I noticed when looking at another user's file, (using HDA2018)  how terrible his brick texture looked. So, I started a new plan, and drew a brick wall.  I changed the default brick texture to Red Brick 4 (library, HDA2018), and the pic on the right is what it looked like. Terrible! I then imported red brick 4 (as a new material) from the HDA10 library, and put it on a wall (pic on the left).  It looks just like it is supposed to (library preview image). Most of the other brick textures
