its a BUG with the 3d starfield plugin & 3d starfield shape, if i use the3d starfield shape with a météor sprite, and in the 3d starfield i add the stars, the only whay to see the meteors on top of the stars is to change the effect to "additive" but then we see the stars trought the meteorites.
its impossible to have the meteors png on top of stars something is wrogn with the transparency with this plugin "3d starfield shape"
here you can see what i mean.
here its the plugin 3dstarfield shape https://s3.postimg.org/slamay2qp/bug01.jpg
here its the 3dstarfield shape in "normal" mode effect https://s1.postimg.org/vdmfls2jh/bug02.jpg
here i added the 3dstarfield shape to "additive" effect, it results with transparent meteorites we see the stars layer "space" trough the meteorites https://s4.postimg.org/3y504s1gr/bug03.jpg
