Customer of the design project (Z) wants to look in two colors options for the walls for the children's room and bedroom
Dialogue in the ASCII:

Q: Can you tell us what is hard to do and what is easy mouse movement? I would have a child’s room and bedroom and in that, and in that color would have looked.
I: there you can make two options for each room, but it will just take twice the time to render - that is, I change the color of the walls with a light mouse movement, and then we wait for two days for each room.
Q: Why do we wait two days? Would it dry?
