[FLOODFILL] floodfill flickering / modded blocks
oriononcion opened this issue ยท 5 comments
When FloodFill is enabled, chiseled blocks (Chisels & Bits for fabric) that contain both emissive bits and solid bits in the same block volume flicker wildly and do not emit correct light. Disabling FloodFill removes the effect. Likely interaction between FloodFill voxelization and C&B custom renderer.

In-game: create a block and use Chisels & Bits to place a grid of bits (16x16). Fill some bits with glowstone bits (or other emissive material) and leave other bits as solid (stone/any). Place this chiseled block in world.
With FloodFill enabled, emissive bits should contribute stable, correct blocklight and not flicker. Emissive parts should reach expected intensity and light surroundings consistently.
Emissive part flickers/oscillates, light intensity is reduced or disappears intermittently
- With FloodFill disabled, flicker disappears

Yup this happens for me too! seems to happen in the clouds more often than not
hmm
i would like you to check if the shader is trying to voxelize a normal block or an entity block. this can be tested if you disable entity lights in shader settings -> ambient light -> floodfill. if the light from those blocks completely vanishes it was detecting them as an entity block... meaning it is most likely having trouble detecting the small entity within the 1 block large area, for whatever reason. you can sort of see similar behavior with flaming arrows or mobs on fire/glowing.
if nothing changes when that setting is disabled, then it wasnt detecting it as an entity... which just makes the issue harder to figure out i think :(
this same issue happens with me and i can verify that its a collision with the physics mod
i'm on 1.21.8, iris 1.9.1 and it happens with all versions of bliss i have installed
