How do you convert a Texture 2D channel into a float?



I'm trying to unpack a video source colors into it's respective RGBA values, then merge it back together.
I went through the Wire documentation under Texture2D channels and TextureRGBA channels and was unable to find anything (unless I'm missing something).

I don't think you can. What are you trying to get? A float value for each pixel, or do you want to add some logic to a texture? (You can add/multiply/etc a texture with a float value)

I guess more so a float value for each pixel so I can manipulate individual RGBA value for creative effects. I'd imagine you could create some really cool stuff if you could do that.

That requires GPU to CPU communication. It's on the roadmap.
