Screen Space Fluids Shaders [RELEASED]

Is there any way that this could work with webgl or mobile apps?

 

@dansav SSF shaders probably yes, but uFlex is using CUDA and, as far as I know, there is no WebGL plugin or mobile device (except maybe NVidia Jetson) supporting CUDA. However, latest Flex 1.1 was ported to DirectCompute so in theory it should be also possible to reimplement it for webgl compute shaders.

 

Is it possible to use SSF shaders with unity particles and output as WebGL?

 

Yes, you can use it with standard particles. The SSF shaders are quite complex, but in theory it should work.

 

Hi Korzen,

I've tried contacting you via the support email in the asset store page. When an object in moved in front of the SSF, the fluid is drawn on top of it regardless of its actual position. How do I resolve this?

 

@papathor, which Unity version are you using? This should be fixed for 5.5. Are you using the latest SSF/SSF Pro version (0.11 and 0.31 respectively)

 

I'm using 5.6.1 and the latest SSF Pro, the problem is still persisting.

 

Actually when did you last update it? I haven't reinstalled SSF since I sent you the first (of two) emails about this problem.

 

I have a similar problem as papathor

Here are some pics illustrating the problem in my project:



When I place the white evaporating dish (uses just a Unity standard shader) in front of the glass beaker containing some SSFPro liquid, the liquid (only) is not hidden by the dish, but shows through it.....as follows:



And when I pour some of the liquid from the beaker into the dish, the liquid is visible through the sides of the opaque dish.....as follows:



The same applies to the funnel...when liquid is poured into it, the liquid is visible through the funnel sides.

Seems to be some kind of particle sorting problem?
The liquid consists of standard Unity particles with SSFPro shaders applied

 

Using uflex+ ssf Pro...
Is it possible to do a variety of fluids in a single scene?

Example:

Water + bloodLiquid
Sewage + clean water
redLiquid + greenLiquid
....

 

Please could I have a response on my problem above.
Is there a possibility of a quick fix?
A bit of a bummer if not.....I'll have to turn all my opaque objects into transparent glass !

 

I can only assume that the lack of comment from the developer 'korzen303' implies that that he has no solution.
This means that I also cannot use uFlex (which I also purchased from the same developer ), since I was hoping to apply the SSFPro shaders to the uFlex liquids in my project.

This example adds to my reluctance to purchase from the Asset Store.....once you've made a purchase you cannot always be sure of the developer's timely support.

 

The same problem.
Fluids are completely visible through a transparent object with any alpha.
Although logically the transparent object should darken the fluids depending on the alpha value.
ps:unity 5.5.4 ad 5.6.3

@jugadorgl Awesone! Congratulations

 

to @korzen303
Thanks.
Could you fix the bug with full visibility of the liquid through the materials with the alpha channel?
It is necessary that the visibility decreases with the decrease in the transparency of the material.

 

@korzen303 I am curious if you have done any performance bench marks between screen space fluids and obi fluid. I plan on working for VR so I am trying to pick the most optimized solution.

Edit: Would also like to know if multiple fluids in a single scene are supported, as there is a review on the store page that says only one is.

 

Obi-Flüssigkeit is Only CPU Maximale kompatibilität ( Particel 3000 > FPS 50) 8x Core Obi have less error

GPU is better uflex and Screen Fluid ( Particel 6000 > FPS 60) 8x Core - more error code Build Freez

 

Hab ich auch denn Fehler--

 

Firstly, I'm so glad I found this along with Uflex; it's quite difficult to actually get work done sometimes when I'm having so much fun playing around with the liquid simulation.

Anyhow speaking of work, I'm trying to implement this into a VR solution and while uflex and the shader function quite well in with the Oculus I'm running into a bit of an issue. When I tie the SSF script into the camera of the Oculus rig I get a split vision instead of the uniform vision you normally get (shown below).



Not sure if this is the right place to be asking the question, but it seems applicable. In any case, I figured I'd post something here to see if anyone else has any ideas while I tinker and try to solve my own problems.

cheers!

 

@RelSavo Please try setting Stereo Rendering Method in Player/XR Settings to MultiPass

 

Thank you so much korzen303 that totally worked!

 

@korzen303 Can you migrate the "SSF_Pro_v0.31 uFlex_v0.55 Integration" package to use the Post Processing Stack (preferably v2)? ImageEffects were deprecated at some point, with the recommendation to use PostProcessingStack instead.

 

Couldn't find any publishers email or contact details on the asset page so posting here:

Is this asset compatible with Desktop VR or is it too demanding?

 

The system works pretty good. The only problem I'm having is with multiple particle systems in the scene. It only ever seems to draw the last system that was initialized. Is there any way to have multiple systems running at the same time? For instance I have enemies that vomit acid but it only ever draws the last entity that walked in.

I'm not above modifying the system myself if you can point me in the proper direction.

It'd also be nice to use more than one fluid type in a scene (like to use it for both acid and blood) but with the color properties and stuff on a single class on the camera it doesn't seem like it supports that yet. Any ideas would be helpful.

The asset has a lot of potential.

 

Sadly it looks like the dev is not longer "nearby". Still, I think i will be able to implement the color-per-particle thing

 

Hi Petersvp. I saw in your review on this shader you were able to make it work with multiple particle systems. Would you be willing to share your version of the code with me?

 

I'd like to recommend my water shader asset which is more handy and powerful.
