Ok, I have transferred about 90% of the relevant celtic buildings into .blend files ready for ORGE3D export.
It's quite amazing how all these different buildings basically only use one single texture (which comes in two versions, one with snow and one without).
Next I need to figure out how to get them into SumWars (which seems to be the hard part?).
Btw: There are actually some coastal buildings and a lot of nice looking ships that could be used as props... does SumWars have the ability to add water to the levels? Probably not, right (as it is all flat currently)?
I will probably also convert all the "nordic" vegetation from 0 A.D. so that together with the celtic civ set we have a nice "viking" themed set for SumWars.
However we really need some sort of terrain implementation, since without the nice blended ground textures from 0 A.D. everything will look really out of place on the green flat ground
