[Solved] Particle isn't visible from certain angles

[Melonslise]

I've finally got my particle to work like I want it to. However it seems to disappear sometimes when moving around it. Also, interestingly, when changing the blendfunc to ONE_MINUS_SRC_ALPHA I noticed that instead of disappearing the particle turns completely black. Here's an example. Here's the code. Thanks.

I tried compiling my mod and testing it outdev. Lo and behold there are no problems. I guess [SOLVED]

Nvm, still happening.

Fixed with 

OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, 240, 240);

 

Thank you @HenryLoenwind!
