I’m making an app for android. How do i desaturate WebCamTexture? I don’t have the Pro license and i need to add normally coloured objects on top of the WebCamTexture (meaning i’ll be very reluctant to desaturate the whole screen).
As it’s a texture, you can desaturate it inside a shader. Something like (r*.25 + g*.5 + b*.25) / 4. I read somewhere that green (not blue!) is more important for the grayscale, but / 3 would probably do as well.
If you’re displaying it with GUI though, you’ll need to to modify the pixels of the texture with Get and SetPixels. The process is more expensive however.
