more precise, I usually use it to apply textures to uneven shapes when the texture needs to stay in tact (like a tattoo or a Cutie Mark).

I know close to nothing about liquify so I’ll leave it at that.

@Takiro is correct, but also please note that you can disable smudging, then the brush will use only the existing pixels, which looks quite fun.

But it’s generally considered a “quick and dirty” way of doing transformation; it’s nowhere near the quality Liquify have.
