The following describes known texture extraction limitations that have been fixed in the Mudbox 2009 - Service Pack 1 release.
Multiple source models not recognized for texture extraction
In Mudbox version 1.0.7 it was possible to extract a texture map from multiple source models and the resulting map appear as if it was from one model. This feature did not work properly in Mudbox 2009 and has been fixed in Mudbox 2009 - Service Pack 1.
Artifacts in extracted displacement maps
A number of limitations related to the appearance of visual artifacts in extracted displacement maps have been fixed.
Base subdivision level not updated prior to texture extraction
Mudbox did not automatically update the base subdivision level when edits were made at higher subdivision levels. As a result, the edits were not taken into account for a texture extraction unless the user first stepped down to the base subdivision level prior to the extraction. This has been fixed.
