ToddRivers ：

...If in your game you rotate your sprites 180 degrees around Y to make sprites face the opposite way, you should also tick 'Allow Back Rendering' in order for lighting to work correctly when Sprites are facing away from the camera.
If you use negative scale or 'FlipX' instead then leave it unticked and it will save a little bit of processing time ...

Where is this Allow Back Rendering? It is a Unity or Shader feature?

Hey guys, this was happening when i imported this shader.
We are using Unity 5.3.4f1 (64-bit).
Also there is any restriction for this shader to work on PS4/XboxOne?
Thanks =)

Honestly, if you're on PC, and are aiming to create a scrolling beat'em'up or platform, I suppose you're going to have about 5-30 Spine entities on screen.

Even on old hardware, per pixel lighting shouldn't affect performance too much, I'd honestly stick with that and find a way to make them work (try both the ToddRiver's and the Spine version of the pixel lit shader, I'm experiencing totally different behaviours).

If you really have to fall back to vertex lit, you could still use a low-med grid, but positioning the rows and columns in a way that they form a bevel around the shape, and also by making the lines follow both the texture details and the general 3D shape of the character. A plain grid gives a suboptimal result in my opinion. You may even fake some sort of bump mapping or rim lighting by positioning the vertexes appropriately.

I suggest to stop and take some time to think about this decision, since changing everything in the middle of the project could simply make you want to trash everything and start over. Or, at least, many would be prone to do that.

Just giving my opinion/conclusion if anyone stumbles upon the same question:

Pharan confirmed what I was suspecting... Thank you!

NeatWolf, that's an excellent idea! I tried the the bevel shape, it looks awesome enough and it performs great! I dropped 30 enemies which used 30 vertices each. It should come out fine, considering I'm probably only going to have 5-10 enemies at once. Everything else, not character related, is going to use something else.. like PixelLit.

ToddRivers ：

the latest shaders only support Unity 5.6 unfortunately. I don't have time to backwards support old version of Unity

Ouch :-/
Are the official shaders still at least 3 months back compatible?

This would be a bit awkward, also because since Unity acquired Anima2D which is available for free and also starting to be integrated and improved natively, not even having some support for shaders is definitely not going to be of help for a 3rd party product with not-so-cheap subscriptions required by multiple users in the same team :-/

Hey there!

I've tried using your shaders, specifically for the Overlay color aspect of them! That does exactly what I needed it to.

There is a problem, though. I have multiple instances of enemy characters. They all use the same SkeletonDataAsset, the same AtlasAsset, and therefore the same Materials. Therefore when I make just one of them flash red when taking damage, it makes all enemies of that type - enemies that use the same material - flash red, too.

I thought at first that I could make instances of the materials, but then it would break the AtlasAssets, as they are ScriptableObjects. I could instantiate the AtlasAssets, too, but they break the SkeletonDataAssets, because they're ScriptableObjects, too. I mean, I tried it, but with all that going on something broke completely. And I'm not a fan of creating whole new instances of things anyway as that will take up lots of memory.

Is this something you could provide some guidance with? Although perhaps this is more an architectural issue with Spine. I know before that the tinting via the "SetColor()" method was done by modifying the vertices of the mesh (I think).

Thanks very much!

I think you want MaterialPropertyBlocks.
We have a small writeup about it here: https://github.com/pharan/spine-unity-docs/blob/master/Rendering.md#setting-material-properties-per-instance
Sorry for the lack of images, but there's sample code.
Essentially, setting a specific Renderer's property block overrides the Material asset's property values with its own, which allows you to set values per renderer instance.

I've put up screenshots of the list of property IDs, which you can see yourself by selecting the Shader in your inspector.
https://github.com/traggett/UnitySpriteShaders/issues/9#issuecomment-303629612

For example, to set a MaterialPropertyBlock's Overlay ("OverlayColor") property, you'd go:

MaterialPropertyBlock mpb = new MaterialPropertyBlock();
mpb.SetColor("_OverlayColor", Color.red);
GetComponent<MeshRenderer>().SetPropertyBlock(mpb);

This has been the preferred way to set material properties per Renderer in Unity for a while.

