Hello everyone, thank you in advance the help I can get and sorry for my English.

I'm working on a 3D model of an apartment and when something fixed perspectives I have no problem

When I try to do the animation, I first make the process of generate the light cache and irradiance map, but to render I get black spots on the wall. The project is done in 3DS Max 2012 and Vray 2.00. SolidRocks try and do it with me and the same thing happens. Please your help .... Attached images with the settings of vray.

Looking at the images the first thing that comes to mind is the irradiance map settings aren't right, and on closer inspection they aren't that great.

 

Your Hemispheric Subdivs setting is way too low, it probably should be a minimum of 40, ideally 50. If this increases your render time too much, you could probably get away with having a max rat of -1, possibly even -2 (but you may need to crank up the subdivs a little more).

 

You also seem to have some very strange, almost arbitrary numbers in a lot of the settings - the colour, normal and distance thresholds for example... And your DMC sampler is set to 171 minimum samples(?!), along with many other settings.

 

[edit] I'd advise you don't use things like Solidrocks until you know what the actual settings do. The settings you've got seem quite nonsensical to me.

Make sure you have enough light sources in your room as well. Just using outside light to illuminate your interior isn't going to give you nearly enough light information to sample from, provided you are using the proper sampling as Chris has pointed out. The only samples from the outside are allowed through the open door, even if you are using the nuclear sun.

 

Your settings are all over the place. Did you use a random number generator?
