Complex parametric textures may not be made with procreate, but don't worry, we can draw with black and white maps.
The first step is to search for the parametric texture picture you need and save it and import our photos.
The second step is to make sure our picture is black and white.
The third step, three fingers down, select copy.
In the fourth step, we click on the layer and select the mask.
Step 5, select our mask layer.
The sixth step, three fingers down, a key paste.
Step 7, the mask only shows our white part, the black part will not be displayed.
Step 8, invert our mask layer.
In the ninth step, we found that the edge was not buckled clean, indicating that the black part was not pure black.
In step 10, we select the curve in the adjustment tool.
In the eleventh step, we will move the point in the lower corner to the right, turning black into pure black, and finally we can perfectly buckle the parametric hole.
An additional small knowledge point, adjust the liquefaction in the tool, can also make our hole complex deformation yo.
