Texture/ Material Problem

[architect-sma]

I'm having a material map/ tiling problem. I am trying to apply a stone material to the base of a building. The walls are almost all straight in plan, except for one area where the walls turn to a 45 degree angle. When I try to put the material on the whole base of the building it maps fine everywhere except on the 45 degree angled walls. On that 45 degree wall the map is being disorted into what looks like polygons. I have assigned the UVW Map as a box, and can't find any other way to map it so it won't distort. Could anyone please help? I have attached a very rough rendering showing the problem.

I'm not sure but can't you select individual polygons and apply a different UVW Map to it? Select the object, convert it to a polygon mesh or something, select the polygon you want to modify then apply a UVW Map to the polygon. Do that for all polygons you need to tune the map.

I'm not a Viz user (altough I've tried it) but I think that's the way to do it.

It looks like the material/mapping is set to face. This could be in the material(at least in max), called face map in the basic parameters. Also, this could be set in the objects mapping parameters--UVW Map modifier.

...I have assigned the UVW Map as a box...

He used the box projection in the wall. This would be fine if the wall only had 6 faces (as a normal cube). When there are other non-orthogonal faces the result is not as expected.

From the pic it seems you may have then used face mapping by mystake (when trying to fix it).

Either way, try to map the texture globally to the wall using box and then use face map with manual tunning on the other faces.
