Hi, guys.
After my investigation, I found the wrong settings of various specular materials! Because its have the lack of dispersion and the reflection isn't realistic. I pity...
For real-life, the any specular material must have:
- reflection 1.0
- dispersion
NO EXIST any specular material non-dispersion in real-life. Lower dispersive of liquid material is likely liquid helium (He) = abbe number of 220 (= dispersion coefficient of 0.0015 but sorry no sure - disp. coeff.).
Therefore, try to correct wrong settings in LiveDB.
