Displacement map is pixelated & useless?

I'm finding that exporting a displacement map is not getting the results needed. As you can see in the picture from Blender, the displacement map is all pixelated and useless really -- it doesn't add any additional depth or anything. What am I doing wrong in this process?

Here is my workflow:
1. Unwrap object
2. Retopo room > file > export retopo object
3. Retopo room > bake > bake into normal map for per pixel
4. Paint room > textures > texture baking tool
5. Input: Choose the .obj exported from step 2.

Thanks much in advance!




Here is a link to the .3b file.

Hey Digman, thanks for all of this. I can tell you really put the effort into getting me this info.


However, I am still lost. I looked at the video but that is for an older version of 3d coat, and those menu items don't exist anymore.


Here is the new workflow I tried, but still it didn't work out:

1. Retopo room > bake menu > Bake w/ per pixel w/ displacement

2. Paint room > texture editor > switch to displacement map UV set
3. Textures menu > export > displacement map of visibile layers > choose correct UV set
If you could give me a similar workflow, using steps like I did above, that would help me out a lot.

Alright I looked through your post more, and tried the following steps:

1. Retopo room > Bake for micro vertex
2. Paint room > export objects and textures


However, all the textures come out blank -- there is not displacement map on them. Do you know why this is happening?

Baking using Per Pixel with displacement works as well... Artist call... Test both ways and use the displacement map you like best and workflow or a combination of both plus sometimes I will use micro-vertex for the displacement and then the bake regular per pixel normal map though I will subdivide the model to the same amount in the baking  panel as I did for the displacement map. . The workflow chosen depends upon the model and the intended use.


Attached image shows my Per Pixel with displacement baking panel and the other image the exr result on this simple test..
