Thanks for the reply.. That Thread was really helpful.. I was in little confusion about flythrough as well as Incremental in LC and Irr. Map.. No thats not the problem of Anti-aliasing.. Once again thank you very much Matt Sir... Greetings from India. ))

I'm a 3d visualizer and recently working on a walk-through.. Here is the scene descreption : 1. There are lot of trees in the scene so I used ITOO Forest Pack for it.. 2. Optimized meshes (other objects) as much as possible.. 3. Less reflective/refraction are used.. 4. No Displacement (Turned Off in render setup too).. 5. Lights : VRaySun for main source light and VRayDome with HDRI for Environment.. 6. Softwares : 3ds max 2012 x64, VRay 2.0, Forest Pack PRO 3.6.2 6. Machine Config. : i7 -3770 CPU @ 3.40GHz, Memory : 16GB, Graphics : NVidia Quadro 600 , OS : Windows 8 PRO x64 So now, problem is I get flickering in tree shadows/darker areas of trees... as well as it takes much time to render (15mins/frame).. I need help for render settings.. Please can you suggest good settings to get out from this?? As well as any suggestion for speed up process of rendering?? Sample Thread :
