This changelist is a merge of work done in //UE5/Dev-ParallelRendering to remove tech debt in the SRV/UAV create functions. See individual changelist descriptions in that stream for further details, but a summary of the change is as follows: - We had multiple overloads of each of the RHICreateShaderResourceView and RHICreateUnorderedAccessView functions. Each function had a different set of supported view types and using them was complicated / ambiguous. - There's now only 2 create functions, and a common FRHIViewDesc descriptor struct, which is stored on the base view class. - FRHIView takes a reference on the underlying resource, ensuring that RHI views keep their viewed resource alive. This was not the case on some platforms, since it was previously the platform RHI implementation's responsibility. - Platform RHI implementations resolve an FRHIViewDesc into a full FViewInfo struct using GetViewInfo. This centralizes the logic for computing num mips / num slices / format etc so it is the same across all platforms. - Views must never be created with nullptr resources. This used to happen in the mesh streamer, but now all views require a real underlying resource. That resource can be a "BUF_NullResource" buffer, which is what the mesh streamer uses as a placeholder for buffers that have not streamed yet. - We will eventually replace FRHITextureReference with a "null texture", similar to how BUF_NullResource works for buffers. This is not yet implemented, so there is no "null view" of a texture currently. #rb kenzo.terelst,jeannoe.morissette,dmitriy.dyomin #preflight 643534642855180717af410e #jira none [CL 24989901 by Luke Thatcher in ue5-main branch]
