SkeletonLit Shader Question

Tannon

Using Spine's SkeletonLit shader, I see strange light behavior on the edges of the radius of a point light. How can I make it light more consistently across the surface as if it was continuous?

As seen in this example: https://dl.dropboxusercontent.com/u/153 ... xport.html

Is this an issue with the SkeletonLit shader?

Using spine-unity, not tk2d.

This is an issue with vertex lighting in general.
But I've used SkeletonLit with Unity's lights and I've never seen this weird flickering before, though it is what I originally expected. It's always looked more acceptable than I expected since the light contribution to vertex lights gradually disappear. I've never seen it drop around the edges so abruptly like this.

I'm just shooting in the dark here.
Try to always put the light in front of the skeleton, not behind.
Also try to open SkeletonComponent.cs and edit the line that initializes zSpacing. Make sure it sets it to 0.
Other than that, I can only imagine it's some sort of thing with the light settings.
Maybe with the scale? Unity sometimes causes problems when you use 1:1 pixel to world unit scale.

Vertex lighting only works well when the distance between vertices is quite a bit smaller than the light. However, this doesn't seem to be your issue. Pharan's suggestions sound good.

I tried moving the light in Z, and no matter the distance from the puppet I still get the sudden darkening on the edges of the point light's effectiveness.

I also tried adjusting the scale of the puppet and the light both up and down and it also does not seem to affect it.

I edited SkeletonComponent.cs and as far as I can tell zSpacing is initializing at zero.

Is there an alternate shader or lighting type I should try for better results?

Apologies, I'm much more of an artist and some of intricacies of these technicals elude me.

Edit: Oh dear. I found the solution and it's stupidly simple. I had the intensity of the light at 8, rather than increasing the range. Once I set the intensity back to one the problem goes away. Sorry.

Pharan

Cool. I'm glad you fixed it.
I guess a really high light intensity makes the falloff of the light effect more abrupt instead of gradual. I didn't know that.

Thanks for the info!
Sorry I misled you with my suggestions. :x

Tannon

Yeah, that's exactly it.

Thanks very much for the help.
