Fantastic how you pinpoint the problems and finds a solution right on the spot, Rob! Thanks!
Unfortunately the breaking/assembling of the splines does mess up the uvs of the model, so I guess the best solution for me is to just keep modeling, uv’ing and texture painting within Animation Master and 3D Painter. The lesson is: splines doesn’t mix well with the outside world!
And as you mention, Ken, with A:M’s rather exotic approach to uv mapping, the steps involved in moving back and forth between different apps, becomes to unfluent for my way of working and my temperament…unfortunately.
One can just hope that some day someone at Pilgway or Pixologic will write an importer/exporter for A:M.
