What is ambient occlusion texture?
An Ambient Occlusion (AO) map creates soft shadowing, as if the model was lit without a direct light source, like on a cloudy day. Typically the AO map is blended into the metalness or specular map, instead of being stored as a unique texture, because this saves memory.
What is render to texture?
Render-To-Texture is a handful method to create a variety of effects. The basic idea is that you render a scene just like you usually do, but this time in a texture that you can reuse later. Applications include in-game cameras, post-processing, and as many GFX as you can imagine.
Where do you connect ambient occlusion blender?
In the render layer node, you will have an AO output. connect it to a color ramp node and the colorramp to the bottom socket of a mix node. Then set the mix node to multiply. Connect the image to the top color socket in the mix node and the mix node to the output.
What is ambient occlusion blender?
Ambient Occlusion is a sophisticated ray-tracing calculation which simulates soft global illumination shadows by faking darkness perceived in corners and at mesh intersections, creases, and cracks, where ambient light is occluded, or blocked. You must have an ambient light color set as you desire. …

How do you get textures in blender?
How to add a texture in Blender? Go to the shading tab, drag and drop an image texture into the lower portion of the interface.

How do you use Ambient Occlusion?
How to use ambient occlusion
- The first step is to render the scene with just the sun light and Ambient Light set to 0%.
- In the second step the Ambient Light is set to a much higher value.
- For the first two renderings it is OK to use methods for creating fast renderings.
- In the third step, ambient occlusion is added.
