zeno Posted July 30, 2017 Share Posted July 30, 2017 Hi, I'm trying to create a light coming from the outside, but i have some problems. First of all, i don't understand why a spot light cross the slab even though the option "create shadow" has activated on the OIP Quote Link to comment
markdd Posted July 30, 2017 Share Posted July 30, 2017 In the renderworks background you will need to check receive shadows in the lit fog section 1 Quote Link to comment

zoomer Posted July 30, 2017 Share Posted July 30, 2017 Is there a way to fade out the sharp corners of the beam with distance, like soft shadows for the light source ? 2 Quote Link to comment
zeno Posted July 30, 2017 Author Share Posted July 30, 2017 I'm trying to set different setting I can not understand why the light that comes to the bottom wall does not becomes red or orange (like a evening light). I can not change the color of sunlight. Quote Link to comment
zeno Posted July 30, 2017 Author Share Posted July 30, 2017 Ok.. just the fill color.... Quote Link to comment
zoomer Posted July 31, 2017 Share Posted July 31, 2017 Do you use a heliodon with a physical sky ? That should have a suitable tint at these angles. Remember I had once a purple sun light. Took a while until I realized it was the fill color, which I always have activated for 3D + set by class + I apply colors for lights and cameras that I do not use anywhere else. Would prefer color settings in lights itself. 1 Quote Link to comment
rDesign Posted July 31, 2017 Share Posted July 31, 2017 In addition to the 'Physical Sky' setting on the Heliodon as @zoomernoted, there is also a check box for 'Warm Colors'. Quote Link to comment
markdd Posted July 31, 2017 Share Posted July 31, 2017 No setting for lit fog though. Is this just ON by default and renders as such if the background has lit fog enabled? Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted July 31, 2017 Vectorworks, Inc Employee Share Posted July 31, 2017 Unfortunately, Directional lights and Heliodons (which are basically a special Directional light) can not have Lit Fog. This makes it very difficult to create "God Rays" coming from windows and skylights. You can do it with a Spot light placed very far away (so that the rays seem parallel rather than coming from a point just outside the window) but this is limiting since you can't make it interact with a physical sky like you can a Heliodon. It does allow direct control of the color however. I am not sure if this is a limitation of the Lit Fog tech we use or if it was just disabled because of how long renders trying to create lit fog infinitely far away from the scene would take. 1 Quote Link to comment
markdd Posted July 31, 2017 Share Posted July 31, 2017 That's interesting. There was a really impressive render posted on here by@Luis M Ruizwhich showed a library in a house with lit fog enabled. It was atmospheric because you could see the beams of light from outside coming in through the window. But I could see that he had made it with a non directional light object as you could see the beam outside the window as well. A really interesting development of a glass texture might be that only light passing through a certain texture is rendered with lit fog, as in light entering a smoke-filled room from the outside. Maybe a "lit fog" section to the Indirect lighting options that already make up a texture. That would be very cool. Quote Link to comment

Add this to the Vectorworks Paradox list (2 or 3 tools that almost get the job done). 1 Quote Link to comment
