Well now you have. This is JK3 not ioquake3. Also be aware these are not 'proper' external lightmaps as JK3 doesn't support them, its a shader workaround as described in the tutorial link I posted above. The only game I know of around JKA era which did was ETQW. The options if you are able: - Implement internal high-res lightmaps (? comptibility issues) - Implement external high-res lightmap support - Fix the patch only/nodlight issue caused by current workaround implementation of external lightmaps (See tutorial link earlier) - Dynamic lighting system. EDIT: Here's the tutorial link for the workaround again (only works on patches with nodlight surfaceparm) Was written for Smokin guns where presumably, there is no issue, http://sgq3-mapping.blogspot.co.uk/2009/01/using-hi-resolution-external-lightmap.html Here is the wiki description of this workaround - http://openarena.wikia.com/wiki/High_resolution_lightmaps
