    This is the Part 2 of Speed Modeling a House in 3ds Max for Unreal Engine.
    It covers polygon count reduction, UV-ing, and importing into Unreal Engine.

    ...maybe it's good for games but sadly it's not ideal for achviz: all your walls are one single mesh! :S You can't set a high enough lightmap resolution to achieve detailed, realistic results!
    Thank you! Good to know that! I'm going to break that apart then.

    Finally i figured out how to fix my first problem, jaggered shadows.
    You must have your uv island at 90 degrees.
    i don't know why Steamroller script has turned my uv at ~30°.

    I had to Flappen Mappings manually to have nice shadow in my ceilings

    Hi, i've one stationary directional light, One static skylikght hdri and One BP_SkySphere. Walls, floor and ceiling are all single planes in different meshes. I've alredy tried to push lightmap size up to 1024 for walls and ceiling, with no results. The weird thing is that in other rooms my shadows are all a soft straight line.

    I'm using multibounce skylight lightmass.exe (4.17 version) for light baking.

    My Indirect lighting smoothness is set to 1.2 and every windows have a light portal on it.
    Maybe i could change UV island's padding...

    I would try to adjust indirect Lighting smoothness. Its in your world settings.
    You can also make sure your directional light is set to stationary.
    Then if your not satisfied look at your lightmap resolution in your mesh settings.
    It should help. The ceiling is a combined mesh with your walls?

    Thank you guys, i'm really excited by results obtained so far. I've other question, maybe borderline for this topic. Now i'm stuck with jagged shadow on some meshes edge.

    And what is going on with this furniture reflection/light bounce? It seems like an emissive material but is only a rough (0.85) wooden mesh

    System Unit Setup button made my day. Thanks a lot!!

    In UE4, the default units is not the cm ?

    Oh... now i have weird behavior in export from 3ds max 2018 to fbx... from sketchup i'm saving file in sketchup 8 skp format (i work with millimeters), import in max with Units setup (millimeters) and it's all right. But when i export in fbx it doesn't matter which choice i do in units tab.... it will always is REAAAAAALLY big (it seems like 10 times) ...

    I manually unwrap UV channel 1 (texture/ normal channel) and steamroll UV channel 2 (lightmap channel). If a texture looks good on your mesh, then the flattened UV channel 2 will be fine in UE4.

    Danimal8361, I also use a Sketchup to 3ds max workflow but i stuck on UVWMAP for objects with mesh complex (sofas...). Do you use steamroller for all or do you use UVWMAP manually ? And yes, the newer versions of 3ds max imports SKP files easily.
