00:09 - Discussing on lightmaps We create a 1m by 1m by 1m box in 3ds max.
When we import this box into unreal engine, it creates an unwrapped UVW map to store lightmaps.
When we build lighting, the shadows are stored in these lightmaps.
Because we use a small lightmap resolution, the shadows are not so nice.
using boxes to represent the interior scene, we realize that only the walls facing inside are important in an interior scene.
We detach the inner side of these walls so that it has its own lightmap and not shared with the other 3 sides of the wall. This also allow us to increase the lightmap resolution of the inner side of the wall without having to increase the lightmap resolution for the other 3 side as we dont need it.
With these we start detaching important meshes.
07:48 - Exporting 3ds max file
Before we export we just renamed the windows glass so its easier to assign materials in unreal engine.
For grouped meshed in 3ds max, we can edit each mesh individually by using the open options
Once we renamed, we export the 3ds max as a unreal datasmith file format.
09:24 - Importing into Unreal Engine
We will be using version 4.22 in this tutorial.
Launch a new project.
Create folders that we use often
Import the models using the datasmith importer
Create a sky material to create a white background for our scene
Create a simple white material to be used later. Use a constant 1 and attach it to the base colour node in the material.
15:56 - Fixing UVW maps
Some of the meshes does not have proper UVW maps. Lets fix them in 3ds max.
These are the meshes where we fix the UVW maps. You can check out the 3ds max models on what UVW maps we use on these meshes as we did not show everything in the video.
-Detached walls
-Window walls
-Stair railings
-Bay window
-Steps
-Stair railings
24:20 - Adding in the rest of the necessary objects
We assign a white material to all our mesh.
We add a lightmass importance volume to 'tell' unreal where to focus the light building on
We add a lightmass portal to 'tell' unreal these are the windows and to direct the photons from the light outside into the interior through these windows.
We add a box reflection capture
We add a static skylight, using a HDRI already in unreal
We build the light.
