Icarus Week 236 Update Adds Ubis Breeding and Phenotypes

Week 236 introduces breedable swamp birds with multiple phenotype variations, alongside aquarium optimizations and prep for upcoming trader changes.

Ranching options expand in Week 236 with the introduction of breedable Ubis. Prospectors can establish breeding populations of these swampland creatures to discover and collect up to seven distinct phenotype variations using custom serums crafted at the Ranching Station.

Ubis Husbandry

Players can breed Ubis by utilizing the newly added Ubis Serum crafted at the Ranching Station. The system supports discovering and collecting seven distinct phenotype variations among the swamp birds.

Aquarium Quality of Life

Aquariums receive a user experience pass that resolves client desynchronization issues. Optimization improvements include distance culling for fish skeletal meshes and corrected material setups across aquarium variants.

Collision and Map Fixes

Expensive or unnecessary collision setups on numerous meshes are optimized or removed. Lake depths in Outpost 006 are adjusted to force sublevel regeneration and fix invisible water inside caves.

Why this patch matters

Week 236 enriches basebuilding and ranching loops with dedicated breeding mechanics while clearing out lingering visual and collision bugs.
