In the next steps you’ll smear and blur the paint on Dino. Smearing with a Paint Effects brush blends adjacent colors together along the stroke path. Blurring softens the edges of adjacent colors by averaging their color values.
To smear and blur with Paint Effects brushes
In the 3D Paint Tool settings, under Paint Operations settings, observe that the Paint Operation is now set to Paint Effects Smear. The brush you selected, cleanWaterDrip, has settings that turn on the Smear setting automatically for you.
