Vray environment background won't save with image

[palosanto]

Hi,

 

I'm using vray for Rhino but it probably doesn't matter what the vray platform is.

I have a scene with an environment background image set in the Environment background slot of the option editor tab.

The model renders and displays fine in the VFB.

But whenever I save as png, I get a transparent bacground instead of the background image.

If I save as jpg, the image is complete.

Where the heck did the background go ? I like the png format but in this case I don't want transparency. I don't see a choice for that.

 

If I use a dome light instead and place the environment image there, I have no problem saving as png. But if I use the environment background option I get this problem.

What am I missing ?

I use 3ds max, and when i save .png files i get a popup box with some settings i can choose before saving. One of them is the option to save the .png with an alpha channel - the thing that is most likely causing your problems. I am not sure if you get that popup box in rhino, but i guess you should. Note: Sometimes saving with a transparent sky may make it easier to insert another sky in postproduction. If you use a dome light to light your scene but still want to have the sky transparent in your .png, you may check a box on the dome light to make it not affect the alpha channel.
