Unreal Engine: Making of Bright Interior - Tip of the Week

We're analyzing the scene 1 from Archinteriors for Unreal Engine vol. 4

This bright loft scene is a part of Archinteriors for Unreal Engine vol. 4. Check out all five scenes in Evermotion Shop. We poreted this scene from 3ds Max version, carefully optimized all the models, textured them in Substance Painter and re-created the scene using Unreal Engine rendering and lighting capabilties.

The scene consists of one main building and one additional building that is visible as a distant facade behind the windows.

The secondary building.

Floor mesh with UV map that is used for lightmap baking.

One of unique features of this scene are baked caustics. We baked them in V-Ray (because this scene comes originally from V-Ray) using caustics pass and then created a blueprint that gives this additional bit of photorealism for glass objects.

Rug was made with a material that uses Parallax Occlusion Mapping Node. Thanks to it, we have this "3d look" of it's texture.

 

Unreal_Engine_Archinteriors_4_1_018

Rug material looks complicated, but basically it's just mixing textures and controls their texture coordinates, the only thing that is unordinary is...

 

Unreal_Engine_Archinteriors_4_1_017

ParallaxOcclusion Mapping node. You can learn more about setting Parallax Occlusion in Unreal Engine from this tutorial.

ParallaxOcclusion Texture was made in Substance Designer by mixing procedural maps

All wooden construction elements are separated, to maximize texel density in scene. You should always consider separating elements when working with game engine. You can read more about texel density here

Why two skylights in the same scene ?
tootsie15:58:37  |  02-12-2018
Similar question: You are using BP_Lightstudio and I see the Sun is turned off in that blueprint, and that you are using a separate direcftional light sun. Why is that? Also, you are using the skylight in BP_Lightstudio, but you also appear to have a separate one as well. Why?? Tnx
