Dry brush and other filters
Now I start to add some 2D effects to knock back the appearance of the 3D render. The Dry Brush filter with Brush size 2 or 3, Details set to the max and Texture set to 1 is perfect for this. I play around with different effects filters, such as paint daubs, drybrush and cutout, and always work on layer copies, in case something doesn’t go according to plan.
Fading out layer effects
After applying a layer effect, some details may be lost. This is when multiple layers come in handy. With your layer still active below, use a wide, smooth and low-opacity Erase brush to remove some of the layer effects. Then duplicate both the original and faded effects, and merge them to create a new “ground layer” that you can duplicate to work on new effects.
