hi all,
my night scene needs 2:20h for rendering i use maya own bump nodes and some mental ray shader. I know that area lights with light shapes use to slow down my render time but when i use a dgs shader with a mr bump node pluged in specular he speeds up.
The problem is i dont know how to use the mr shader to reach the quality of my maya shader.
here is my scene for the wet ground with maya own shader under mr render:

my shader network for the ground:

The mr dgs try:

and the shader network:

my scenesettings:
Light settings:
1 direct light for the moon cast shadows on the ground "ray trace shadow"
6 direct lights for illuminating the scene with blue moon light
3 Area Light "mr light shape / ray trace shadow"
Rendersettings:
HD720
AA 0/2 Box 1 1
contrast 0.01 0.01 0.01
raytracing
refr: 4
refl: 4
max trace 4
All textures are baked in .map format // 400-500MB
Need some help to tweak my shader or my settings for the scene....thx for help :)
