DAZ Iray And "All New Worldbase XT Lushlands" Issue?

ColinK

My render seems just fine so long as I use 3Delight.

If I use Nvidia Iray all I see is a black window when the render is 'finished'

Any suggestions what I'm doing wrong?

It will depend on your setting, particularly in the Environment tab. What do you have the 'Environment Mode' set to?

Also, Worldbase has a Sky dome which you will need to switch off in the Scene pane depending on what Environment Mode you are using

Richard Haseltine

You will need to switch the dome off, or make it a light source with the Iray Uber Shader Emissive preset and set the mode to Scene Only (no point in using the Iray dome if you are blocking it with a modelled dome)

Okay, I found the "emissive" preset and it seems to enable a nice render.

Sadly, it appears to wipe out the clouds and sky blue from my sky dome, as well as washing out most of my shadows.

I can chase a few other discussions about shadows and Iray.

Do I need to fiddle with some settings to find my clouds and blue sky, or is Iray not really compatible with the sky dome concept ?

Thanks.

Greetings,
My systems are in the middle of a long render, but my recollection is that you would pull up the Surfaces, look for the diffuse of the sky dome, then apply the emissive shader, then edit the 'emission color' to have the same map as the skydome's diffuse had. Not sure that'll work perfectly, but it's at least a start. (It's awesome for computer screens, no idea for skydomes; I broke myself of the habit of using them, which is one reason I don't really use Worldbase XT.)

Do what Morgan said above but in addition drop the intensity of the Emission. Applying the Emissive shader will make the Diffuse colour black you will need to change it back to white, Your goal it to make it render and not emit too much light that it effects the rest of the image.
