Vray Warning!!

Hello to all CGP masters and members!....mabuhay po kayong lahat!

Just a little problem I encountered with vray, maybe some of you encountered this also and solved it!!! might as well share some solutions. The problem is, when I render a particular scene in vray it gives me "warning: Material returned overbright or invalid color" & "warning: Invalid light cache sample(s)".....

all of my materials and lights are vray and never used raytraced, I have one omni but with vrayshadow used.

hope somebody had solved this issue.....thanks and regards

i got the same problem with that sir, sometimes it happens to me, what ive do is just to restart my machine and thats it, nawawala yung warning.

merong isang object yan sir na di naka vray mat.... try to right click on any viewport then convert the scene to vray.
