Multi-material models from the store have been the real subject of todays grafting, with the entire city pack built on these foundations. Not necessarily loading them in, which works fine, but light mapping them. The currently lightmapper was strictly designed handle one light map object per one entity, but the MM models could have any number of objects for a single entity, each with their own texture.
The current build as of Friday could take a single material from the model and lightmap it, discarding the rest. Monday was about allowing the lightmapper to discover the rest and include them in the process. As the old system was a one-object based system, everything needed updating, the data structures, the load and save, the consolidator, the lot.
This is my progress by 9PM, with all six materials separated, submitted and lightmapped (to some degree). I have an all day meeting on Tuesday so cannot stay up too long, but I think I am over the hump now and it's just a case of calming down the shadow objects, restoring the floor plane, e.t.c. Slowly slowly, catchy monkey!
App Game Kit 2 continues to do great on Steam, and is providing useful information and statistics to help us plan our Reloaded launch early next year. For more info on AGK2, here is the Steam page: http://store.steampowered.com/app/325180/
Going to put another hour into finishing the lightmapping of MM models, and then make a build for the meeting show tomorrow. The agenda is quite full so need plenty Z's so I don't fall asleep half way through, but rest assured on Wednesday the fixing continues as I make my way though the list of items fed back from the weekend alpha testing.
