Good Morning!
I've just updated to Vray 5 and I've noticed an issue.
I was used to follow this workflow when i had to use a background image to place outside the windows.
It was a simple trick, but it was effective. Now it doesn't work anymore, or at least not as it was working before.
This is my setup:
- Vray Dome with a Vray Sky linked inside and a Vray Sun to illuminate the scene.
- For the background outside the windows I use a simple Plane with a Vray material.
- To let the Vray Sun come through the Background Plane : uncheck "Receive shadows" and "Cast shadows" in the Object properties
- To let the light and the reflections of the Vray Sky come through the Background Plane: uncheck "Visible to GI" and "Visibile to Reflections" in the Vray Properties
Doing this, i was used to see the background i wanted outside the windows, without any interaction of it with the lighting. Like if there wasn't any plane outside.
After updating to Vray 5 I've noticed that the Visible to GI and Visible to Reflection don't work like before.
Same .max file, same options enabled. As you can see the reflections and the lights are blocked by the plane.
Now the Background Plane reflects itslef on the scene objects , blocking the Sky light , even if the options mentioned before are unchecked. Like if it wasn't "perfectly transparent to reflection rays" (as described in Chaos Group Help).
I'm attaching 2 images to help understand the problem.
VRAY 5 : WITHOUT background - More light, more Reflection( white reflection) on the table and on the floor
(in Vray 4 i achieved the same result even with the background outside)
VRAY 5 : WITH BACKGROUND - Less light, less reflection (white reflection) on the table and on the floor
Any advice? Anyone using this method and experienced the same problem?
How do you place background images in your work?
Thanks in Advance.
