Hi all, I am trying to light map my level using the external lightmapping tool. Everything works as expected, however some objects that I have used the combine children script on only render black when the level loads. If I remove the script all the light mapped information displays correctly but my draw calls goes up a lot (500+ draw calls). Ideally I would like to combine these objects as they are all identical and packed into a close area. I feel that I may have overlooked something. The shader I am using on the combined objects is the ExternalLightMappingTool/LightMappedDiffuse. Has anyone else encountered this issue? :?
