[Unity] SkeletonUI incorrect colors

ophilbert

Hi everyone,

I'm having an issue with Spine on Unity and I don't know what causes that (an export option maybe)?
Using SkeletonAnimation in my scene is fine but using SkeletonUI gives a weird additive color.
I attached a screenshot of my problem:

in the background is the SkeletonAnimation of my character
in the foreground is the SkeletonUI of my character, as you can see the face has a weird white color that shouldn't be there

I also added one of the example files as UnityUI and it looks fine, this is why I'm suspecting an export option or something like that.

I tried updating the runtime but it changes nothing.
Your help is always appreciated, thanks.

Can you share your project with us? You can send it to unity@esotericsoftware.com

That's also an awfully specific shape over her face. Is there anything that has that shape in Spine editor when the skeleton was made?

The email was sent with all the required details. I will update this post once the cause of this has been found.

Thanks! I found the problem and applied the fix to the runtime.

It was pretty simple to fix so you can apply the changes yourself immediately.
Check the changes here: [unity] Fix SkeletonGraphic not applying PMA to vertex colors. · EsotericSoftware/spine-runtimes@c9ffdc7 · GitHub
Search for and open ISimpleMeshGenerator.cs and SkeletonGraphic.cs in your project and add the two new lines of code indicated in the link.

These changes will be included in the next .unitypackage update next week.

On a separate note, why do you have that fully-transparent image over her face? Did you actually mean to hide that image instead?

Thanks for the quick answer and for the fix, it works like a charm now.

Regarding the animation, we could just hide it on this character and on this particular animation. But it is meant to be progressively animated from alpha 0 to 255 on transitions such as when the head turns. We'll see that kind of animation all the time and if then the part stays additive, the problem remains the same.
