Understandable Mitch. Thanks for at least replying.

I'm trying to figure out how to update the SPINE shader to at least receive shadows in Unity.

For anyone that's following this thread still. There is another topic ongoing about lighting\shadows

much thanks!

This project is simply too good to get lost in development!

Everything about it is amazing and unique.

I don't believe you will ever find any other instances of 2d dynamic lighting and specularity working together so perfectly the way they do in this demonstration here.

The fact that you were able to create shaders that deliver highly complex lighting, but still manage to preserve a very smooth cartoonish/2d graphic style should be considered a great accomplishment that is worth completing for the runtime no matter how difficult the obstacles.

There are many of us who wouldn't mind if you even released a fraction of the features you described. Many of us just simply wish we could get our hands on that amazing demo file to experiment and play around with.

@Mitch, I believe it's worth considering (at the very least) to release a small demo file for the community - esp. if it is simply too difficult to complete the full project at the moment (considering that you may be preoccupied with more important matters).

Note that forum user ToddRivers has released a Spine-Unity-compatible Sprite shader pack : Sprite Shaders for Unity

The samples don't show the light ramp feature (For stepped-tone shading) but it's there.

Amazing stuff!!! it really looks very good, I'm really excited to know when this is going to come out!. THANKS Mitch!

Status? We really need this.

Please see this thread for a continuation of shader discussion for Unity. I'm locking this thread for now, Mitch can unlock it if he is ever exhumed.
