yeah i was quiet busy and progressed only slowly with this
I had to completely rework the material export section as we now export the materials from the python GUI.
I'am sorry, i haven't realy understood the problem you mentioned
- so let me in place describe shortly how the material-editor works: for each material in blender there's a indigo-material with same name. Whenever you build your scenes you have to create blender-materials as usual but if you don't use blenders-internal-renderer you don't need to setup them. We only need the blender-material-objects as interface for indigo-materials. In the indigo-GUI you then select the material you like to edit from the drop-down-box where all material-names are listed. Below that you then can see current indigo settings for the selected material. Currently I have the GUI for Diffuse, Phong, Blend, Specular+basic-mediums, Glossy-reflection and some basic SSS. Also theres a special material-type for lights. What ever you set in the python-GUI gets stored inside the blender-material-objects with the advantage that all indigo-stuff gets saved inside the ".blend" file. Once you have setup your scene you hit the Render-button as before and the objects, meshes amd materials gets exported to indigos-XML for rendering.
I'am not sure if I have disposed your mentioned problems Wedge but most is ready and working... as mentioned, there are some special materials settings that i haven't yet build the GUI for as phase-functions for SSS and other complex stuff...
Also I'am still looking to solve the ortho-matrix-limitation... i have some ideas but they are quiet heavy to implement
The changes in exporter are quiet heavy and so there is many rewriten code that carry us back to the discussion of team-development
So I'am realy SORRY guys but this is once again a "one-man-show-development"
and so it should NOT be assumed to be the successor of the famous Blender-2-indigo-exporter!
It's a new toy, a indigo-material-editor-for-blender-with-indigo-export (i call it Blendigo
) and it will be open-source as all Blender-2-indigo exporters and everyone can copy/paste and modifiy to their needs
I will start a "Work-in-progress indigo-material-editor-for-blender" thread here soon with a first beta-source for testing-purpose as i'am sure there's still much to do/fusion
