Hi, I've been building a scene and I would like to make some of the
GLMeshItems tranlucent. I have set the alpha values in the colour array to
0.5, but they draw solid.
I have also tried to enable alpha mixing via
... = gl.GLViewWidget()
glBlendFunc(GL_ONE_MINUS_SRC_ALPHA, GL_SRC_ALPHA)
glEnable(GL_BLEND)
glEnable(GL_COLOR_MATERIAL)
but this gives a GL error message:
OpenGL.error.GLError: GLError(
err = 1282,
description = b'invalid operation',
baseOperation = glBlendFunc,
cArguments = (GL_ONE_MINUS_SRC_ALPHA, GL_SRC_ALPHA)
)
Any idea about how to get this working?
Thanks,
Lucas
