[solved] LTXv 0.9.5 green output? it's command line -use-split-cross-attention or --fp16-vae is incompatible

LTXv 0.9.5, 1080 Ti 11gb, green tiled scrambled output

The bad output was a result of my command line argument: -use-split-cross-attention or --fp16-vae and I am guessing "--fp16-vae" is causing the bad output.

Hi, I'm having this issue but i just don't understand the solution presented. I've tried a different VAE same result. and the command line part just goes over my head.

Thanks, this green static issue was driving me crazy but this fixed it. @TripStan79 go to your ComfyUI folder and edit run_nvidia_gpu.bat. Remove the "--fp16-vae" section, save, and relaunch ComfyUI.

Using torch.bfloat16 instead of torch.float16 will get the correct reconstructed videos.
