_Sunlight of the toolbar official not supported by McNeel?

[Micha_cg]

Hi,

looks like the chaosgroup team should talk with McNeel team about the _sunlight feature. Not that we miss it in the future:

I'm not sure I completely understand, I don't see the problem.

I run in the problem because I wanted to create a Vray sun light and type in sun and I didn't know about the difference between _sun and _sunlight, because there was only one auto completed command. I set the sun options and than .. there was no OK button. I leave the UI and looked at the Vray toolbar ... and later my render shows me two shadows, and I don't understand why.

But for me it's no problem anymore too, but my impression is, that other user was and will fall in this pitfall too, the autocomplete should be available.

I had the same problem. It disappeared when i copied everything except the existing sunlights into an new rhino5 template.
I guess something goes wrong with the existing rhino4 sunlight and rhino5 sunlight.. you cant get rid of the old rhino4 sunlight.
it also shows the "old" rhino 4 sun under the environment\GI (skylight)\TexSky. Even when you delete the "sun (arrow)" in your model.

Hi Micha and Thornado
We basically have three way to create a sun system.
1. "Sun" command - this is what we called the Rhino Document sun. It doesn't have a physical representation in the viewport and you can control its position with the sun option windows. This windows save the sun position, so if you want to change the position, time, or location, you can do it through it. You need to select "Rhino document Sun" in the "Environment" "texSky"
2. The sun that you can make using the V-Ray Sun icon - Rhino 5 doesn't support "_sunlight", but we are going to support it. The V-Ray sun icon could make a physical sun representation in the viewport, making easy to control their location in the viewport. I recommend you use this method to created the sun. At this moment we have some issue with the Rhino document sun.
3. You can create a Direct light and convert that light to a sun using the command "_visMakeSunLight". At the moment we have issue with old scene (scenes that was made using VFR 1.05.29) that have a sun that was made using this method. The light seem to go back to a direct light and you can not convert the old direct light to a sun using the "_visMakeSunLight" command. If you created a direct light in VFR 1.5, you should not have any issue.

Any combination of those three method will produce extra shadow. SO if you have a sun made by the V-Ray icon and the Rhino document sun, you will have two light source in your scene, due two shadows. All the method have a way to enable or disable the light. It is just a check box.

Hi Thornado

In VFR 1.05.29 we have a sun option that we called "Default". That was the default rhino light that was always attached to the camera. In the old VFR 1.5 beta build we didn't have any way to remove that light and it was always present in your render, producing double sun. We fix that issue in the latest VFR 1.5 beta build.
