fade shaders/post effects

[DudeAwesome]

is there a nice way to fade in/fade out shaders or post effects?

 

 

like in some games e.g.

 

you are nearly dead and everything gets greyscaled.

 

for now it should be possible in this case to toggle the greyscale post effect but I would like to do it a little bit smoother.

 

can I push a dynamic alpha valua to shaders at runtime? I guess not.

I've been requesting strength control by code on effects for some time.

mhmm seems like I´m stuck here and noone have a clue how to solve that problem

I discussed that point with Rick some time ago, i don't knwo if it is implemented, but you should be able to pass script values to shaders, i htink there is a way to do that.

It makes sense, as anyone will want to have control and make dynamic full screen effects shader effects from progressive night vision, to damage to progressive coloring etc ...

how ? It should be possible with uniform vars but how I can define my own uniform vars ?

 

Like a dynamic Alphavalue calculated with leadwerks and pushed into the shader with uniform qualifier each loop?

You can use a global container class for such values and use them in the postprocess lua file. If no lua file is present you might need create one and modify it to your needs. As an exsample or starting point you can take a look at my pfx manager in the prefab section of the workshop.
