I have this mesh with 7.5 million vertices:

high poly mesh

And I also have a low poly version of it with 5 thousand vertices:

low poly mesh

I just want to bake the detailed height information of the high poly model into a displacement map that I can use on the low poly model. Baking a normal map works just fine, but there is not option for baking actual height information:

baking options

I found out that I can enable "Experimental" feature set for Cycles and then I have a "Displacement" option under "Bake from Multires". But there is not option to bake from selected to active, what I need.

baking options

If this is not possible in Blender what are my options?

Update 1

As suggested by Manu Järvinen I have tried using Blender 2.7 to do the displacement baking, but after baking is done I get a single-colored texture:

plain texture

Initially I though this is an issue with the "Distance" but changing it does not help.

  • $\begingroup$ Yeah all normals should point in the right directions (event baking a normal map works perfectly fine) and if you mean the distance under the "Selected to active" checkbox: yes I tried several values without any better result $\endgroup$

1 Answer 1


You should be able to use Blender 2.79b for baking the displacement until it is available in 2.8x


Thanks for sending the .blend - it seems that your model was too small

enter image description here

So, when I scaled it to be roughly dimensions x=15, y=12 and z=8 and then applied the scales for both objects CTRL+A, the baking was successful with the values Distance: 0 and Bias: 0

And, you get even greater results if you scale it then with 10 and apply the scales.

  • $\begingroup$ Do you know why they removed it from Blender 2.8? $\endgroup$

  • $\begingroup$ Not really. My guess is that they are going to add it when they find time - maybe it wasn't a piece of cake to port it from 2.79.... $\endgroup$ Mar 8, 2020 at 18:02
  • $\begingroup$ Ok makes sense :) $\endgroup$

  • $\begingroup$ For some reason the baking outputs a one-colored texture. Do you know why? (I've updated my question for more details) $\endgroup$
