I needed the same thing, so I opened the generate.py and added these lines (see below) bellow just before comment “# Generate tiles”. It makes the code execution stop and wait for ENTER after the faces are generated, but before the tiles are generated. In that time, you can edit the nadir/zenith areas.

code to insert:

# Wait for (nadir edit)
raw_input(‘Faces generated, press Enter to continue’);

If you read the blog post you linked to carefully, the author notes that a modified version of the generate.py script was used. My version of the script does not support the feature you’re asking about, which is why the --r2c flag doesn’t work.

Let me concretize it…

Using generate.py I get a cubic version of the panorama. But what I would like to do is, generating a cubic version, modifying the floor and converting it back into a multires panorama.

On the blog http://blog.trumpton.org.uk/2015/06/building-tour-with-hugin-and-pannellum_45.html I found a description how to convert a panorama to cubic via “python generate.py PanoramaDirectory –r2c InputImage.tif”

But generate.py doesn’t know the parameter –r2c.

Any suggestions?

You want to use the minPitch and maxPitch parameters. See https://github.com/mpetroff/pannellum/blob/master/doc/json-config-parameters.md.
