Thank you so much nomeradona! I really found it useful

1.5GB RAM, Core 2 Duo.

Thanks..glad you guys liked it..My boss did a lot of the work designing there. Was just the guy to render and cleanup the work. I Just want to produce cleaner results with regards to the shadow without so much render time. That took like 1 hour and 10 mins to render. I don't think we can afford that.

and how'd you find out that there was light behind the camera?

I can't figure out how to clean up the surfaces if you;ve noticed.

I'm talking about 1 hours plus to render an 800x600 view.. I erased all the other faces that aren't seen. purged everything, not that I think it matters..I'm guessing it's the settings I'm using

Another quick qestion: I changed the secondary bounce to light cache, my first option being quasi monte carlo, My primary bounce is still IR Map..and it made quite a difference. which one is more advisable? and why?

Here it is. I use VRAY for sketchup

having problems with renders: really dirty and noisy. I've tried adjusting the noise threshold and subdivs multipliers, I know this might probably be the solution but I'm guessing someone out there might know how to solve this even better with faster results. Thanks!!!

I've been using vray for sketchup for quite a while now, for the main reason that I'm really too lazy to export it to max and then reapply textures and do everything all over again. The one thing I found in VRAY for Sketchup is that it's really slow. Not so sure it's meant to have VRAY. I've tried experimenting on ways to try to make renders faster but it seems to no avail.

I've had real troubles rendering interiors and get really noisy result at the farthest edges and dirty ones too. I tried increasing shadow subdivs, that makes things slower, adjusting the "subdivs?" in the qmc option again slower. the dirt from the shadow is lessened.

I've come to the conclusion that I should probably go back to max (for very obvious reasons) but our office uses sketchup for all the modelling so you see the dilema. I'm not comparing the two well because of the capabilities of each.

I know I'm doing something wrong with the renders so could someone please lend a helping hand. I really need tips on making renders faster through settings or modelling techniques. thanks!
