Puybaret Hello! I wonder if after importing furniture for a Sweet Home3D, I delete the original file, or need to keep them in a folder outside the program? Before they disappeared when the program excluded the file. After the rendering problem be solved, they always are in the program even if I delete the source file. I'm afraid to delete all, and they disappear from the program. I tried and did not find the answer. Thanks. Hug. I use a translator.
