We want to use a Spine project including some layer of Multiply blending mode in Unity. I found this: http://esotericsoftware.com/forum/Multiply-Blending-not-exporting-as-it-should-7991. We are using spine 3.6 so it's quite easy, if I choose to use SkeletonAnimation.
However, we need to integrate it with the Unity UI system, so I have to use SkeletonGraphic. I cannot find any information about using Multiply blending with SkeletonGraphic, and SlotBlendModes doesn't work here.
My actual case is in fact more complicated. We have too much large slots that I'm using SkeletonGraphicMultiObject (downloaded from http://esotericsoftware.com/spine-unity-download) to support multiple textures, rather than SkeletonGraphic. I've read related code and tried to modify calling to MeshGenerator.GenerateSkeletonRendererInstruction in SkeletonGraphicMultiObject.cs but no luck.
Any suggestion will be much appreciated.
