URP Skeleton Lit shader tint

pixelmeat

Hi!
I'm using the URP Skeleton Lit shader tint effect for visualizing hits on the enemies in my game.

I have this big boss and I just realised that the tint is creating this gradient effect on the Y axis of the texture using the light and dark colors.

I always assumed that these colors were meant to tint the darker and lighter original colors with different shades between the tint light and dark colors.
Was I always wrong and this Y gradient is the expected behavior of the shader?
Is there any way to achieve a homogeneous tint accross all the texture?

Thanks!

@pixelmeat Please note that the Inspector Preview when selecting the Material in the Project panel is wrong, because it's missing the required additional tint black vertex attributes. The gradient is just a side-effect of the incorrect data the Preview uses.

You can only judge the Material reliably at a SkeletonRenderer. Note that you have to enable Advanced - Tint Black in the SkeletonRenderer Inspector in order to provide the required additional vertex attribute data. This is different from the Spine/Skeleton Tint (Built-In RP, not URP) shader which performs tint black only on the texture-level, and not on the per-attachment data level via additional vertex attribute data.

@Harald I didn't know about the vertex attributes. I shared the Inspector Preview because, in this case, matched perfectly what I was seeing ingame when the Skeleton was being tinted. Enabling the Tint Black option worked perfectly. Thanks a lot for your undying help! You're a true paladin <3

@pixelmeat Glad it helped, and thanks for the kind words! I do my best to stay both lawful and good! 😄

BTW: We've added an automatic check which now lists a warning at the SkeletonRenderer Inspector if this incorrect configuration is detected. Automatic detection previously covered the Built-In RP Tint Black shader, but was missing the material property checks for the URP shaders. So thanks for reporting!
