LibGDX transparency issue

DKoding

Hi.

I have some trouble with transparency of the skeletons imported from Spine to LibGDX.

I have tried a lot of combinations like this:

color.set(1f, 1f, 1f, .5f);
skeleton.setColor(color);
spriteBatch.setColor(Color.rgba8888(1f, 1f, 1f, .5f)); // Spritebatch color is ignored completely it seems
renderer.setPremultipliedAlpha(false); // Also tried true
renderer.draw(spriteBatch, skeleton);

The closest I got was getting each element transparent, but then the items I drew were all transparent so I could see the body though the arms and the legs through the body etc. Not what I want. I want the whole image to render, then that image to be rendered transparent. I guess the solution is in setting the correct GL blend mode?

Any help on this?

Also why does the renderer ignore the color I set for the spritebatch?

Regards

This is always how it will work unless you do something special. This is how all the other runtimes work.
Your solution may require you to render this skeleton to a temporary FBO first, then draw than FBO with a lowered alpha blend. I'm not sure about the details (how this would work in low-level OpenGL/libGDX)
