What is the best way to simulate a 64color display?

Hello vvvvorum.

i need to simulate a 64 color display. I want to specify the 64 colors by myself.
I have an existing scene as a texture.

A quick search in the textureFX-folder i couldnt find a solution…

any ideas, tips?

of course i can do a manual mapping with pipet or shader but i thought someone must have done sth like this before?

thank you,
alex.


Maybe?

thank you björn,

lutz is cool, and probably its possible to use it to decrease the amount of used colors. as i understand the technique right, i have to create a texture with the desired fx(eg. 64colors) and feed it into the filename-LUT - pin. but its not working as expected. it creates gradients with colors im not using in the LUT-ctrl-texture… maybe im simply not able to set it up properly :/

any other ideas?

Not the most efficient approach because of loops in a shader + doing all iterations for each pixel, but readable and may give you an idea …

Dither Pre-Process also helps a lot, maybe even downsampling the texture using its UseDefaultSize Pin.
