To cover a surface with a texture that repeats itself
like a wall pattern, prefer choosing a seamless texture.
To avoid reducing Sweet Home 3D performances, do not import
images with a large resolution (generally, 256x256 pixels images already
give good results). If you have to reduce the resolution of an image,
you should prefer a better JPEG quality over a larger resolution.
Please respect the license of the models that you may
download on these web sites.
