Light portal not working in latest version

[andre_sousa]

Hi guys, need some help overhere.
I've just installed the latest 5.00 version and light portal is not available.
Used to create a rectangle light, double it and check light portal simple, but now, the option is not available.
In other hand I can copy the light portal from other file and paste it (not a solution though).
Can anyone help in this??
Attached 2 pics, before and after update.

Thanks in advance..

Hi andre_sousa

The Portal Light option in V-Ray Rectangle light is now a legacy option and is no longer exposed in the UI. Rectangle lights in files saved with previous V-Ray versions and this option enabled will still have it available. Regardless, for best performance consider disabling it and using the Adaptive Dome Light option instead.

Hi andre_sousa,

Here's a video that more or less explains what the current recommended workflow is:

The light portal, was extremely flexible.., to direct natural light to a particular part of your object that needed more light for any reason, this is really powerful and now the adaptive light can render as fast as it can.., but wont give this amazing feature..,

Hi all.
I think this is a very important option. And I would really ask to return it to the interface.
Adaptive Dome Light didn't help me render clean in a large room with curtains and tulle.

Maybe my Ruby script will help you
Select the lamp and run the script in the console.

It is more convenient than copying a portal from old files

selection = Sketchup.active_model.selection
comp = selection.find{|sel| sel.kind_of? Sketchup::ComponentInstance}
comp_name = '/' + comp.definition.name
option = VRay::LiveScene.active.find{|plugin|plugin.type != nil && plugin.type == "light" && plugin.name == comp_name }
option[:lightPortal] = 1
VRay.refresh_ui

I also prefer the Portal Light effect, I think it should be kept, as it happens in V-Ray for 3DS Max.

Thank you for script, works perfectly
