Hi all, i have a problem with white / grey materials either glowing bright or getting black depending on the sun's position. I have experimented with spec rgb and values in the shader , the spec map, dif map alpha channel, i copy settings from 397 materials , duplicate them as they are (with 3dsimed) and mysteriously they still misbehave in my scenes while they look fine in 397 tracks, eg. bump specular map t1 for billboard adds. a. Below is a striking example of this, the flags use bump specular map t1 , in the pic the 3 bright ones are perfect from noon until sunset but in the morning they are black, so i realize i need to reverse the faces but then they get black in the noon. b. Also in red circles these white lines get brighter when they re further away (they use alpha transparency and they re seperate from the road object), how can i fix that? Note that th dif map in all these cases is dark grey, it might be greenish grey or something else but in day light it's completely overridden and just glows bright and white. Should i use gravel trap shader for everything , mean i dont need all these uv channels usually. Help pls!
