Hi I'm having a problem with baking textures. I have done one but I don't know how to add this texture to an object to speed up rendering. The texture is visible in Viewport Shading: Texture. But rendering is as slow as before. Is it possible to turn off shadows and other things for only this object with baked texture?

What you wan't to do is use an emission shade-less material:

In the material node editor, use a setup like this (The UV map is optional) It is important to keep the strength of the emission node down to 1

If everything in your scene is baked, use this to cut render times:

You can also avoid a-lot of extra calculations by cutting down on the samples and light bounces. You can set all of these values to 1:

Once you have the texture baked you need to assign it as an emission material to the object.

This is pretty simple:

  1. Go to the node editor
  2. Disconnect any nodes you have plugged into the surface socket on the material output node (you needn't delete them).
  3. Add an emission shader and an image texture node.
  4. Select the baked texture on the image texture node and plug it into the color input of the emission shader and plug the emission shader into the surface output. Make sure the strength of the emission shader is 1.00.

Note that if the camera is animated, baked glossy sharers will not look right.
