Snow_storm I don't understand this concept 😢 maybe like this: glBlendFunc( GL_ONE , GL_ONE); it's right? :think:
Nate If using premultiplied alpha images, use GL_ONE, GL_ONE for additive. If not using premultiplied alpha images, use GL_SRC_ALPHA, GL_ONE. You can Google about additive blending with OpenGL, it isn't Spine specific.
