Description

Two 3D models made by Blender 2.93.1.


The barrel model is made by following Brackeys' tutorial video from YouTube. It has a single material with the texture image combined base color and ambient occlusion.


The model is made reference by the photo above. It has a single material with the texture image combined base color and ambient occlusion.


Base Color Texture

The base color texture is the plain color of the model.


Ambient Occlusion(AO) Texture

The ambient occlusion texture is rendered by Blender, it simulates the shadow that is a deep dark area surrounds by meshes to an image that could apply to the model, it gives more realistic to the model without a dynamic light, since a sealed area with non-opaque material will never have light goes in.


During this task:

  • Ambient occlusion texture was rendered incorrect because the normal direction of the mesh is the wrong way around, it causes incorrect normal direction mesh always result in full shadow effect of AO texture.
  • When two islands of UV overlapping to save space for UV map of the texture, renderer  AO texture causing unexpected shadow effect on some areas.
  • The newest version Blender 2.93.1 only able to bake  AO texture by itself, used Shader Editor MixRGB multiply node to combined color and AO texture to one for display.
  • Uses node in shader editor to mix base color texture and ambient occlusion texture, then bake into a new texture with Diffuse bake type and color contribution checked only.
