The last week i decided to rebuild 90 % of the cathedral.
Its exactly the same but with less faces, more precise and better lightning.
The better lightning is because i discovered that baking ambient occlusion is much better and much faster in the new blender 2.66
I baked it in 2.66 and usedthe result in 2.49b because i can only export it from there.
Its incredible, i was busy with this age for almost 1 year and did the rebuild in 5 days now i understand better how to do it.
For sky divers there will be some additional colliders, may be they are hard to find , but once know it will be very simple to use them and may be will add some fun for everyone.
It will give some views otherwise not possible without fly-mode.
like this.
