    Many thanks for your suggestions, comments and critics, they are all very constructive and usefull as allways!

    I ve use one light ligth for each can-light since the poupose of this render was to understand how should I illuminate the space, and to see how it can work at night.

    It was done with irradiance map only since it respects the IES information, unlike photon map. Also I have not enough memory that could handle so many lights with a good quality for each too.

    I ve 105 lights in this space, and this can turn this render into a hell, the irradiance map and AA tooked 8 hours each, at 3200x1600
    It was not my intention to make a final image, but only a small test in order to see how long it could take.

    João I think the stone you are asking for is called "Vidraço" wich is a sand stone.

    A lot of work need to be done yet, and my intention is to place a Landmark near the camara at the right side of the image, but probably I will turn off the lights too, and do a day scene instead.

    Trixion, your suggestion is great and I ve try that, but I m sure you can imagine why I give up from this...

    I ve use Adaptative subdivision -1,2 with treshold 0.1 and randomize checked.

    First diffuse bounces

    Multiplier 1.0

    For irradiance map -3,0 at 960x480
    Clr tresh. 0.25
    Nrm Tresh. 0.3
    Dist. Tresh 0.2

    HSph. subdivs. 50
    interpolation samples 20

    Secondary Bounces

    Multiplier 0.7

    Subdivisions 1
    Depth 3

    Exponential color mapping, with dark multiplier at 2.5

    Thanks all,

    Gonçalo

      Great work!

      Perhaps related to the topic, do you create/use the IES lights in MAX
      or do you get them from ERCO?

      I have tried to use IES lights and my inexperience with them has led to
      alot of poor results. I have tried making an IES light then importing the
      IES data from ERCO but it always acts really odd and the icon looks like
      a clam shell like shape, can never see which way it is pointing.

      Any tips, sorry if it is a bit off the direct topic but you really have it under
      control.

        I ve got them from ERCO site, and the advantage is that the light feature cames with the IES data, so its easier to understand what we are doing.
        They also have information about each light, where and how you should apply them too.

        Its a great resourse imo

              Yes Marc, I didnt expect that it could take so long...
              I was doing some rendering tests without reflections and with a QMC noise treshold at 0.1, and each test tooked no more than 12 minuts, so I ve change that value back to normal, turn on reflections and bum

                About the reflections on the windows, I think it's normal there aren't any. If you would be inside and look to the dark outside, then you would see reflections, but not the other way around. Maybe if there would be some lamp posts outside the building, they would show up in the windows, buther other non-light emetting objects will not be visible in this view.


                In your 12min test, was the min max settings also the same as in final image? Seems a bit drastic increase by only changing reflections and QMC noise!

                  Yes, I have use the same settings for this image... And I agree that was a very drastic increase, I would expect maybe something like 1-2 hours, not 8

                    hmmm...that's interesting....I think you're right, I just thought about it when I saw goncalo's rendering...I'll have to pay attention at night at that ....
                    food for thought, I guess

                      I am affaid you won't fill it with the Land Rovers...

                          Hi Fermí,

                          I will not fill the image with landrovers, I m more interested about the light itself right now...

                          I think the best located one is this http://www.portugalvirtual.pt/_lodgi...ril/hotelbaia/

                          Another ones here too

                            Gonçalo, if i using the luminaire from erco (not IES data), is it affects the vray glass( vray shadow)? cause i only see the dimmer and color parameter.

                              The Erco Light Object comes as an assembly. U Can open them for edit and change what u want. i find that after i insert one of them and change the shadow to VRayShadow, all the rest r inserted with VRayShadow also
                              ( i don't know how this is... maybe some MAX default shadow assignment or somthing )

                              the Assembly menu is on by default in VIZ but in MAX 5.X u need to add it via the Menu customization... just add it into the main menu group.

                              Regards,
