-FPostProcessRectParams was still using the old FTexture2DRHIRef/GetTexture2D pattern rather than using FTextureRHIRef directly. This meant that it did not support 2DArray textures, like the VR swapchain, and caused an assert during a post-process blur on Lyra. #review-20297934 #rb Arciel.Reckman #preflight 6287e5ff9b764703c31a4077 [CL 20300846 by Jeff Fisher in ue5-main branch]
