Rendering - Disable color

[Bedrock_Miner]

Hey guys!

 

I want to add a special block which renders the player watching it but with a colorless skin (saturation = 0)

 

How can I do this?

I actually have a renderer which renders the player exactly as i want but how can i disable the color??

Hi

 

I don't think there is any such command in OpenGL, I imagine it would take a bit of work with shaders which is out of my experience...

 

What I would do - take the player texture and create a greyscale version of it, either using the CPU or by using render-to-texture for the three channels with appropriate blending.

Personally I'd use CPU because I haven't used OpenGL render to texture before, although I'm told it's quite easy.
