I didn’t try much with interpolate glossy reflections, don’t understand it very well. I notice it adds extra prepasses, are they completely seperate from the irradiance calculation passes? Also, in my little tests the glossy reflections never looked good with interpolate ON.
What are your settings for the interpolate glossy?
thanks
min rate -3 max 0
interp is just a way of speeding up the glossy reflections. i raises the glossy samples to 50
Flipside, if you dont like the inteplotion look try at least with very low subdivisions like 3 until 6 should be quite good for almost all pourposes. The default 50 is good for interpolations.

i opened a window so to speak. you had a window there so hey!! i used it 
can’t see your image elf!
goncalo, I’m testing things right now, one thing I don’t understand already. Scene using geosphere with glossy reflections on:
test1
glossiness=0.7
subdivs=20
interpolate=yes
min=-3
max=0
clr=0.25
nrm=0.4
interpolation samples=20
rendertime=58sec
test2
glossiness=0.7
subdivs=20
interpolate=yes
min=-3
max=0
clr=0.25
nrm=0.4
interpolation samples=1
rendertime=58sec!!!
almost no visual difference!
What is this interpolation samples value???
I thought that it was a replacement for the subdivs from the moment you set interpolate on, but this is not the case (changing subdivs does a lot even with interpolate on)
image took a little long to upload
the subdivisions means quality on reflections like hemisphere subd. on the irradiance map. with high subdivisions you will have a high detailed reflection, and 50 is the amount of subdivisions to get a good reflection using the interpolation method.
The interpolation samples is a kind of blur applied to the subdivisiond amount, a little like Filtering on radiosity engines.

:?: I am sorry to ask,how can I make the VRay logo in the rendering image?
use the demo 
I am sorry ,where is it? :o
You can find the demo at www.vrayrender.com

Thank you!I will try it.
Flipside,
I did a small test last night with your scene using photon map and a Vraylight instead of a omni, this is the result.
I can post the settings later
Gonçalo
Hey looks good!
Settings would be interesting indeed. I especially like the fact that the light isn’t burnt on the nearbye wall.
Thanks,
flipside
Goncalo, do you mind posting the scene w photon maps?
hey I like your images, but I think they render so fast because there’s no detail in the GI. Everything looks like it’s floating. With min/max of -5,-3 that’s no wonder…
Goncalo’s pic is better, regarding to the floating but it’s not like it’s should be.
The irradiance map settings used on this image were -4,-1 not -5,-3 and if you really need a very hight detail GI, go to presets and chose “Very high”, and wait a little more. This works fine for 600x600, then you can save the Irradiance map and reuse it from file for the final image or if you dont want to do that, each time you double the image size you can increase the irradiance map settings. The pastel look is caused by the use of store with irradiance map options, again uncheck this option and wait a little more, the image becames nicer!
But of course this is not rule, this is how I use to do, you are free to use the settings you want and the render time need to get best results you can.

I think he was talking to Da_elf
Yes indeed, to da-elf
In your image (goncalo) it looks better (probably due to the better settings). Can I open viz files in max? i didn’t try to check your file yet.
