Problem with vray light blinking

[pradipta]

Hello,

 

I am having some problem while rendering my vray lights for one of my interior projects. I have some pug lights (circular light placed in the ceiling) that continously blinks in the animation. I used the LC and IR method as I do everytime. But this problem is bothring me always. Each and every fraems ome lights are off and some are on and thid just go on throughout the animation. Is there anyway to get a solution to this?

 

Thanks in advance

I am also attaching couple of test frames from the same animation to show I am taking about. You can see the light on the ceiling are going on and off. Those objects are basically geometry and vraylightmaterial applied to them.

thats your anti aliasing.. i'm going to guess that you're using Adaptive Subdivision.. if you are and wish to keep using it, change it from the default of -1, 2, to something positive.. say 0,2 or 1,3.. basically at -1 its doing the first pass of AA at half resolution.. and if the light object is smaller than 1 pixel at that point it has a chance to get missed due to the adaptive nature..

 

you may get a little more help by turning on object outline, or switching to a DMC type.. at the expense of rendertimes

Dave, thank you so much! changing the AAA sampling worked. You saved me. Thanks again!
