I have started adding Post Processing effects into the source code of CopperCube rather than an Action as:

- The Action framerate cant be adjusted
- Any hue/color change also affects the 2d overlay colors
- Any moving PP also screws the 2D overlays position

I have added some tonemapping stuff so far and its working...
will take some time to add the rest in...

Congrats, looks like you finally figured out how to swap out the original binary in the engine!
I’ve been doing the same thing - I’m using version 6.4 but with a custom rewritten binary, and it’s super convenient (especially when working with versions older than 6.7).

Cheers Monks and thanks wing.

Yes, I must be getting slightly better at that horrible language we know as C++ as before couldn't work it out.

Now I am able to send through time (like iTime from shadertoy) and also load and apply 3 textures like in my Action that the shader can use the same way to modify texture co-ordinates.

Its all been added now and works except for the rain shader as that one is too large to fit in the limted size allowed with shader model 2.0.

Will give an update when fully done and itchio is updated.

The source code has been updated with around 30 post processing shaders - some like before with some new ones added in.

2D overlays wont be affected now and multiple shaders running together should work better than using an Action to run it.

You can get it as normal on itchio for those already paid for no extra cost (like almost all of my updates).

Itchio is updated with the missing textures needed for some shaders to run right just now.

They are in the data/images folder and your exe needs to have that as a sub directory to run those shaders that need the textures to run.
