Adding a Transformation Mask----------------------------* First add a transform mask to an existing layer.* Select the transformation tool.* Select any of the transform modes in the Tools Options dock and, with the transform mask selected, apply them on the layer. * Hit apply.* Toggle the transform visibility to see the difference between the original and the transform applied... note:: Affine transforms, like Move, Rotate, Shear, Scale and Perspective get updated instantly once the original is updated. Other transforms like Warp, Cage and Liquefy take up much more processing power, and to not to waste that, Krita only updates those every three seconds.To edit a transform, select the transform mask, and try to use the transform tool on the layer. The transform mode will be the same as the stored transform, regardless of what transform you had selected. If you switch transform modes, the transformation will be undone.
