Chroma Keys by Arspective
by Arspective
Chroma Keys by Arspective adds 27 solid chroma key blocks in nine colors, each in normal, glowing and no-shadow forms, for green-screen work.
What it does
The blocks are flat, pure-color backdrops meant for filming, machinima, screenshots and thumbnails, where a single-color background keeps the subject simple to cut out in editing software. Every color is a saturated tone that keying tools can pick out reliably. The no-shadow variant stays visually flat under any lighting, which matters when a build's own light sources would otherwise cast shading across the backdrop.
Standard wool and concrete blocks are a poor substitute because their color shifts with lighting and the exact tone is not a usable green screen color. Chroma Keys removes the crafting cost from the problem: a player places a block and starts filming. Fabric API is required, and the mod is published for Fabric only, with files for 1.21.11 and the environment set to client and server, so the server and every player need it. Its license is the MIT License and the project is not open source.
Key features
27 chroma key blocks
Nine colors are offered in three forms: normal, glowing and no-shadow, giving 27 blocks in total.
No-shadow variant
The no-shadow blocks keep a flat appearance regardless of the lighting around them, so the backdrop stays one consistent color.
Glowing blocks
Glowing versions stay bright in dim scenes, where a plain block would fall into shadow.
Placed for quick setup
Each block is placed like any other, so a backdrop can be built in seconds during a session.
