- refactored the property binding representation, editor binding shave now more structure, and removed intermediate representation - added functionality to resolve property paths agains a known value - added instanced struct and object indirection types - added editor functionality to allow to bind to further than first level of properties - refactored editor tree traversal, allow to access values too - simplified statetree node ui - requires to recompile trees, bumped version #rb Mieszko.Zielinski #preflight 63e6204ff15c83b79312aca5 [CL 24117094 by mikko mononen in ue5-main branch]