You may have seen modifying the returns of renderer.material or renderer.sharedMaterial as the method in very old Unity code but that has historically resulted in too many bad sideeffects.)

This is also probably the wrong thread. I'll move this to a new topic after you reply.

Don't know if anyone realizes this, but this is probably the most popular thread on Spine's Unity forum. Almost reaching 24,000 views at this point. It's even more read than Pharan's official post http://esotericsoftware.com/forum/Noteworthy-Spine-Unity-Topics-5924

It'd be nice if the Spine guys could pick up the torch and continue to iterate \ support Sprite Shaders or just contract out the support work (both legacy and current Unity versions) to ToddRivers?

His shader makes a significant impact to the visual quality of Spine's animations and helps keep it on par with Unity's Standard Shader. (Without it maybe Anima2D has a leg up?)

ToddRivers, your contribution to Spine's visuals is a huge one, hopefully you get the recognition you deserve. :rock:

With so many lurkers in this thread, it's a shame only a select few bother to get involved in the conversation. If you guys are using this tool and appreciate it, say something..

That being said, I'm more or less following alongside ToddRivers, I'm updated to 5.6 and the shaders are working beautifully. ToddRivers should we update to 5.6.1 now? :party: Haha

You have to admit the topic and content of the first post is pretty SEO optimized.
It literally says "Sprite Shaders for Unity". Imagine how many people google that.
I just googled it and it's the 4th result.
Which is apt, because it's actually not Spine-specific. He actually uses it for more than just his Spine stuff.

I don't call the shots regarding who contracts who. But absolutely, anyone who uses this should credit him with big bold text in their game. It should be the first logo when the game first boots up. 'cause he shares his Sprite shaders to the world freely.

The current spine-unity 3.5 unitypackage is actually packaged for Unity 5.4 and includes the shaders in a 5.4 compatible state, though it probably doesn't handle some of the gotchas like platform-specific depth or normal direction weirdness, if any of that exists.

How to get sharp shadow edges ( toon shading ) like in this video?

SOLVED:
Create a new texture with any resolution (power of two preferably), and paint the left half of the texture with a dark color, and the right half with white. Then place the texture in the Spine/Sprite/VertexLit material's Diffuse Ramp texture slot in Unity.

Yes, that's what Diffuse Ramp is for.

Thanks for sharing.

Is there any way to fix the problem that the light doesn't come from the same direction all the time?
It's as if the light moves with the object as the object rotates, and half way through the rotation the light flips to the other side. It looks really weird.

Is this a bug with the shader?

EDIT: Solved after many hours frustrating hours. Solve Tangents must be enabled under "Advanced" in SkeletonAnimation.cs.

Hi @Pharan,
It would be interesting to see if the majority of the lurkers on this thread are also Spine owners or just guys that googled it looking for a Sprite Shader.

It's a complicated topic on this shader. Good mention on the credit bit, for sure we should all be crediting ToddRivers in the game if we're using it.

I noticed that after updating Unity the emission channel doesn't produce HDR effects, even if the Emission Power is set to very high values. To fix this I cannibalized the Standard Shader and its implementation of emission channel:

on line 704 of SpriteShaderGUI.cs - replaced this

_materialEditor.TexturePropertyWithHDRColor(_emissionText, _emissionMap, _emissionColor, new ColorPickerHDRConfig(0, 1, 0.01010101f, 3), true); 

with this

_materialEditor.TexturePropertyWithHDRColor(_emissionText, _emissionMap, _emissionColor, new ColorPickerHDRConfig(0f, 99f, 1 / 99f, 3f), true);

Awesome credit! 8)

Btw congrats on the game release, I saw it on the new release list. Didn't know that was your game :party: ):

Hmm would it be possible to expose this into the Inspector for easier use?

new ColorPickerHDRConfig(0, 1, 0.01010101f, 3)

Some real quality shaders, thanks for all the hard work ToddRivers!
