IndieEffects: Bringing (almost) AAA quality Post-Process FX to Unity Indie

Eric the shaders don't have to be optimized, since I have pro and I have the profiler it is the cpu side that is performance heavy since shaders are done on GPU and the Scripts on CPU (Correct me if I'm wrong), the scripts are the ones that need serious optimization, I already have a list (Sort of) of what fuzzy or us that we need to include to the scripts to optimize.

1. Downsampling, this should be an Int variable and this effect degrades the RT resolution for performance.
2. Have a frame delay so ReadPixels or Resize doesn't occur every single frame,
3. Don't set values every single frame, set it once

BTW nice logo.

 

I think you should set values every frames, as the SetFloat function is not expensive (it's like a transform.position = ...), and it allows user to modify it in runtime (for example increase DoF in cinematic and decrease it smoothly, autofocus, make the screen more blurier or not when hurted).
However, downsampling and frame delay are useful.

 

I've also noticed that so I've begun that process in the new effects.

 

Thanks!
Wait do you have the pro trial???
Also does anyone have an example of downsampling?

 

@FuzzyQuills Are we allowed to use this in our project?? And do you have copyright or something on it?? Btw this is AWESOME!!! You've done a great job!!

 

Some of the effects are ported from shaders that I've ported. Or have taught how to others or made up. I could essentially do many different effects with Unity Indie but my focus has been on revolutionizing the unity renderer for now. (Unity Pro) If you want to know the legal stuff, check the references I posted along with the shaders I posted in many places on the web, such as on ArmedUnity.

 

Most do not have copyright restrictions. But you are not allowed to sell it as it is.

 

@WGermany Can you send me the link because i couldnt really find it :/// Thanks in advice )

 

@Eric2241 I was just wondering if its free for commercial use or not. Btw thanks everyone for the replies )

 

Can I ask when will be released date? Circa.. btw, can anyone make a volumetric fog similar to mirandas's fog?

 

We would need a shader; so if you could find one we could port it. Though miranda's shader is very performance costly; looking at his screenshots, its always a very small amount. I'm trying to port the global fog though it never displays the actual fog...I've done the correct process, but right now I'm trying to get sweetfx's hdr to work.

 

WOW!! Well Fuzzy Quills, that's so awesome, i'm gonna help some people in my facebook unity page by sharing this, this is awesome

 

Hi guys! looking good!

Sorry for the delay! the new version hasn't been out yet, as I have been a bit lazy, being it's the school holidays...

But not to worry! I am getting my coding and patience back up, and I am also taking a shot at building a linux OS myself, so while it is building stuff, I may also secretly (not really...) release the new one! All I ask is that all contributions be posted one after the other, wherever possible! also feel free to PM me the packages if you like.

meanwhile... although I have implemented everything frosty stated up top before, there is a problem with the downscaling ATM. because I couldn't do it with a single camera, using a second camera for capturing the screen at POT size has doubled the drawcalls! I am currently working on trying to use only one camera for the POT image, EVEN if it means disabling the main camera to do it!

 

For all to hear as well: basically, don't try and use my source code as if it was your own, and it will be fine. You are free to use it for anything else, especially for commercial use: what's the use of a free indie fx pack when you can't use it in a commercial game?!

BTW, Eric, thanks for making that logo! it's epic! may integrate it later!

 

Sooo.. this means we can use the effects for commercial use as well?? @FuzzyQuills

 

Yes pretty much but some shaders MAY have copyright restrictions...

 

Thanks man!!!!

 

Wait! So I can post more effects?!

 

I will only use the motion blur.. Does it have copyright restrictions?? @Eric2241 @FuzzyQuills

 

I don't think so.

 

yes you can however since you port a lot of willywills effects he may have some copy right restrictions to some of the shaders. and you'll have to ask him for permission to port those shaders he made.

 

Here are some more of the Unity image effects, I have one more but I'll just have to find it in my files.

Attached are the Sepia Tone effect and the Noise effect.

 

Here is the updated hdr shader; it keeps telling me that it "Temporary register limit of 16 exceeded; 17 registers needed to compile program" .

Who should i ask for permission to use the motion blur because i need it so bad for my project and i couldnt find it anywhere else.. Btw thanks everyone for the answeres. D @Frostbite23 @Eric2241 @FuzzyQuills

 

I believe its fine. Can I see a link to your project?

 

Sure.. I will send a link to you in the conversations as soon as im done with the demo where im gonna use it.. @Eric2241

 

@Eric2241 add this

Code (JavaScript):

1. #pragma target 3.0

this will target shader models 3.0 and higher and this allows more registers to be used however lower shader models have lower registers (i think I'm using the wrong name).

 

Cool thanks, I'll try it out tomorrow!

 

Thanks everyone! Frosty, I want you to pack your current fx into one big pack, then send a link to me. (A Dropbox link, perhaps? )

Eric, you have already done this by the look of it, so thanks for your cooperation! and I realised why my blurring for the bloom effect was so expensive: I was blurring the image per texel, instead of the whole image, which didn't look terribly good either...

and also watch for copyright restrictions, if you need to, ask for permission before porting! I don't want to get mixed up in legal problems...

@XrOs_FiRE: Yes, the motion blur has no restrictions whatsoever, I even encourage you to improve it if you like! (and have the knowledge!) And what's this project you speak of? I am considering an image gallery for IndieEffects as this thread only really has images of my *terrible* test scene.

 

WTF!!!! it just inverts the color!!!

I'll compile all my fX into one big pack tomorrow. As at the moment the are just kinda loose files but if you have the time or want to just download all the effects and make an archive of them.

 

Erm... your screenshot is saying "NullReferenceException," could that be the problem?

And yes, where possible, grab all the files and pop them into one pack.

and your dist variable could be the problem. try adding instead of subtracting.

 

I don't think so, because it's most likely pointing to something I forgot to assign in another script, though changing the values does nothing at all. I'll try your suggestion. This should be the shaders and scripts.

 

@Eric2241 the pragma 3.0 doesn't change anything in the shader, it just only allow shader models 3.0 and higher so more registers can be used.

 

I realized that after taking a look I'm the documentation, though the shader is from sweetfx and its hlsl so the "meat" portions should work. It does I took a look at this http://delightlylinux.wordpress.com/2014/02/04/sweetfx-hdr/ though that means that the values aren't working.

 

The links are down, can you reupload it?I'm not being able to download it.

PS: I highly recommend Mediafire. Thanks!

 

Which one?

 

Here is the current HDR effect; problems include the values not doing anything though the C# script should be correct.

No nevermind, it was Google Docs extension that wasn't letting me download (don't know why)
Sorry for any trouble.

 

It's fine, happy developing!

 

That doesn't look like HDR to me, it just looks like some bloom with values customizing the image.

 

It's not true hdr but it's better than nothing. Could someone help me fix the script; right now the values won't change.

 

whenever I even touch the shader, it crashes unity. Also it makes the screen go black whenever applied. Is the script and shader complete or is it not finished?

 

The hdr power amount is too high make the radius2 value 0.5 less than the hdrpower amount.

HDR like effect

Here is the effect, I'm still getting it to work more properly.

Hats off to Willywill for helping me to get this to work.

Screenshot:

Maybe a web demo could win us over? i don't see anything either...

A youtube or vimeo clip would be nice too, if uploading a player is too much for your internet. BTW, if you need some help, I can ask Cyrien for pointers, as he got a form of HDR working with his pack.

 

This is the sweetfx shader ported to unity so it's not ture hdr, but if you could ask cryien for some help for a true hdr shader that would be nice! However as for the player unity won't compile and build anything from my current project...
