About the scenario

This scenario executes a typical chain of algorithms, to transform a CAD model (made of CAD surfaces) or a Tessellated model (made of meshes) into optimized meshes, ready to be exported to a game engine or any staging tool (through FBX export for example).

About available options

Typically with a Tessellated model (mesh):

• If the UV layouts are already good on both channels (already UV-ed in STUDIO, or inherited from another software for example), uncheck both options to preserve them
• If there is no UV at all on the meshes, UVs will be automatically created on both Channels 0 & 1, by projection (algo GenerateUVonAABB, size=100)
• Check OVERRIDE EXISTING UVs option to replace potentially existing UVs on both Channels 0 & 1 by new ones, created by projection (algo GenerateUVonAABB, size=100)
• Check REPACK UVs option to repack altogether the UVs on Channel 1 of the whole scene (on the selection of all meshes in the scene)

Typically with a CAD model:

• Whatever the chosen parameters, UVs for Channel 0 will be automatically created, by projection (algo GenerateUVonAABB, size=100), and UVs for the Channel 1 will be automatically created at tessellation phase (based on CAD faces)
• Checking OVERRIDE EXISTING UVs option is irrelevent: it will not impact UVs
• Check REPACK UVs option will repack altogether the UVs on Channel 1 of the whole scene
