Loading a 3ds file that was exported from Cinema4d I am receiving the following error:

One or more uv buffers were invalid (269). Default uv’s were applied to these buffers.

Could I get some more detail on this error message? So far my google-foo has failed.

It means that the file either lacks, or have incorrect (e.g. wrong number of ) UV texture coordinates for one or several of it’s objects. Make sure that you export UV coordinates along with your file from Cinema4D, if you intend to texture it.

If you don’t intend to texture it, but use just single-color materials (shaded or not) you can just ignore this warning.
