Not sure where 'this' setting is - but I have a texture that is overall smaller than the 3D model onto which it is being applied.
If this were done in 3DMax, I could easily control the texture/materials applications through the material gizmo, but in Navis' it seems that the tiling is a default and I can't find where/if it's possible to turn it off and have only a single instance of a texture - the outlying model areas are fine in an un-mapped state.
Thanks for the suggestion, JL - unfortunately that 'fit' option won't work in this situation.
What I have is a large topo/terra model which extends a number of scale miles beyond the plant proper data - and the texture map I have at 5Kx5K still falls short of covering the entire 3D model.
I don't have access to the original 3D model data, using a larger texture map crashes my system, and using a map of smaller resolution isn't an option as the renders and ultimate fly-by will be of fairly close positions.
