I think there's a problem with "skyreels_hunyuan_t2v_fp8_e4m3fn.safetensors"

If the original bf16 precision file is downscaled to fp8_e4m3fn precision within ComfyUI, it runs normally.

However, when using skyreels_hunyuan_t2v_fp8_e4m3fn.safetensors, a black screen is displayed.

Hmm that's odd, I double checked by downloading the file myself, and it seems to work fine. Maybe your download somehow got corrupted?

same problem, bf16 to fp8 runs normally, but download fp8 can't use

the fp8 model works for me - no black screen issue

Works for me on 4060 Ti 16GB VRAM, with --use-sage-attention, triton installed, both compile_args inputs connected to Torch Compile Settings node output, quantization set to _e4m3fn_fast.
I remember having black screens in video renders before Skyreels when I ran on an outdated ComfyUI version. I then downloaded a new version with embedded Python and made sure I had the latest Kijai nodes and Hunyan wrapper nodes.
