PN-AEN Crack-Free Tessellation Displacement

(Documentation) :: (Forum Thread) This is the Standard Unity Render Pipeline version of CFTD, for HDRP you might want to check out: CFTD [4] HDRP CFTD 2.0 has been completely re-written from the ground up! Now with PN-AEN tessellation, GPU instancing and much more! The Crack-Free Tessellation Displacement Shader for Unity. This tessellation shader uses buffers to calculate and remove displacement errors at UV discontinuities. Important: CFTD 2.2 is not compatible with previous versions. Demo scene is no longer included. CFTD does not fully support skinned meshes. New in CFTD 2.2: * CFTD now supports Vulkan. * Improved mesh swimming reduction (displacement miplod). * Better support for baked displacement maps. New in CFTD 2.1: * CFTD now supports OpenGL 4.5. * Even better shader performance. New in CFTD 2.0: * Supports PN-AEN Tessellation (adds geometric detail and smooths meshes, while persevering hard edges). * Supports GPU Instancing (helps with reducing batches). * Full support for Unity's PBR workflow. * Better shader performance. * AAA, industry-grade reduction of adaptive tessellation artifacts (an issue known as 'mesh swimming'). Features (inherited): * Distance Based and Edge Length adaptive tessellation. * Patches up displacement cracks at UV seams. * Smooths normals on the edges between smoothing groups (hard edges) in a very neat and unique way (Distance Based). * FOV-dependent (Edge Length). I.e. supports camera zooming-in. * Shadow caster LOD (as of 2.0 in Deferred Rendering only). * Supports Unity's GI. * Works with your existing assets. * Casts and receives full shadows. * Includes a non-GPU based mesh subdivider. * Performance-friendly. * Full source code. * Easy to use. Limitations: * CFTD does not support skinned meshes (you can apply the shader, but it will not be crack-free). * DirectX 11 / 12 + OpenGL 4.5 & Vulkan (Metal support has not been tested). * Cracks are gone at runtime only. * No static / dynamic batching (but supports instancing). * Please check the documentation before purchase. Don't care about Crack-Free, but rather need something Charge-Free? (Free Tessellation Shaders)
