The cloud mesh radius came from the render distance, the far plane was capped at max(4 x render distance, 1024) and the cloud fog end was a constant 2048, so lowering the render distance cut the clouds short. Vanilla ties all three to options.cloudRange: CloudRenderer.prepare builds ceil(range * 16 / 12) cells, Camera.depthFar is max(4 x render distance, range * 16) (also the hand projection, the frustum and the world border), and AtmosphericFogEnvironment ends cloud fog at min(range * 16, visual/cloud_fog_end_distance). The cloud render harness now checks the radius for Cloud Distance 2..128 against the shipped mesh builder, and the environment harness covers visual/cloud_fog_end_distance.
