Self Illumination (emissivness)
-
I have a huge LED screen on the north side of my model. It is always is shadow and always gloomy.
Can you think of any work around to make the texture on LED appear lit up? in life sketchUp without post production or rendering plugins?That will make a difference.
-
Which way does the screen face--is it in shadow from your model or does the screen face north?
(You can set a face not to receive shadows in the entity window, but you can't stop it from having shading because it faces north.)
-
yeah, the face is in the shadow. any one knows a simple plugin to solve the problem or a workaround?
-
If it is in a shadow but facing the sun, you can set it not to receive shadows. Otherwise there is only one way to light a surface, by the sun.
If it is facing north you can make it translucent and hide things behind it except a sloped plane that "reflects" sunlight at the translucent image. The image quality suffers however.

I cant believe SketchUP still doesn't have emissivness control after all these years.

emissivness
Can you list the other modeling apps that have emissivness? -
shadeless could be useful for screens and low poly trees (crossed planes). Anything where you don't want shadow effects but just a flat unshaded plane. Would that be hard to implement? Blender has it and my guess would be: any 3d modelling-rendering program.
-
Try right clicking on the object and open the Entity info window.
At the bottom there is a checkbox for receive shadows.
Uncheck it. -
That works well if the object is in shadow and facing sun. However if it is not facing sun, there is no hope (
-
Artlantis will produce "emissive" screens.

In the early days of SketchUp, before there were any renderers at all, one method I used for depicting a more ambient light in an interior was to go to the Shadows control (now part of the trays setup) and reverse the position of the sliders. Move the Light one way down and the Dark one up. As long as you don't slide them clear to the end (which is effectively the same as turning shadows off) you'll still have shadows, but they'll be far more muted.
