Hello On this couple of videos I give you an overview about the new feature for second life (at time of this video in beta viewer) for create materials with normal maps and specular maps in second life. the first video focus on what are materials, how can change the workflow and how create materials.
The second video is about how you can create you normal maps form a diffuse map , with a free tool “Knald” , and how you can create materials (all the maps ) for second life
PD: I hope my English makes you laugh a little, but do not despair ;). Laughter is good !
