gamecreator Posted October 4, 2013 Share Posted October 4, 2013 There are definitely paid programs out there that do this for you. There are probably free ones too. Quote Link to comment Share on other sites More sharing options...
Andy Gilbert Posted October 4, 2013 Share Posted October 4, 2013 There are free and there are paid but to be honest if your thinking down them lines you will be disappointed. I've found very few apps develop decent spec maps from diffuse maps. Spec maps are more important that normal maps. Normal maps give some depth but a spec map tells us what material it. And despite if the diffuse is bumpy, smooth or flat the 'spec making software' still doesn't know what material it is or what you want it to be. So if your wanting to create spec maps from diffuse then I recommend using any decent photo app, or downloading gimp open the diffuse image, convert to greyscale and then open the curves filter and playing with them to get the desired result.

tjheldna Posted October 5, 2013 Share Posted October 5, 2013 Crazy Bump makes quite nice spec maps too, not free though. It was worth it IMO. Quote Link to comment Share on other sites More sharing options...
paramecij Posted October 5, 2013 Share Posted October 5, 2013 The following also applies to auto-generated specular maps (maybe even more so, as pointed out by Andy). A brief mini-tut on why you should generate height maps for your textures rather than throw the diffuse into crazybump. Written in response to seeing the latter technique used more and more by new artists who think it's a valid way to get a good normal map. http://www.farfarer.com/resources.htm -edit: forgot to also include this tut: Creating a Specular Map for Quake 4 http://www.iddevnet.com/quake4/ArtReference_SpecularMaps 2 Quote Link to comment Share on other sites More sharing options...
