Hmm, now that you say Rawalanche, I checked my glass material and it was not set up correctly. It seems I did not think it through, just blindly applied some values I found for glass somewhere. Reflectivity was at 0.7, refraction at 1, Fresnel IOR was 1.98 and IOR at 1.52. I corrected it now. I had a feeling something is not quite right with the glass, and remembered vaguely that the IOR should be lower, but it did not seem to be an issue at the time and then forgot about it. :)
Thanks for the useful input about the scratched surface, I would have probably gone in the same direction with the material setup eventually but it is always good when experienced people confirm that I'm going in the right direction.
Hehe, maybe my next programming project will be a physically based stupid kid simulator plugin :)))
I will need to have some graffiti tags on these glass panels too, so I thought I would set this up in a similar way as the scratches. One mostly white map with black "writing" on it connected to Refraction Color and then connect the same map to Diffuse, Refl. Color and Refl. Gloss too, just with different color correction filters to adjust the final look.
It seems I can achieve the looks I want with this method but is this the best way to do it?
Thanks PROH, the model was made entirely in Max. Sometimes I find Max to be frustrating after Rhino when I want to be totally accurate, but I decided to stick with it so I could learn.
I have some information about the dimensions of these trains and have some drawings of them. As it turned out, the data I have is not 100% accurate. The local transport company trusted the dimensions on the drawings but when they built a station based on these drawings they found that the whole train is a few meters longer than what they expected :D So there is a lot of measuring involved in the process when the security is not watching and a lot of educated guesses on my part which can be especially hard when I can't even see the real subway wagon myself, only rely on measurements and pictures taken by others.
