Glow settings

Posted by fred henaux on February 5, 2011 at 5:46am in IRender nXt ArielVision 3D Design Studio (Sket

Hi All,

 

Not sure how to explain my question, but here goes!!!

 

When you render a model with no glow settings to any of the materials being used and you render this model with a white floor (Sketchup ground settings), when the model renders, it renders it with the white floor (which is what I'm after), but as soon as you apply a glow setting to one of the materials the ground becomes a different colour! Is there a setting that I can use so I can apply a glow setting and keep my white floor?

 

I hope this makes sense!!!!

 

Thanks

 

Fred

    Another way to retain the self glow without getting the darker ground plane, is to use the Light Balance slider in the Lights  setting window (ratio of ambient to artifical).

    Less ambient the more whiter ground appears, and the more Lights the darker the ground gets.

    Adjust to get the balncs you want, its default is 50

    Hi AL,

     

    Just a precision; you said:

     

    Illuminance makes the material act like a light and it will apply its color to other objects.

     

    Even Self glow will effect other objects if they are reflective.

    ..... cut ......

    • Self Glow - the face glows, but does not illuminate other surfaces. This is the best setting or Neon lights.

     

     Do you mean that illuminance affects both objects and surfaces whereas self glow is supposed to affect objects but not surfaces.

    I don't really understand the difference between both entities.

    Regards,

    Alain

    I can duplicate this by simply setting self glow, to say 30, on the blue rectangle in your sample model.

    I assume to make the glowing rectangle appear to glow, to be brighter, that the engine has to make everything else not as bright. Hence a white surface will be less white, in this case, the ground plane appears darker as I increase the glow on the rectangle.

    To keep a particular surface as bright, white in this case, as it was before adding glow to other surfaces, you can add glow to that surface.  You can add glow to the ground plane on the Options/Background tab, using the Ground Plane "Edit" button.

    I will look at your model and add comments later...

    Hi Al,

     

    I've uploaded a very simple model to show you what I mean!

    Let me know your thoughts?

     

    Thanks

    Can you make a simple mode - say a room with a rectangle on the wall with a glow material on it.

     

    Note: there are two settings on the Glow tab of the Material Wizard - Illuminance and Self Glow

     

    Illuminance makes the material act like a light and it will apply its color to other objects.

     

    Even Self glow will effect other objects if they are reflective.

    Glow Tab

    Defines a material which glows with Self Glow, or acts as a light with Illumination.

    • Illuminance - the faces which contain this texture will act as lights.
    Set the desired Wattage
    • Self Glow - the face glows, but does not illuminate other surfaces. This is the best setting or Neon lights.
    Set the glow percentage - 0 to 100%
