# Objective Fixes #6952 ## Solution - Request WGPU capabilities `SAMPLED_TEXTURE_AND_STORAGE_BUFFER_ARRAY_NON_UNIFORM_INDEXING`, `SAMPLER_NON_UNIFORM_INDEXING` and `UNIFORM_BUFFER_AND_STORAGE_TEXTURE_ARRAY_NON_UNIFORM_INDEXING` when corresponding features are enabled. - Add an example (`shaders/texture_binding_array`) illustrating (and testing) the use of non-uniform indexed textures and samplers.  ## Changelog - Added new capabilities for shader validation. - Added example `shaders/texture_binding_array`.
