Gp_Mesher
Just drop in this one Geo Node and turn your Grease Pencil drawings into 3D meshes!
If you're brand-new to Blender and want to see your drawings in a new light, just follow the step-by-step instructions included in the file to jump in right away! If you're a Blender old-head, then append this group node into your work file, and open up the tabs in this node group to find all the remeshing options you need to fine-tune exactly the look you want.
Easily use one node to mesh your entire GP animation, or combine multiple to easily separate your layers for fine-tuned positioning, different material application, and way more! Lots of inputs means lots of potential for interactions with your existing node setups, or keyframe different values to see more deformations.
