Turn On Vibrant Visuals So Dynamic View Shader Looks Its Best
The pack's own description says that turning on the Vibrant Visuals option helps its visual effects work better. If the shader looks flat or weaker than in the screenshots, check this setting first.
Enable Vibrant Visuals
1. Open Settings from the main menu or the pause menu.
2. Go to Video.
3. Find the graphics mode option and switch it to Vibrant Visuals.
4. Leave the menu and let the game apply the change.
Vibrant Visuals is only offered on devices that support it. If you can't find the option, your device may not have it. In that case the pack's effects may not show as fully as intended.
Combine it with the shader
1. Make sure Dynamic View Shader is in your active packs, either under Global Resources or in the world's Resource Packs list.
2. With Vibrant Visuals on, load a world. Stand somewhere with depth, like a hilltop looking over terrain, and compare the view to before.
3. If performance drops too much, try a lower intensity in the pack's settings before you give up on Vibrant Visuals. That keeps the improved look while easing the load.
If you switch Vibrant Visuals off later, the shader may look different. Turning it back on brings back the intended appearance.
