- Now it gets weight data and use that weight data without recalc in eval - Also made montage instance's members to be private - changed single node to get weight and use that weight for eval - same as normal anim BP - changed update weight of montage to happen before native update animation Merging //depot/UE4-Orion/Engine/Source/... to //depot/UE4/Engine/Source/...
