Hi all, i have a Vray dome light in my scene, but client dont like the hdri image as background, so i create a plane outside of my window and attached a background image(jpeg) given by my client, but when i render the scene, i discover that the background plane has block the vraydome light, what should i do avoid this?
i am using 3ds max 2014 + vray 2.40.04
anyone help??
Make the plane to not cast shadows, and also make it invisible to GI?
Best regards,
Vlado
I have make the plane (in object properties, i untick receive shadows, cast shadows.), (in vrayobject properties, i untick generate gi, receive gi and visible gi)
is there anything i have miss out?
That seems about right. Can you post a scene with just the plane, some geometry and the dome light to check what may be wrong?
Best regards,
Vlado
can, mr vlador, where should i post?
Hi Mr Vlado, i have send the file to vlado@chaosgroup.com, please check, thank you.
Hi Jackie,
I’ve rendered the scene that you sent to Vlado with the BG object (background plane) and without it but didn’t find any difference in the lighting. Can you send me a simple scene that reproduces the problem at peter.matanov@chaosgroup.com? Because the one you sent is missing textures so I had to override the textured materials and the HDRI that was in the Dome light.
Peter, try rendering with V-Ray 2.40; it worked fine for me in V-Ray 3 too.
Best regards,
Vlado
I exclude from dome light and my outside window plane is a V-Ray light material
Tried both 3.1 and 2.40.04 - the renders are identical with and without the BG plane.
Isn’t that just reflection differences?
Best regards,
Vlado
Vlado, sorry it was my fault, it only the reflection difference.
Thank you for your help.
Finally i done with two rendering and match it in photoshop, client happy with the final result.
