Blender painted bricks, with bump map. Stone and concrete, GIMP created images with bump texture in blender.
The stones and bricks came to life for me with the application of bump texture. The concrete still needs something more.
I have also been doing some work on the siding.
The section with the window is larger planks of wood and each board has geometry. The uv is aligned so the shadow is only on the bottom of the board. The smaller planks are image texture on flat geometry with a bump map.
I am not sure that either is the final solution. I am excited to move on to the next lecture.
