Unsample node result

[fraxcom]

Hello BlenderNeko,

I encountered a problem with the unsample node, I followed the example you gave in example_unsample.png, but I didn't get the same image after unsampling and sampling.

Here's

We ever spoke. I was using your nodes to work on a video workflow and inject diffusion partly from frame -1 (unsampled) into frame 1 (for consistency improvement). And you told me there where a problem with the unsample; maybe it's the same thing?

Thank you !

unsampling requires both the sampler and unsampler use very similar and very low cfg scales (somewhere between 1~2), when cfg is too large they start diverging. There are more complicated methods around that address this, but I haven't had the time to implement those methods.
