You make yourself very clear, but 1: it is not always easy to mask a (complicated) building, and 2: you would have the same problem. Matt explained to me what causes the line, namely the light is measured in the micropolygons, but they are not infinitely small, so part of that poly may lay outside the infinitely thin wall. That's why a double wall would work, as the space in between covers those polys. If I make myself clear

I would add a plane floor and apply the ground texture to that...or are the micro polygons involved in the procedural plane as well.....if they are then add the floor in the model and do likewise to that. You'd only have bump not displace is the only downside.

That's a smart idea, but when you have a door opening, you can always see a little rise where terrain goes into floor, even though the colors and 'bump' may be kind of identical.
It's not a daily problem, so I'll think of something when the situation needs it. Thanks, Bobby.

It's the most I can do, hee hee hee
