I am just trying , also a little bit of more light in the old version is lot of work.
I personaly don't consider this as being more work then lighten the old one.
The main difference is that i used a complete different way of lightning and used a python script to generate a fake ambient occlusion with vertex colors.
Its a script inside Blender in the paint area named" selfshadow vcols (Ao)"
You can change several parameters inside the script to adjust it to your needings.
You can see the result the best with a very light texture.
When it is done i can go back to my old texture and look how that one performs with these settings.
For those who did not noticed it, the groundplan of the cathedral is on the picture of the journal.
I have mainly showed photo's of the south wing.
All wings will be slightly different textured.
There is also a central hall from where you can reach the 4 towers and there is ..... more.
The picture Sirius refers to is in the West wing. and the windows you see there are inside windows to the central Hall.
So thats why you don't see clouds there.
I have not yet decided which way i go, i am still busy experimenting, thats the way i learn how to do it.
I realy hope i can releae the age , but there has to be wired a lot in this age.
That also takes its time.
Here another view with a different colored texture.
