Neon Sign HDA
Houdini HDA to create neon signs, based on a single image input. Had to force myself to finally stop making images to process, and actually get around to posting this thing.
Input image vs output result. Alpha channel drives the tube creation, and the color channels are projected onto the resulting curve to set the neon color.
Drag and drop generation of signs just by switching the image inputs. Sped up slightly to cut down on video length, but less than you'd think.

Unreal Interface. Many controls available in the Details panel, mostly untouched for this demo. Randomization seeds, cable and neon tube controls, UV tiling, etc.
Signs created with the tool.
Frame paint color is created by sampling the most used color in the neon tubes, and offsetting it in the material by 50% to get its complement.
