The FlagMaster package ships with a few example textures for the Atlas Generator, albedo and normals only. Your own flag textures are up to you, either from an artist or from AI image generation.Be aware that you need to know how to author a PBR texture set. If you don't, an albedo/diffuse texture is the minimum, both for the Atlas Generator and for the shader itself. In that case you lose the PBR capabilities.Else, you get a full blown flag system that can be stripped down in its material settings to the minimum of just having an abledo with no other effect, procedural, which gives you the possiblity to set hundrets of flags via GPU instancing, working on mobile too.PipelineUniversal Render Pipeline only, Unity 6 (developed on 6.4 LTS)Forward, Forward+ and Deferred renderer pathsShader target 4.5ForwardLit pass tagged UniversalForwardOnly, DepthNormals tagged DepthNormalsOnlyShader passesForwardLit, ShadowCaster, DepthOnly, DepthNormalsMotionVectors, XRMotionVectorsSceneSelection and Picking (editor only, stripped from builds)Identical vertex deformation across all passes, single shared sourceCloth solverCompute shader, 6 kernels, 256 threads per groupVerlet integration with distance, shear and bend constraintsConfigurable substeps (1 to 8) and solver iterations (1 to 32)Ping pong buffers, scheduling independent and frame deterministic8 ComputeBuffers per flag instance, float3 world space positionsNormals and tangents computed on the GPUNo CPU readback, no runtime mesh writesRequires SystemInfo.supportsComputeShaders, falls back with a clear warningMeshRuntime generated grid, 2 to 128 subdivisions per axisVertex count = (subdivisionsX + 1) × (subdivisionsY + 1), up to 16,641Static mesh cache shared across all instances of the same resolutionBatchingProcedural mode: GPU Instancing via MaterialPropertyBlock, or SRP Batching via material instance, auto detected from the materialCloth mode: one draw call per flag, batching disabled by designInstanced properties packed to minimise per instance constant buffer sizeMotion vectorsPer object motion vector generation mode set automaticallyProcedural: previous frame reconstructed from previous time, wind and object matrixCloth: dedicated frame history buffer taken before the first substepCompatible with TAA, motion blur, DLSS, FSR and STPKeywords and strippingAll feature keywords are shader_feature_localPer material stripping checkboxes in the custom shader GUIUnused features compile out completely, including their interpolatorsCodeC# with assembly definitions, runtime and editor separatedExecuteAlways component, full edit mode previewNo coroutines, no per frame allocations, cached property IDsGlobal fallback buffers for material previews, thumbnails and picking
