Noob lighting question

strontium_99

Hi all,

Is there a way to get the viewport image to give a more accurate display of the final render lightening?

It’s just I’ve switched the headlight off on my camera and my view port image is nice and bright etc. But when I come to render the image is really dark. And it’s a bit of a pain to have to wait for the image to start rendering before telling that the lightening setting are all wrong.

Big thanks.

Hi

If you have powerful enough graphics cards, you can switch the viewport to 'Iray interactive'.

If you have less powerfull graphics cards you can set the Aux. View to Iray and keep the Aux. window small.

If you have a non-iray graphics card, then test rendering is the only option.

Hi Prixat,

Thanks for the response. I've got an Nvidia GTX 970 4gig card. 

How fast should the Iray window update? It's very slow at the moment.

Thanks.

Is it slow even with a simple scene (e.g. a cube and sphere on a plane)?
...for simple scenes it's near instant.

Check in the Render settings/advanced that you have the 970 checked for use (in Real and Interactive).

Oh right. Think I've sused it now.
Seems to take a while to initially render the image in the Iray Interactive, and then it's almost instant working on the scene from there.

Nice one. Big big thanks for your help.
