Do not understand lights!

[pnavarra]

Hi,
I'm trying to do the tuto of the glass.
link here http://www.asgvis.com/index.php?opti...d=34&Itemid=55
I can see the reflection on an omni light on the first metal ball.
I can see also shadows.

Questions :
Is there more than this omni light in this scene?
Is it possible to desactivate Sketchup default light ?

Re: Do not understand lights!

Deactivate the sketchup light by unchecking Default Lights in the Global Switches rollout. In that scene there is a Vray Sun, but no other lights. The reflection in the metal ball is from the Vray sun. Omni lights will not generate any reflections like the ones in the mirror ball.

Excellent, thx dolomar. ;D
Here is my render.
I've got questions :
Is it possible to diffuse shadows?
The oritentation of the shadow seems to be the same as the SU light settings.
As you can see, I've unchecked all options and I've got shadows...
Do not understand... :-\

Re: Do not understand lights!

Having the V-Ray Sun active works within the GI Environment settings. Therefore, there are no lights in the scene...only GI. The V-Ray sun takes its position from the sketchup sun even if the sketch up sun is not active. Having the V-Ray sun automatically deactivates the Sketch-up sun. When you say diffuse shadows I assume you mean slightly blurry edges, and currently i don't believe there's a way to do that with the v-ray sun.

I think you can disable the sun's shadows as well through the SkyTexture's UI. If you go to the global options ->Environment tab and edit the GI/BG texture I think there is a "Enable Shadows" checkbox.
