    VRAY light baking

    Hi
    There is 3ds max + VRAY scene I want bake the lighting on textures using built-in render to texture, the target is export baked scene to Unreal Engine.
    My question here:
    What is the right element I should use to bake, VRAY Diffuse or VRAY Light Map or VRAY Total Light Map or VRAY Shadows or VRAY GI ..!
    p.s.: I need only bake lights and shadows without bake reflections or other elements

    Regards

    I don't want to discourage you but some people have done it in the past and the results were not very good... compared to a baked scene by lightmass directly in unreal. Good luck anyway.

      There is no way to bake lighting correctly outside of UE4, Vray can definitely do a better job(with longer render times) but it's not equiped to render lightmaps for UE4.

        Yes but what some people have done is to bake lightmaps in vray, import those maps in unreal and kinda ''blend'' them with the diffuse maps or something like that in the UE4 material. Awful workflow of course.

          UE4 really needs a way to import/export lightmaps, cos lightmass isn't great.

            I find lightmass pretty good. You just need good computing power if you want to bake huge scenes tho!

              I've tried to do this in the past with a plug in called "Flatiron" and believe me, it is faster and easier to build all of your light inside UE4, it's not easy at first because it's a new program you've gotta learn after all, but after a while you'll get vray-like results.

                The reason it isn't supported is that UE4 lightmaps have directionality to them, and their lightmaps support up to 3 overlapping stationary lights with the ability to change color and intensity in game (along with as many static lights as you want).
