How to Use an Existing OptiFine Sky Pack with Skyboxify
Skyboxify uses the same skybox file format as OptiFine, which means most OptiFine sky resource packs work as-is. You do not need to convert textures or rewrite properties files in most cases.
Installing the Pack
Drop the OptiFine sky pack into your resource packs folder just like any other pack, then enable it in-game. Skyboxify will read the skybox definitions from the standard OptiFine sky path automatically. Make sure the pack is enabled and sits above the default pack in the resource pack list.
When Something Does Not Show
If the sky stays vanilla, check that the pack actually contains a skybox definition and textures in the expected OptiFine folder structure. Some packs bundle skyboxes alongside other content, so confirm the sky files are present. Also verify no other resource pack is overriding the same files and winning the load order.
Combining with Skyboxify Features
Once an OptiFine pack is working, you can still use Skyboxify's own options such as blend modes, axis rotation, and rotation speed on top of it. These are read from the skybox properties, so editing those values lets you customize an existing pack's motion and layering without replacing its art.
