Landscape painting using grid lines instead of smooth brush


I want to start with I am very new to Unreal Engine and this is for a course I am taking in college. I am trying to paint a material onto the landscape but when I paint it seems to use a grid instead of a smooth brush. I haven’t been able to find any settings that I have changed which would relate to this. The only thing I changed when it went from smooth brush to grid snapping the paint is adding a texture sample to the material instead of using RGB.

Thank you!
