Hello all,
I've always wanted a way to automatically make hair cards in Houdini using its hair grooming system and I've been working on one over the summer and just released the BETA version.
HAIR CARDS OTL [www.psynema.com]
The documentation is long but it's written for people who may not know Houdini well. Basically make sure your hair generate node has a hairclump node then plug it into my Hair Cards asset and experiment with the sliders. It needs to be baked in Substance Designer since that has a “bake by mesh name” feature - I made groups for each individual hair card and it's corresponding clump, so baking won't be a mess contaminated by all those hairs. Each card is baked together ONLY with its corresponding hair clump using Substance Designer's “bake by mesh name” feature as opposed to baking the entire high poly hair mesh to the entire hair card wig.
I'd love feedback and the asset is downloadable on my website link provided or it's also on Orbolt.
Last pic is rendered in iRay w/ Substance Designer. That's Houdini's hair grooming system baked onto low poly cards no handpainted touch ups at all.
