[FONT=Times New Roman] I would like to create a dynamic material (more specifically, hair on alpha cards) which iridesces between the tones of dark blue, dark purple and black-- switching colours as a reaction to light in a similar manner to corvine feathers. How would I be able to implement this?
Also, many tutorials have recently said that every mesh needs to be imported with its respective lightmap in order to receive proper lighting. How much space does each UV lightmap take up, and should it be a cause for concern in terms of project size? If so, is there a way to feed a UV lightmap to the given object using a RGB or Alpha channel within a material instance?
Thanks in advance
