Particle Core

What it does Particle Core targets the particle system. Vanilla spawns and renders particles even when they sit outside your view. This mod stops that waste with frustum culling - only the roughly one-twelfth of the particle lightbox that falls inside your field of view gets rendered. The remaining particles never reach the GPU. For particles that do render, vertex transformations and lightmap lookups are optimized. When Sodium is present, Particle Core defers vertex work to it instead of duplicating effort. ## Spawn control You can reduce or disable specific particle types three ways: - Add particle identifiers to the particle_core:excluded_particles tag to block them entirely. Server owners should note this tag affects every client that joins. - Use the config map reduceParticlesByType to assign a spawn chance between 0.0 and 1.0 per particle type. - Toggle turnOffPotionParticles to remove potion swirls completely. Unlike resource packs that only hide particles visually, these methods prevent the particles from spawning at all, saving CPU time. ## Fine-tuning vanilla tiers Vanilla offers three global settings: ALL, DECREASED, and MINIMAL. Particle Core adds two dials that sit between them. reduceParticlesAllChance interpolates between ALL and DECREASED. reduceParticlesDecreasedChance interpolates between DECREASED and MINIMAL. If DECREASED still feels cluttered but MINIMAL is too sparse, you can land somewhere in the middle. ## Config and safety The config file lives at config/particle_core_config_v[x].json and includes a commented header explaining each option. A disableOptimizations list lets you turn off individual features by key if something conflicts or you simply don't want it. ## Compatibility Client-side required. Server-side unsupported.
