Please send me your current code.

As you know the plugin framework is not completely finished yet, so you may 
need to add hacks and workarounds to the plugin.

No, I will add a member to the serializer that points to the corresponding 
format.

Why do you need to access the format before serialization? The serialization 
method should be registered once at plugin loading time.

Hmm, there are some problems.

When exporting a scene, the file name is known before serialization. But when 
a scene is rendered, the scene is serialized into a buffer. The povray render 
widget saves this data to a temp file after serialization, not the part.

And the file can be a remote file on a ftp server, it does not need to be a 
local file. Don't you think it would be an option to generate the landscape 
as a mesh with (smooth?) triangles?

Greetings, Andreas
