For those curious, the character was modeled, UV'd, and painted in Blender. The line art was made using Blender's grease pencil tool. Most of the lines were drawn on but some were made using grease pencil's line art modifier.
05. Manually cleaned up the line art in CSP. The rougher the line art output by Blender, the more labor intensive. Made this mistake before going back to get a better rough. Making changes to 96 frames adds up real quick! 06. Took the img seq back to Blender to render video.
For those interested 01. The GM II was modeled, UV'd, and painted in Blender. 02. The rough of the lineart was made using Blender's Freestyle 03. The bleepbloops were made using Blender's Grease Pencil. 04. Rendered the anim img seq in layers to be imported in Clip Studio Paint.
The character was modeled, UV'd, and painted in Blender and the line art was made using Blender's Freestyle. I don't know where the jigglypuff came from.
For those curious everything was modeled/UV'd in Blender. Fspy was used to approximate the perspective. The original image was projection baked onto the models and repainted in blender/PS. Some parts (the floor tiles/images on signs) use the unaltered bake. Freestyle was used for the line art.
03. Anim'd the cam & rendered out several img seqs of diff scene elements. Went with 3s at 8 FPS. It's economical + CSP only lets you render 24 imgs. 04. I imported the seqs into Clip Studio Paint, cleaned up/added line art as needed. 05. Colored each frame! 06. Rendered it out and posted!
01. I made a 3D model in Blender, sticking to the reference image as closely as I could. 02. In the past I've used the inverted hull method to make outlines. I couldn't get a nice textured look to it, so I used Blender's Freestyle instead.
