This option will take all groups of the OBJ and combine them into a single mesh.

Sometimes you will want to animate with a single mesh within EI but you only have a separated figure. When you check this option, OBJ2FACT will combine all original OBJ groups and their UV spaces to a single FACT group.

If you have the "Seperate by Material" option checked, the box will be renamed "Join Materials". In this case all polygons that have the same material will be combined into one group for each material within the FACT.

Note: If the UV-coordinates of different objects in the source OBJ lay in the same space, they will also lie in the same space of the converted FACT file. This will cause problems during texturing.
