Transparency in Unity - Shader Newblett

seraphki

Hello!

Sorry if this has been asked and answered, I didn't find anything.

I was hoping to be able to take aa spine character in unity and set its alpha to about 0.5 via a script (only during certain events, which is why I'm not having the transparency baked into the animation) but I noticed when I tried to set color for the sharedmaterial that the shader that _Color isn't a thing for the skeleton shader.

I'm also, unfortunately, woefully uninformed when it comes to shaders.
My spine runtimes are a little old (we version locked a while ago to avoid issues) so if this was implemented already, sorry!

Soooo anyone who can point me in the right direction for adding color to the skeleton shader (if that's something that can be done) I'd greatly appreciate it =]

I don't blame you. The fact that Unity adds an additional couple of shader languages on top of the standard Cg language does not make shaders straightforward to learn.

Here's Spine/Skeleton Tint. (SkeletonTint.shader)

You could also just set GetComponent<SkeletonAnimation>().Skeleton.A. That sets the color.a of the skeleton. Note that the skeleton also has skeleton.SetColor(UnityEngine.Color). The skeleton color is not keyable so there's nothing that would override it except your actual code.
