Source description

Based on hunyuan video wrapper by kijai.

Update 1/1/25

This adds device selection nodes to hunyuan video wrapper.

I have included the workflow.

AND there is a download for the changed files if you want to just manually replace the 2 files in /custom_nodes/Comfyui-HunyuanVideoWrapper/

Or you can download the git from here.

https://github.com/MrReclusive/ComfyUI-HunyuanVWMultiGPU

This has be recoded from the last version to make this all optional, so I could get the pull request approved.

so this IS coming to base hunyuanvideowrapper.

I've modified the nodes to allow selection of device for those with multiple gpu's, this was necessary for me as my system has 2 4090's on a 1x pcie switch, so unloading and loading was slower then generating, with 2 4090's and the 4080 I don't have to unload anything during generation anymore.
