IES lights and LC settings

[chow choppe]

hi all

 

i am doing an interior render with vray

i have put a ies based light in the scene

now when i use the primary bounce as LC and secondary as QMC i get the lights as the following image

 

 

but if i use the primary as IR mao and LC as secondary i get perfect lights

 

 

 

the problem is that the second process is slow to render so i want to use the first settings as everything except the IES lights are rendering fine

 

Thanks
