HI … I was an architectural designer I am using SketchUp for lot of years…but after seeing Blender in action I would say that this is the best software I ever used … I started building projects in blender …but in mean while I saw the unreal engine software and it turned me so interesting …due to it has light baking capacity for the entire scene…what I meant is only one time baking for unreal engine…but as for Blender you should do for every material…this kind of time waste for me… I am hoping that in future there will be a one time bake for the entire scene similar to unreal engine…please view my request and thank for the developers.
