Blood Bits: Flow 2.9.1

This release includes the unreleased 2.9.0 changes plus the fixes below.

Compatibility and upgrading

• The server and every client must run 2.9.1. The network protocol has changed: forge-1.20.1-6 on Forge and 9 on NeoForge.
• Blood is now stored more compactly on items, bodies and blocks. 2.9.1 reads worlds saved by older versions. If a world saved by 2.9.1 is opened in 2.8.3 or older, blood stored in the new format is lost. Back up worlds before upgrading if you may want to downgrade.
• The mod ID bloodbits_flow, namespace bloodmarks, and public API dev.bloodbits.flow.api.BloodBitsApi are unchanged.

Fixes since the 2.9.0 test build

• Item editor: finds and paints textures outside textures/, including the images under assets/mekanism/render/ used by Mekanism's Atomic Disassembler, Flamethrower, Jetpack, Scuba Tank, Scuba Mask and Free Runners. Rules on these textures already applied in game; the editor could not show them.
• Clean skin areas: the model is now drawn at the intended size and aligned with the brush. Previously, it was 16 times smaller and off centre.

New features

Clean skin areas

• Opens on first joining a world and from a button in the pause menu.
• Shows your skin on a 3D model and unfolded flat. Marked texels are excluded from blood, dirt, soot and snow.
• The mask uses skin texels and applies to both vanilla and Epic Fight player models.
• Saved in config/bloodbits_flow/skin_masks/<UUID>.txt; the server synchronizes it with other players.

3D item editor

Open mod settings → Items → Open editor.

• Rotate the item by dragging empty space and zoom with the wheel.
• View the full texture of each part beside the 3D item.
• Paint Block, Allow or Auto pixels on either view with a 1–3 pixel brush; painted pixels are highlighted on the model.
• Captures textures from the item's rendering, including custom renderers such as shields, tridents, chests and many modded 3D items, as well as textures outside textures/.
• "Item in hand" opens the exact held stack, including a shield's banner pattern.
• "Clear item" and "Block item" apply to all captured textures of the item.
• The Items tab shows the item's image and detected textures.

Snow, wetness and rules

• "Delete whole texture" in the Rules tab removes all pixel rules for one texture.
• Snowfall settles on exposed, upward-facing surfaces of players, mobs, armour and held items. Snow sheds outside snowfall and melts into wetness in warmth or fire.
• Held items receive soot while burning and wetness from rain or deep water, then dry.
• Snow and frost also melt on inventory items.

Rendering and gameplay fixes

Epic Fight

• Fixes corrupted textures, disappearing geometry and broken outlines on targeted or glowing mobs.
• Hit placement follows the player's aim, including Epic Fight camera aiming and delayed animation hits. The server retains the last aim point for each of the last four mobs.
• NeoForge: corrects held-item normals so blood does not sink into the flat side of a sword with Epic Fight 21.17.

Bodies and views

• Fixes the vanilla player model briefly appearing clean while crouching, standing up or washing blood off in rain.
• Fixes body textures stopping updates after rejoining, respawning or reloading an entity.
• Keeps separate blood textures for the entity's own model, Epic Fight's model and Epic Fight's first-person arms so they do not overwrite each other.

Held items

• Gradual rain, drying, snow and fire updates no longer trigger repeated first-person item movement or restart block breaking.

Coverage and limits

• Raises the blood limit on items and placed blocks from 1,024 to 16,384 pixels, matching bodies. One hit still adds at most 1,024 pixels.
• Soot and soaking can cover the whole model.
• Ground mud stays on the lower body, covering about a third of the model; frost and snow also cover about a third.
• Dirt other than soot covers at most 38% of an item or armour piece.

Performance and validation

• Forge no longer parses an item's blood and dirt data on every draw.
• Held and inventory items reuse history per slot instead of per synchronized stack copy.
• Gradual water, dirt and washing changes redraw at most twice per second per body or item. New wounds bypass that interval.
• Removes diagnostic log lines from the test builds.
• No new FPS measurements were made for 2.9.1. Earlier 2.8.3 benchmark results do not measure this release.
