Phero Visuals is a shader pack, so it runs through a shader loader such as Iris or OptiFine. It does not go in the resourcepacks folder.
Loading the pack
1. Launch Minecraft with your shader loader active.
2. From the main menu or the pause menu, open Options → Video Settings → Shader Packs.
3. If Phero Visuals is not in the list, click the button that opens the shader pack folder. Put the pack file in that folder and leave it as it was downloaded. Do not unzip it.
4. Return to the game and select Phero Visuals from the list.
5. Click Apply or Done. The screen may freeze for a moment while the shaders load.
Confirming the pack is active
Load into a world and check for the pack's main effects:
- Shadows: Stand in sunlight near a tree or wall. You should see soft shadows on the ground from blocks, trees and your own player.
- Water: Walk to an ocean or river. The surface should show clear reflections.
- Bloom: Place a torch at night or look toward the sun. Bright lights should have a soft glow around them.
- Sky: Look up. The clouds should look different from vanilla, and the sky colours change as the day goes on.
You may see none of these and the world looks like plain vanilla. If so, go back to the Shader Packs screen and make sure Phero Visuals is selected, not "Off" or "None".
