Artificial light questions, total newbie

Post by swissdude »

hi helpers!

so i have done my first playing and am very happy with this program.

my main problem is making a artificial light. i have V4 so if i understand i dont have to make a lightsource material in SKP and can go direct to the render.

i mark the material as a light in the material editor , do what i can with the settings but never get any light. i also cant check the box under illumination, artificial light. its always grey?

here is what i want, i have a booth and under the channel on the wall we have LED`s - so i want to light up the back wall link i have done now with a texture.

any easy steps to follow?

also i always have to set the color of the sunlight to 100% white, is there i way i can save this preset?

thanks, lots more questions to follow :)

patrick

Hi,

You do need to set a material for your light in Sketchup, any material will do as long as it is not the "default" material.

In Raylectron with the Material editor open, right click on your light (in your example, right click on the pink) and it will show in the editor. From the dropdown list "Convert this material", select "Emitter/Light" and at this point, you can turn on the lights in the "Illumination" settings. If you did this correctly, you'll see the number of lights is displayed in the status bar, something like "1/1 lights(s)".

The front face of your light is the direction of the light beam. So if you want the pink light to shine down, make sure the front face is pointing down, the back face never emit light.

I would suggest to use "Real" shadows in the Illumination settings to make sure you can see the light because Ambient or Eye shadows may be too bright.

Another suggestion is to close off your room and either create some section cuts in Sketchup or use the XRay in Raylectron to render through your walls. This is the most accurate way to illuminate your room or else your light will not bounce in the walls since it will go into empty space.
