Pencil Pro is the most sophisticated drawing emulator - period.

Unlike other converters (which essentially use a simple material trick), Pencil Pro is far more detailed and realistic. It achieves this by simulating how someone would actually draw!

Where should the pencil strokes be? In which direction? How hard should the pencil be pressed? How will cross-hatching work? What about shading? Where is detailed needed/omitted?
Pencil Pro handles all of these decisions. And oh ya... it can do this uniquely for every single frame completely on the fly!

Works with larger objects as well :)



This one is just to gloat...

What's The Secret

The secret that set's Pencil Pro apart from the typical smudgy charcoal product is threefold:

1) Believable drawings come from the combination of shading and general pencil strokes. Pencil Pro accounts for both these passes:

 +  = 

2) A real drawing is drawn in screen-space! It's that iconic '2D look' that isn't just grunge on a 3D mesh. Pencil Pro uses screen coordinates. A bonus of this approach is you never run out of shading detail - zoom away!  

3) Pencil strokes should generally follow the curvature of the object. Pencil Pro looks at the actual edge flow to approximate this (here is an exaggerated example):

Here are all 3 principles at once:

There are many benefits to this approach so I put together a rapid-fire FAQ.

Does it work on any mesh?
Yes.
What if the mesh is animated?
Yep.
Multiple objects at once?
Yes.
Is it fully procedural?
Yessir.
Can I tweak the settings for a new look?
Yes.
No UVs needed?
Correct.
With any lighting?
Yes.
Should I buy Pencil Pro?
Ya.

How To Use

Installation

Install Pencil Pro just like any other addon (for Blender 4.3 or above). Drag the .zip right into Blender and hit ok. Menu can be found in the N-Panel of the 3D Viewport.
