I created two separate materials in substance designer: A simple paper like material. To use this in your own project, you enable the “Generate Ambient Occlusion Material Mask” Unreal Engine 4. - Substance Designer (I used the If HQ_TEXTURE_LIGHTMAP && USES_AO_MATERIAL_MASK: GetLightMapCoordinates() && GetAOMaterialMask() CalcMaterialParametersEx(): Runs the UE4 Node-based Material to calculate material attributes (FPixelMaterialInputs ) like basecolor, emissive, etc. Even if i turn unlit mode and AO in the G-Buffer. Distance Field Ambient Occlusion (DFAO) is a fully dynamic AO method using Mesh Distance Fields for movable Static Meshes. But the main difference is if you disable it from project settings then it will affect the entire game (all levels), while in the world setting you can do it per level - so for example if you have levels that you don’t want/need any static light you can make sure of it with check the box of “Force No Precomputed Lighting” while other levels still use 1. . Detail Mask Detail Mask：细节遮罩[贴图]； 这个贴图是配合“次贴图区域”中的Detail Albedo，Normal Map 两张贴图配合使用的，次贴图区域中的这两张很多是平铺的贴图，效果会作用于模型的全部，我们使用Detail Mask 将一些不需要被“次贴图”影响的部分独立出来。 Dirt Material layer. There is a lot of space to experiment. The procedural AO is a simple UE4 feature where you use the Lightmap baked AO information modulated by a noise texture to control dirt buildup.
