- added a simple and fast clear path of the material buffer - light and env light passes now reads AO and isStrataMaterial from the StrataHeader. No longer reads the classification or gbuffer data. - Handle the max BSDF count case from the compiler. Clear est 0.1ms at 1080p SkyEnv pass cost 0.7->0.6ms et occupancy 60->70% #rb Charles.deRousiers [CL 15364191 by Sebastien Hillaire in ue5-main branch]
