Yeah, I know, neither this nor the script boards are for request, but after digging through approx. 200 different postings, I give up being smart and ask the dumb question:

has anyone made a strict "underwater" post processing shader yet? With dostortions from the water movement and refractions?

thats a real nice vid but unfortunately not what I need. I`m talkign about a post process shader that simulates the visual distortion underwater and has perhaps some particles flow also (the later one isn`t absolutely necessary)

Combined with Bloom AND lightrays would be best, but I can unify the shaders on my own, if necessary

Edit: I have now taken a deeper look at uzi-idiots refraction fx, as I have DarkShader installed, i guess i can tinker something that fits...

Edit 2: No, I can`t

I think you mean something similar to what the old Corvus mod used to have. Was an awesome shader. I have also been looking for something like this for awhile now Ertlov. I don't think one exists other than the shader Dark Goblin used for his old mod. I could be, and hope... I am wrong.

I can do it for you, there wouldn't be much to it really. You just need an effect kinda like looking out the windows in Bioshock? Where everything is just wavy and distorted?

As far as I got it you are right, bond1. Probably you could put in some color correction, too.

OK, basically I need two different components. The first would be the mentioned wavy distortion (of course dynamic and if possible good enough commented to tweak it on my own), the second one would be the particles floating, with varying sizes so that you have the feeling some are far away and some are near. I tried something with filmgrain, but it doesn`t look that good

And I would be VERY grateful if i got it once with bloom and once with surreal inside.
You just need to tell me what you want for your work...

As for color correction - right now I change the ambience light setting depending on the players depth which works acutally not that bad. Don`t know if it would be better to have 30 different PP shaders being switched depending on the players depth

And out of curiosity - did you get any of the 2-3 mails I sent you during the last 8-10 months?

Nah I woulnd't charge anything for it, I'll just release it here.

I don't know how I would accomplish the particles you describe in a post shader, I would think that would be suited more for a particle effect. But the wavy refraction is no problem (maybe with an underwater tint option?).

It will be next tuesday or wednesday if that's ok, I'm tied up at work this week (plus I need to brush up on how I set up the post shaders, it's been a while since I messed with them!)

I haven't had a whole lot of time to devote to FPSC this past year, so it's very likely I missed your emails completely.

EDIT: This shader will need to load an external texture for the refraction. I've only provided one empty "slot" in FPSC for a shader of this type called "multi.fx". We have a couple of choices if you want multiple versions of this shader. You can simply replace one of the existing shaders that use external textures (like rain or gasmask). OR...I could add more slots to FPSC to allow more shaders of this type - I would just need to add it to the source, which is no big deal.

Replacing gasmask would be totally ok, so NP on that.

Yeah, that would help a lot.

Well, i thought so, too, but with v 12002 particles dont work anymore on my side.

yes, of course.

Ok one more question: Is this shader meant to be used underwater in FPSC? If so, I really don't need to add a tinting option, since water fogging is already available via scripting which tints everything.

no, it doesnt tint shadered stuff. At least not static entities and segments with your shaders applied to them...

Bond1,

Are You Serious?!? That looks awesome and it looks like you did it in 22 minutes from post to post! Do you do this for a living or are you some kind of god among programers? If I could ask where did you learn HLSL? I have DarkShader and can get things working in that, but I can't quite get them FPSC ready unless I start with an already working one and mod it with DarkShader.

Bond1: That is awesome! Could the same be done to a dynamic entity, ie. a transparent window. To get the effect that you spoke of (Like the windows in Bioshock)? This is something I've been wanting for a long time to get my "Nautilus Sub" worked out. "Will pay!"

I just need to plug it into the bloom shader. I have an idea for the particle "floaties" that might work as well. Like I said earlier, I'll release it sometime next week. I'll build in controls to vary the speed and amount of distortion so you can alter it to your needs.

Quote: "

A entity version of the shader would work too, you could apply it to a window with an image of the ocean in the background, only you wouldn't get any parallax, so it would be best to keep the ocean texture pretty simple without any major up-close details to ruin the effect.

Had a bit more time to try out the particle effect. It turned out even better than I had hoped! Now there are random, underwater "floaties" that waft around - some are near the camer, some father away.

Check out attached video.

Really nice shader I could think of some nice uses for this. How does this look when you move around?
Even as it is that would make a nice damaged helmet filled with water death scene, I can feel an Atlantis vibe coming on.
Strangely enough I was planning an underwater level.

Awesome! Its one of those threads.

That is true you're not going to move THROUGH the particles using a post-process technique. With the constant movement and amount of distortion it doesn't totally ruin the effect unless you're focusing on one particular particle -which is really difficult when you're moving around.

But I'll include controls vary the amount and opacity of the particles.

Are there any scripting commands to detect if the player is underwater? I'm not sure of Ertlov's intended use, but otherwise you'd just set up a trigger zone like any other post-shader.

@Cosmic something like this?


I don't wish to steal Bond's thunder, but I believe this was what he was talking about for a shader. Below is the files I used to get this effect. I edited a shader in dark shader for this effect. I was playing with it for Cp's new western pack. Enjoy!!

Yes or something simple behind the glass where the cannot go. In my case here I used the Bond's containment room as a barrier as the glass has no collision.

Attached is the underwater shader with integrated bloom.

Check out the video here, watch it at 1080p in fullscreen if you can: http://www.youtube.com/watch?v=Jn-ccrx64S0&feature=youtu.be

You can tweak the shader by opening it up in notepad. Here you will find "waterspeed", "refractamount", and "watertint" variables that you can alter to suit your needs. Also, you can alter the particles texture if you wish with your own - or set it to completely black for no particles. You can experiment with your own normal map for a different refraction pattern as well. NOTE: you cannot view this shader in Dark Shader because Dark Shader does not load external textures for post shaders. Any changes you make you must view in FPSC.

Enjoy - I'm really happy how it turned out!

@starmind - shader works great. thanks

@bond1 - Nice addition to the arsinal of shaders. Why is it that one cannot just copy and change the name of the Post shader and change the texture to it. I see texture assignments in the code in notepad. But when I try changing it, I get an error that the shader cant find the file or it just uses the texture that was made with it.

Example: Filmreel Post process shader. I wanted two versions in the same level with different decal textures for a slightly different effect. Copied filmreel.fx to Filmrewind.fx. Change the texture name to film_rewind instead of Film_scratches in the fx file.

But still looks for and shows the original texture. when I change the name of the original texture, then I just get an error the shader cant find the original texture.

any ideas?

No problem.

There is one other control that may be useful that I didn't set up a variable name for. While you can control the opacity of the particles by altering the texture, you can also do it directly in the shader. By default, it is set to 5% opacity. Find this line in the shader and change the 0.05 value to something else to alter the particle opacity:

float3 final=lerp(MaxAmount, ScreenMap, Luminance)* watertint + (0.05 * Particles) ;

Because fullscreen shaders that require external textures need to have them loaded and defined explicitly in DBPro. Other fullscreen shaders that just use the screen itself as an input don't have this requirement (like bloom). You can freely name these type of shaders whatever you want and use as many as you want.

But for post shaders that use external textures, you can't do this. I have provided one "slot" for users called "multi.fx" that can use two external textures - and this is why I named the water shader in this manner - to use the one user-defined "slot".

If you'd like, I can add more slots to the source code. How many do you think most users would need for a typical game? I'm thinking 3-5 for most FPSC power users.

Thanks for the reply.
I see. it was driving me crazy.

Instead of adding more slots, Could I call a different version from another folder in the effectsbank, say postprocess\post2?

Thou, more slots could come in handy.
