Jpg bitmap as a enviroment?

[fabw]

Why when I replace vray sky map in enviroment withe jpg bitmap, when I render with the same camera settings my sky is very dark?

I don't know, but a couple of things to check would be:

 

In your Gamma/Lut setting that you tick the "Affect Material Editor" box

 

In Vray Settings Tick "Affect Background"

 

Lastly you can try adjust the "Output" on your map to something more, like 3 or 5 or whatever it takes.

 

Are you setting the map to environment and spherical? There are a lot of things it could be, all are simple, but in what context is it dark? Rendered? Viewport? Both?

 

Good Luck.

You'd be better off compositing the background in post. Leave the vray sky as it will cast light and reflections. Save out to a format that carries an alpha channel, such as targa or tiff, then put your jpeg behind your geometry in photoshop. An environment is only going to be beneficial if it's a spherical map. You can do a horrible fake by wrapping a jpg background around your scene and tiling it, but the 8 bit image will give dull reflections.

The reason you are not seeing the jpg is due to exposure. Are you using a physical camera?
