why lighting in blender render engine is not good as other engines what erver you do its still agly
Because it is based on a far more primitive lighting engine. BI does not take reflected light into consideration.
Maybe that’s why lighting – in CG and in real life – is an art that some people specialize in exclusively.
Go volunteer at a local theater sometime and help them hang and set the lights. Take a long, hard look at the “lighting design” that they’re working from.
