Hello
I searched on the forum but i didn't find exactly what I was looking for,so sorry fi its a repost, is there a way to have a gradient from a colour to full transparency on top of a spine character in unity? So the gradient will always be from bottom to top, but won't affect the animations, or the background?
thanks
You could write your own shader (based on one of the shaders provided in the spine-unity runtime) that adds such a gradient overlay effect at the end of the fragment shader. This would then render in a single pass and save resources.
If you for whatever reason need to keep the overlay separate: Alternatively you could write a (or use an existing) gradient shader that renders the existing skeleton mesh again. You could use the RenderExistingMesh component to re-render the same skeleton with a different Material and shader. This however comes with the drawback of multiple semi-transparent pixels of overlapping attachments being overlaid multiple times, so here we would recommend having z-write and z-test enabled to avoid such multiple overlays. For these reasons we would recommend the first solution over this one, unless you don't care about overlapping attachments.
