ComfyUI templates tutorial: sketch to 3D and video

Doug demonstrates how to reuse ComfyUI templates instead of building a workflow from an empty canvas. He finds blocks through comfy.org and the template browser in ComfyUI's sidebar, then copies and connects them for a toy character project.

The sequence starts with Nano Banana 2, which takes a drawing and a creative prompt prepared with Claude to produce a character image. Doug adds a turnaround views template, then feeds image data into an image-to-3D partner node to generate a mesh. He says this step does not require Blender or Maya.

For the toy box, he takes the Nano Banana Pro node from a magazine and cover packaging template and adjusts the prompt with Claude. The final stage uses the video model identified as FLUX 3 Video in the supplied description. Doug feeds it one image to produce a multi-shot commercial, with the generated spot included as the example.

The tutorial focuses on assembling existing blocks and changing prompts or models. It gives a short tour of the connections rather than a detailed installation guide. It covers template assembly rather than model installation or offline inference.
