Vray environment lighting won't turn off.

[Sergio BarreraOro]

Hello, i have a problem regarding environment lighting and hdr maps in 3d max and vray:

 

I want to have a scene that is lit by an hdr map, and also have a hdr map in the environment slot, so that i can see the picture in the background, and also have an hdri ilumination of the scene.

But my problem is that the map in the 3dsm environement slot is casting a light over the scene that i cannot turn off. I want to turn off the light that the environment map cast over the scene, so i can use that exclusively to control how lit is the sky, and then use the vray environment skylight override to control how lit is the scene. Is there a way to do this?

 

Please help im kinda of desperate for making this work, and please excuse if my writing is weird as i am not a native english speaker.

Hi Sergio

I think what you need to do is create a dome light and add a VrayHDRI in the texture slot. Put whatever image you need in the environment slot, but then make sure the Vray Skylight override is ticked on and set to a black colour (and no map in the slot next to it). This will prevent the environment from casting light, but you will still see it in the background. The only light in the scene should then be from the dome light HDRI

Hi, first of all thanks for your quick reply and solution. What you suggested solved my inmediate problem but it didn't work exactly like you said(or most likely i did something wrong). Because when i turn on the dome light with the HDRI map it overrides the background environment map, showing the map from the dome light instead. Like I said, this solves my problem anyway, but is there a way to dissociate the lighting from the background map?(Or am i doing something wrong?)

 

Thanks again for your reply.

ah yes - I forgot to mention to set the dome light to be invisible. Sorry man.

 

...and depending on what you are doing you may need to turn "affect reflections" off as well
