[ccp] Custom Shader

fallen

Is it possible to use a custom shader for some of the regions within a spine and not for others?

I'm on a pretty old version of the runtime, Cocos 2DX spine runtime 2.3. I don't think tint is supported so I am not sure the runtime is using a shader at all. Maybe I'm wrong about that.

Is it possible to do? If so, perhaps can someone point me to the current runtime where the tint shader is setup and I can try to back port it for my own purposes?

It should be possible, but the SkeletonRenderer class doesn't support it out of the box.

Our current cocos2d-x runtime implements batching itself via SkeletonBatch and SkeletonTwoColorBatch. See spine-runtimes/SkeletonRenderer.cpp at 3.7

The SkeletonTwoColorBatch uses a custom shader and does its rendering through OpenGL directly. You can see this here: spine-runtimes/SkeletonTwoColorBatch.cpp at 3.7

Note that you will break batching, and thus decrease performance, when switching shaders between slots/attachments of the same skeleton.
