after light cache screen turns black then renders

is there a some interpolated material in the scene causing this? am using the new method not IR, this was the case before with materials if so then how to check which material has this setting without doing it one by one

You can use VMC to disable interpolation on everything : http://www.scriptspot.com/3ds-max/sc...terial-control

Thanks! i forgot about this fully, i actually just found the material myself, was actually interpolation on one material, i usually set the vray messages dialogue to only popup on errors only so changed this to always and saw the material causing it, thanks!
