The cave is wrapped in darkness and the rocks are very dense and heavy packed in a cylindrical shape,
it is a background that requires time and skill.
Especially when you have deadline, it seems that will be painful.
This page introduces how to draw such an esoteric cave with simple stroke only.

Draw a cave using a Rock Wall Brush
To clearly distinguish the difference of the light source here,
we use Rock Wall Brush ( both white and black) to draw a cave.
First, Draw a draft as a base.
The image will be concrete when referring to photos etc.
The rock wall brush (black) has two kinds of brush materials,
one for normal and one for cave.
First of all, Use the cave brush to draw the foremost side without a light source.
As for the cave brush material,
it is possible to draw a stroke like the figure shown below by default.
Remove the random check from the thickness pull down (blue frame).
* If you remove the check, the width of the thickness expands and you can draw parts of weak perspective naturally.
Stroke along the draft blue line at the front of the cave.
It is okay to stroke many times until satisfy parts come out.
When drawing is over, fill the four corners with solid color and emphasize the darkness.
Make a new layer below and stroke the line of the back rock.
When drawing the back line, reset the thickness setting to original (Random is selected again),
the thickness will become thinner and the perspective effect become stronger.
Create a new layer,
trace the outlines of each part in white to clearly show perspective effect.
Change the brush to the normal rock wall brush (black) for the next step.
Choose “Direction of line” and set the direction value to 90.
It became the same stroke setting like the cave brush.
Create a new layer below and draw the rock in the back.
Apply strokes along the draft and make it brighter as you approach to the entrance.
※It is OK to stroke many times until satisfy parts come out.
Change the brush to a rock wall brush (white).
Change the direction setting like before, and draw the entrance where the light hits the strongest.
Make a new layer below and draw the ground.
When drawing far parts,
a natural perspective will come out if you lower the thickness value.
Change the brush to the rock wall brush (black) and stroke the middle part.
Change the brush to a rock wall brush (for black cave) and stroke the foreground at the front.
Although the whole drawing has ended, it looks noisy in appearance.
To finish the drawing here, clearly divide light and dark.
The blue part becomes the darkest part, the red part becomes the brightest part.
Use a brush or tone to add a shadow to the blue part and a white to the red part.
※Soft cross-hatching brush used
Further emphasizing the “bright parts” and “dark parts” by overlapping tones.
It became a clear viewpoint that leads to the light of the entrance.
You can draw a cave which the light source is reversed.
If you are able to master feature of each rock wall brush materials like this,
you can draw heavy rock assemblies in a short time and efficiently,
anyone can draw up revolutionary speedup.
Please give a try.
