ayv been searching and searching the web for a decent exterior rendering using mental ray. unfortunately, interior renderings are only available. so, as a last resort, am asking tips and suggestions on how to improve this rendering. also, this is in meters.
here are the specs for the rendering
a.) wall color - architectural material - paint flat - white
b.) red and yellow accents - architectural material - paint glossy
c.) grass - normal grass bump map
d.) glass - mental ray material - dielectric material
d.1 light persistence - light blue
d.2 index of refraction - 2.0
d.3 outside light persistence - dark blue
d.4 persistence distance - .025 m.
d.5 phong coefficient - 60
a.) spotlight with raytraced shadows, multiplier of 1.0, falloff of 150 with overshoot on.
b.) skylight with multiplier of 0.5
3.) mental ray settings
a.) gi photons - 50000 with radius of .6 m
b.) photons(c&gi) with 100 samples
c.) final gather with 100 samples
d.) global light properties
d.1 energy decay 200000
d.2 decay 2.0
d.3 caustic photons 10000
d.4 gi photons 50000
so here a bunch of my problems...
1.) the glass material is so fake, how to improve it, what mental ray shader to use?
2.) the grass is very fake as well. how to make realistic without using any expensive textures.
also, criticism is highly recommended. i hope this thread will benefit millions of mental ray users especially those who are in the field of architectural visualization. i hope this will answer the mental ray exterior rendering tutorial request.
P.S. special mention to Mr. William Alexander(WDA), Alex Guzman (GI DUDE), Architect John Garcia (Voltaire Ira), Philip De keersmaecker (joske). thank you very much for the replies in my last thread regarding exterior rendering tutorial. thanks!!! (daghan salamat!) <----- how we say thank you in our place!!!!
