Landscape Paint square

please see my picture in the Attachment and you see the Square Landscape Painting.
Is it possible that i can Paint Smoother so that i cannot see some Squares?
Kind regards,

Hi halobungie,

Lower your paint tool strength, which can be done in the landscape paint settings. Additionally adjust the falloff of the brush and make judicious use of the smoothing tool to allow you finer control of material edges.
