Amplify LUT Pack - 200+ LUT Grading Presets

IMPORTANT

• Raised minimum Unity support to 2022.3 LTS

• Raised minimum URP/HDRP support to 14x, or higher

LATEST HIGHLIGHTS

• Added preview support for Shader Graph (URP and HDRP)

• Added new Batch Baking tools

• Added Single Frame support to all Impostor types

• Added horizontal/vertical range and center yaw/pitch limits to all types

• Added official support for Unity 6.6

• Added preview support for Unity 6.7

• Added Publisher-signed packages

• Updated all templates per ASE 1.9.9.14

• Replaced the "Clip Neighbours Frames" toggle with an always-on clip

• Added GPU optimizations for Early-Z occlusion

• Fixed Impostor picking across the board

• Merged all 17.x versions into a single cross compatible asset

• Support for custom/non-standard HDRP and URP shaders (*)

• Default Bake Preset splits Emission and Occlusion textures

• Optional texture for Position to improve accuracy

• Improved impostor shadowing and surface intersections

• Increased max axis frames from 32 to 64

• Optimized shader variants to exclude unused textures

(*) Support for custom shaders is dependent on Deferred-mode compatibility. Forward-only shaders may require Custom Baking and Custom Impostor Runtime shaders.

NOTABLE FEATURES

• 1-Click Baking

• Octahedron and Spherical Impostors

TECHNICAL CONSIDERATIONS

Currently, standard baking is only supported if the shader exposes a Deferred path, such as Unity Standard shaders. However, the Impostors created can be used in both Forward and Deferred modes. Baking objects with custom shaders is supported via Custom Material Baking.

Lightmapping of impostors is not recommended, experimental uses are possible using Amplify Shader Editor; please examine our docs for details Official Wiki.

* Oculus Quest, and other Mobile-based VR devices are not officially supported.

* HDRP Translucent objects may not bake correctly.

1-CLICK CREATOR optimize your projects with ease by using next-generation Billboard Impostors.

IMPOSTORS are camera facing quads, or simple polygonal shapes, that replace complex geometry by rendering a fake 3D representation of the original object.

FLEXIBLE impostors can be moved, rotated, scaled, receive and cast shadows, intersect other objects or impostors, and can be used with LODGroup or any third-party LOD system.

MODERN technology making full use of GPU-based instancing. Providing Spherical and Octahedron Impostor techniques, the latter being capable of performing smart transitions between different views.
