here is an exterior scene rendered with 249b

The images are globally nice, but I see an obvious UV mapping error on the edges of the square pillars. In fact it is a very common error seen when stones textures are used : When mapping a stone texture on a wall or a pillar, it is better to not map from view and not use cubic mapping as well if you don't want to have the stones not aligned on the edges.

The best way is to fully UV unwrap the pillars, or even map a flat surface, make loopcuts, and then fold the surface along the loop edges you have created. This way, the stones will look realistic in the angles of the walls and pillars.

thank you roubal for your coment
the truth is that my mapping knowledge is limited...the advice you gave is for blender?I use archicad and then rhino for modeling...

I use Blender, but I think that the method is similar in any 3D software allowing UV mapping...

I don't know Rhino, but a quick search on Google seems to indicate that the way UV coordinates are applied in Rhino don't make things easy. It seems to be a nurbs modeller, and for the few I have read it would apply UV coordinates for each face created. Not globally.

This said, if you create a flat surface made of 4 faces (for a pillar), I'm almost sure that you can align the texture along the edges and then fold the surface to make the pillar volume.

ok,I think I got it.
thank you.

It can be photo real to the untrained eye
Nice render, however the part of the house which is just white, desperately needs some texturing of some sort or a ruff stone normal/bump map

well there is a bump stucco map, but it probably needs more strength....
thanks for comment
