► Subsurface Scattering Shader ◄

Hi Arkhivrag,

I recently bought Curved World and Subsurface Scattering Shader assets. I'm trying to get the VertexLit (Mobile) shader working, but I'm getting a bunch of errors when I try and apply it.



Is there something I haven't configured properly?

Cheers,

Owen

 

Seams shader is not compiled at your side and editor can not handle 'uncompiled' shader's variables.
What's Unity version?
What's OS?
Can you try importing Curved World and SSS assets in new(fresh) project.
Also, in material editor for 'problematic shader' click gear icon and choose Select Shader, that will display inspector for shader and it will contain more why it is not compiled on your device.

I'm using Unity 5.1.3f1 Personal on a MacBook Pro - OS X Yosemite.
The above was from a new project with only Curved World and SSS assets imported.

I did some hacking and I think I've found the issue. I'll send you a direct message with the details.

 

Fixed in update v3.11

Hi

I have a question - Does translucent works on object density as well, like if same object has different density on different areas then light should pass from less denser area and should not pass from high density areas.

Does your SSS work for this as well?

 

Mesh density is not taking into account. Otherwise shader will not be so fast as it is now. But you can darker translucency map for imitating depth.

Hi,

I just upgraded to Unity 5.3 and the Curved World particle shaders don't seem to be applying the curve anymore. I realise Unity 5.3 has only just been released, but would you be able to have a look into this issue?

Thanks

 

Use Curved World support forum: http://forum.unity3d.com/threads/curved-world-2.344041/

It seems this issue is specifically with SSS curved world shaders, not an issue with the curved world asset itself. I unchecked the "Use With Particle System" option, and the particle effect is then displayed correctly with the curved world settings.. which seems a little backwards now.

 

Hi Arkhivrag,

We are using your amazing shader for the subsurface scattering but we are finding the following problem:

When 2 different submeshes from the same 3D Model use the shader we are seeing the line between the two submeshes. As you can see in the image called "WithLine.jpg".

Can you please help us with this? May be is a shader configuration problem or shader problem...

Thank you very much and kind regards

Ibai

 

In attached image I do not see any shader problems. If you mean 'line' at neck it's because of two submeshes have different normals and blending is not smooth.

Hi again,

thanks for the quick reply,

yes we mean that line at the neck. I will double check with the art team but I am pretty sure they averaged the normals of the two submeshes.

I will also do a script to show the normals on the neck in diferent colors to double check it

Thanks and kind regards

Ibai

 

Hi there! - I really like your shader, but it uses a frustratingly high number of shader keywords, and I can't remove the one I don't need, since they're mentioned in the DLL file. Could you somehow expose the shader keywords to the user?

Thanks

 

Only 3 pairs of keyword:
1. V_SSS_NORMALIZE_DIFFUSE_COEF_OFF V_SSS_NORMALIZE_DIFFUSE_COEF_ON
2. V_SSS_ADVANCED_TRANSLUSENCY_OFF V_SSS_ADVANCED_TRANSLUSENCY_ON
3. V_SSS_RIM_OFF V_SSS_RIM_ON

And you can remove them from shader file.
Or if are using just replace (eg. rim effect)
#pragma shader_feature V_SSS_RIM_OFF V_SSS_RIM_ON
replace with
#define V_SSS_RIM_ON

Huh. I tried that, but there must be some material that I haven't removed the keyword reference from. - Sorry for asking before researching it properly, and thanks for the fast reply

 

Awesome asset. Have one question though. Is there a way to make the shader slightly transparent? I need to place a small sphere inside my object that can be seen through the surface.

Thanks

 

There are no transparent shaders int he pack, but you can modify them. All you need add transparency tag and blending mode.

How does this shader do on performance of a large quantity of clones?

 

Wow, these look extremely high quality. Very photorealistic.
I'm impressed.

 

If you are asking about Unity 5.4 GPU Instancing feature - it is not implemented yet.

Shaders in this asset look very nice. Thank you Davit
If you will have spare time, would you please consider adding transparency?
I am sure this feature will help many.
You've mentioned that it's possible to add tag and blending, but I have no idea how to do that
Anyways , thank you
great asset

 

Added to wishlist.

Hello, I'm very interested in purchasing this shader for my project, but before doing so, I have a question: does it work with deferred lighting? Reading the comments section in the Asset Store, I can understand that when rendering in deferred, objects with SSS cannot receive shadows, which is not such a big deal for me (although I'd prefer the opposite). But, besides this particular limitation, does the shader work?
Thank you.

 

SSS effect is rendered in Forward pass. Yes it works with deferred lighting.



VacuumShaders - Facebook Twitter YouTube

 

Thanks for the answer. I already bought it and I'm doing some tests right now. It's looking great so far

 

I can report that it's working on several hundred instantiated objects all moving with physics without a hicup. nice work

 

Hi,
I am trying to recreate the effect of stained glass window, like in this image:


Is your SSS shader capable of doing these effects?
1) mapped translucency
2) mapped transparency, so it's see through
3) normal mapping
4) participate in GI.
5) cast coloured shadows (or at least the grayscale shadows, like the Standard shader)


I need this effect with a dynamic GI, to see how the sun passes through the window at different times of the day.

 

Hi there, I'd love to see this shader in action on a human face model before I buy... do you have any examples of that? thanks

 

1) yes
2) no
3) yes
4) receives GI, but does not emit it.
5) no

I have not designed SSS shader to be used as a skin shader, if it's what you are looking for.



VacuumShaders - Facebook Twitter YouTube

 

Thanks for the answer.
Regarding the coloured shadows and GI - I think I would be able to fake these with reasonable results (fingers crossed!)
But do you have any plans of adding transparency support to your shader? I read in an earlier post, that you had added it to the wishlist...
If you consider doing that, please make sure to have the refraction affected by the normal map... Thanks!

Oh, and not sure if I asked about that:
6) reflections - are they supported?

 

Yes, standard cubemap reflection.

Thanks for the answers.
Right now however transparency is crucial for what I need. I'll be watching your shaders for any upadates in the future.

 

Hi!

Does your shader supports double side planes with cutout? I would love to use it for foliage on trees

 

All cutout shaders inside package are double sided.

Is that working in VR or not?

 

Works.

I have purchased your shared it is good and working well but there is no Occlusion properties for contact shadow. And I am using these shader's for Mobile VR(for organic look, like human body internal parts). Can you give me suggestion for organic look in mobile VR.

 

You can enable Advanced Translucency option and use Translucency Map for limiting lighting areas.
All shadows are rendered by Unity, that does not 'see' translucent shaders.

It is giving error while I import it in unity VR project.

Denoted error by unity while compilation is given in the attachment.

Kindly Suggest appropriate solution.

 

And how that error relates to the SSS shader?

Just installed into a fresh Unity 5.3.7f1 file and I'm getting this error on the ambient VertexLit versions

undeclared identifier 'unity_ObjectToWorld'

SSS.cginc:442

Sorry, forgot to update description.

That said, is it something that I could edit myself to make it work in 5.3, is it just that one function or does it run much deeper than that

 

Try changing all unity_ObjectToWorld variables inside shader to _Object2World.

Hi @Arkhivrag!

I'm considering buying this shader for a VR project. Does it support the single-pass stereo rendering method?
