House for Black Rock

The first challenge for this bulding was that the texture dimensions were 2048/2048 pixels and two objects, two houses assigned. The good part for that strategy is the diversity of detailes contained in and no repetition texture ptoblem. The bad thing was the hard way of changing in progress, getting more detailes after starting. There would be no room for other detailes and if one would want to modify some parts of one building that would affect automatically the other building and a lot of extra work would be needed.

The second chalenge was the wood wall. This house is about 8.80 m hight. We were working under a common rule of no less than 128 pixels texture allocation for 1 meter on the geometry. So there would be a space of at least 512 pixels needed for such a wall. But there won't be space for other detailes. So I used a waist that surrounded the house in order to tesselate the geometry and to use a smaller part of texture. The waist hide exterior striations wall tiling texture. It was the house's waist that prevent the repetion of base texture dirt; I tesselated the wall under the waist and moved aside the UVW choordonates so that repetition is not noticeable. I does not matter if the actual wall cut is a seam because the waist covers it well.

But the problem was not solvet yet. There were another 5.8 meters wall geometry upper the waist that should be assigned by these 4 meters (512 pixels) of texture. It was the dirt moisture that had to be kept for the sick of diversity. So there was no way to make a realistic simple tiling with this image. I solved this by putted a tiling part inside and connect it so to avoit the seam. In the image bellow I darkened that tiling spots just to be perceviable (in real texture they are not noticeable).

The same thing I have at the roof, only ths time the problem were different. In order to catch the detailes of roof edge (marked with red) I had to tesselate the smaller roof surface. If I wouldn't have done it than the smaller roof would look too detailed because becouse it meassured only less than 3 meters and not 4 like the bigger one. So this time I had to make the tiling spots inside texture in order to get rid by 1 meter extra texture but to keep the upper and downer roof edge.
