Hello Lugnet Trains! Writing answers on your own post might be considered as bad style (like uploading fuzzy megapixel pictures displaying mainly untidy LEGO building tables); but now that fun has returned to Lugnet I dare to do... :-)) If you like (...)

Hello to all train heads, since some life has returned to Lugnet.trains, I may use this opportunity to give a little info on my latest render experience. A few weeks ago I was looking for motion blur effects (to generate more realism in animations (...) (13 years ago, 19-Sep-11, to lugnet.trains, lugnet.cad.ray, FTX)

(...) Yes, there are parallel lights that work just like orthographic cameras. Check the docs. This way you will get uniform lighting on every object in the scene. Mike (13 years ago, 24-Jun-11, to lugnet.cad.ray)

(...) Actually, the sum of *all* your lights should not be too much over <1,1,1> as some parts of the image may be saturated. I usually use 0.5-0.7 for the *brightest* light, and 0.1-0.3 for filler lights. Remember it's easy to modify light (...) (13 years ago, 2-Jun-11, to lugnet.cad.ray)

(...) How bright is "not too bright"? These lights don't obey the r**2 law like real lights do, right? I noticed that if I have several rgb<1,1,1> lights the scene seems "overilluminated" Do you use .5 or so for the not too bright ones? (13 years ago, 2-Jun-11, to lugnet.cad.ray)

(...) I'm 99++% certain that's not the case, given the input data Jeroen was able to recover for me. I think removing reflections would be a lot of work, better to change the properties of the surface to get them not to happen. (13 years ago, 2-Jun-11, to lugnet.cad.ray)
