Having Particle Core installed causes some particle effects from Particle Rain mod to not look correctly.

• The ground fog particle will very noticably disappear and reappear as you walk around. This is most likely due to a particle culling optimization.

In my mind the best way to fix this would be to provide an API via which mods can exclude specific particles from culling.

Demonstration:

• No Particle Core (correct result)

• With Particle Core (incorrect result)

I agree with Leclowndu93150 that a whitelist would be needed for Particle Core, something I can look into added for the next update.

@PigCart I don't think there's anything you could do at the moment to fix it from your end. I chose to make particle core both slightly more aggressive and more CPU-efficient with culling by simply checking the midpoint of the particle rather than each corner of the box.

Beyond or in place of a whitelist I might include some option for changing this culling behavior to use the full box, maybe by particle type, maybe just a general switch in case problems are noted. A whitelist would impart some performance impact that I'm not particularly fond of.

ive increased the fog bounding box to match its quad size, but particle core doesnt seem to use the bounding box (subtle effects does for its culling). let me know if theres anything i should be doing differently on my end :]
