In order to be successfully unwrapped, a 3D mesh must have only 2-manifold edges, which means that there may never be more than two faces connected to a single edge (otherwise, generating a non-overlapping 2D UV layout would be impossible). Victor is a simple 3D bust of a character, a manifold 3D mesh that has three boundary loops: a large one at the neck, and two smaller ones for the holes that were left for the eyes. To get started with the unwrapping functionality of RapidCompact CLI, we will use a simple example mesh of Victor, which you can download here.
Resolution at which packing will be computed Threshold (degrees) for cutting sharp edgesĭistance in pixels packing will keep at reference packing resolution Threshold (degrees) for overall curvature of 3D charts Limits max number primitives in any UV chart In addition the RapidCompact CLI comes also with settings for other important UV- related topics such as segmentation and packing: Some unwrapping methods are guaranteed to never produce overlaps, and in for those methods this setting will have no practical effect. As we will see in the following, this setting only has a practical effect if the unwrapping method in use potentially produces overlaps. It depends on your unwrapping task whether you want this or not. The second setting, unwrapping:cutOverlappingPieces, is a flag that specifies if overlapping pieces should be cut in order to resolve UV overlaps, or not.
The first setting, unwrapping:method, can be used to specify which method should be used for unwrapping.Īs we will see later, choosing the right method for your unwrapping task is very important, as it has a strong impact on the result,Īs well as on the duration of the unwrapping process.
