European Style Apartment - inner Lighting with DAZ 4.24 ?? (solved)

Hi,

On the product "European Style Apartment" there is a preset for the night lighting.
But what ever I try, I can't get the lamps emitting light.

I found surface areas which are named ..._Emis_...  They do have emission settings. But there is no light emission while rendering with iRay.
And there are no parts of the mesh related to these surfaces.

I'm rendering with iRay. The only light visible is the PNTR_Emis_RED in the "EuroApt - Kitchen" -> "KitchenMain".
So why isn't the rest of the lights working for iRay with DAZ 4.24?

    I checked and found the issue you described: There are surfaces with emission properties, but when checking these in the geometry editor (switched everything off but the emis stuff) there just was no visible geometry.
    I tried the following, which worked:

    1. In the scene overview I filtered for Lamp.
    2. Select a lamp and switch to surface settings
    3. Depending on the lamp there is some surface with glass in the name
    4. Apply an emission shader to this surface

    The appartment uses the old ghost lights, and a change in Iray made these light not really work.

    You can try increasing emission power, by doubling the number of digits, but the results will be try and error.

    My suggestion is to add your own lights.

    You can fidle with the setting and making the bulb shine, but it is not so easy to do.

    Made a quick trial in the living room, but you can see it need more tweeking.

    You need to enable the lights in the Paramters tab.

    Parameters>Pose controls>Light on/off.

    This need to be done on every light fixture.

     

    Edit:

    Further testing, it's a combo of the lights being disabled and the creator using ghost lights by applying a black texture to the "Lamp ball" surface.

    If you remove that texture, they'll work, but you'll have a weird object around your fixtures.

    As felis said, gonna have to redo all the lighting on this one.

    Filter Lamp in Scene pane firstly. Then select the lamps that you need, turn their Light On/Off to On in Parameters pane.

    With a Lamp selected, in Surfaces pane, choose LightEmis surface, set its Luminance to 2000 ~ 40000 as needed.

    Ah OK.

    thank you crosswind. The switch in the pose control works. But gives a weird shine on the ceiling.

    I by myself used the proved method of using the most outer (glass-)surface as the emissive surface. So I created my own material settings for on/off of each light. This provides a more realistic light distribution.

    Thank you to all.

    I remember Rougey provided a fix for this, a script that sets the lighting exactly like it was before the iray changes, you just need to doubleclick it with the scene opened. Search the forums for "European Style Apartment" and you will find it. I'd give you a link, but the forum search seems to be broken atm.
