Better Chroma Key FAQ
10 questions players actually ask, answered.
How do I find the colored blocks after installing the mod?
The colored blocks are found in the Creative inventory under a dedicated tab or category. In Survival mode, you can craft them using the recipes shown in your crafting menu, or find them in the mod's creative tab if you have cheats enabled.
What's the difference between regular and light-emitting blocks?
Regular colored blocks have no light output and blend into dark environments, while light-emitting variants produce their own light source, making them useful for creating glowing backgrounds without needing separate lighting rigs.
Can I use these blocks with any video editing software?
Yes, the blocks work with any video editor that supports chroma key (color key) removal, such as OBS, DaVinci Resolve, Adobe Premiere, or similar software. You may need to adjust the color tolerance in your editor to match the exact block color.
Do the colored blocks work with shaders?
The blocks render normally with most shader packs, but some shaders may alter their appearance or add effects that interfere with chroma keying. Test your specific shader combination before recording important content.
Which color block is best for chroma keying?
Green and magenta/pink are the most common chroma key colors and work well with this mod's blocks. Choose whichever color appears least in your recording subject (the mob or player you're filming).
Will a large backdrop of these blocks cause lag?
Large builds can impact performance depending on your system and render distance. Use the light-emitting variants strategically to reduce the need for additional lighting entities, and consider limiting backdrop size to what fits in your camera frame.
Can I dye or customize the colored blocks?
The blocks come in fixed colors and cannot be dyed or modified further. If you need a specific shade, check if the mod includes that color variant, or use your video editor's color range adjustment during chroma keying.
Do these blocks have any special properties or drop items?
The colored blocks behave like standard solid blocks—they drop themselves when mined and have no special mechanics. They're designed purely for visual purposes in recording setups.
How do I match my backdrop color to my video editor's chroma key settings?
Record a short test clip of the colored block, then import it into your editor and apply the chroma key filter. Adjust the color tolerance and threshold until the background removes cleanly without cutting into your subject.
Can I use these blocks in multiplayer or do they require single-player?
The blocks work in both single-player and multiplayer worlds. On multiplayer servers, make sure the mod is installed on the server or enabled for that world; otherwise, other players won't see the blocks you place.
