<h3 id="but...-why-av666ffp2">But... why?</h3>I created this workflow because I thought I had pushed the limits of what Hunyuan 3d-2 could do, and someone stepped in and proved me completely wrong. Because of this, I fell through the rabbit hole in discovering what hy3d-2 was even capable of. I believe that even their demos did not understand that their quality could be significantly better.<h3 id="base-workflow-9ymwvxi5o">Base workflow</h3><a target="_blank" rel="ugc" href="https://github.com/kijai/ComfyUI-Hunyuan3DWrapper">The base of this workflow belongs to Kijai. </a>Please visit his github for instructions on how to get started.<h3 id="what's-different-orbjva2yy">What's different?</h3>Kijai provided a great start, and I was able to build on that. It turns out - the 3d modeling part comes quickly and easily. The difficult part is texturing properly. I took a long time finding the correct camera flows, and how to upscale the textures so when they are painted on, they look significantly better.Reactor: allows a character to keep facial features.Ultimate SD Upscale - This allows me to push the texture to its limits while not being too liberal with changesGeneral upscaling - larger sizes are painted on, which allows a much tighter process.More Camera Angles - The way it works is multiple camera angles are selected, then it bakes them all in. I went in and added a few more, and optimized the rotation around it to what I thought achieved the best results.Granular approach - you can control how many vertices are on the object, and how big the texture turns out to be. a high res object is 3-4 MB and a low res object is more like 1MB. This means things like game assets can be kept small if necessary.Extra Shenanigans - Mapping the camera angles is very VRAM intensive, so it's difficult to get a high resolution. However, I was able to split the camera into parts, allowing larger resolutions, and thus more accurate texturing.PC specs - GTX 4090 with 64 GB RAMTime to generate - About 20 minutes, but significantly less if you decide not to upscale.

Hunyuan3D-2 + High res optimizations

I'm currently tweaking it to look the best regarding humanoid generation, because that is the most difficult to do. There is a lot of give and take, but so far, this is the best I have come up with.
