Apply Dynamic View Shader to All Worlds or Just One
You can run Dynamic View Shader everywhere or only in the worlds where you want the sharper look. Both use the normal resource pack menus.
Apply it to every world
1. Open Settings, then Global Resources.
2. Find Dynamic View Shader under your available packs.
3. Set the intensity in the pack's settings first, since it is chosen before the pack is applied.
4. Activate the pack so it appears in the active list.
5.
The shader now applies to every world you open.
Apply it to one world only
1. On the world list, tap the edit button next to the world you want.
2. Open the Resource Packs section.
3. Pick your intensity in the pack's settings, then activate Dynamic View Shader.
4. Load the world.
This keeps your other worlds looking like vanilla. It works well if you only want the dramatic look for a showcase build or a scenic survival world.
Quick check
Once you're in the world, open Settings > Video and turn on Vibrant Visuals if your device supports it. The pack says this helps its effects work better. Then look at a detailed landscape. It should look noticeably sharper and more dynamic than before.
