Nvida Iray Renders

Xfitz

I have been away from lDAZ for about a year and recently downlaods DAZ 4.9 with Nvida Iray. I must be doing something wrong because: When I light a scene the Iray render does not respond to the my lighting set up. l will attach two files to illustrate this - both rendered with the same single spot light. The 3Delight render responds how I am used to seeing with DAZ renders but the Iray render does not. Can someone explain to me what is going on?

What are the settings on the light?

By derfault Iray will be using the Ruins HDRI to lght the scene - you need to go to the Environment group in render Settings, on the editor tab, and set Environment Mode to Scene Only - and then you will probably want to adjust the Tone Mapping settings. You will also probably want to adjust the light - set it to Photometric mode and use the Luminance value to adjust brightness - though with just one light, especially in the absence of geometry to bounce light around, you are gonmg to have trouble avoiding noise.

Thanks.. You have given me a place to begin. Can you recommend a good tutorial source where I can plow thru the new settings that have appeared since I last used Daz -  I feel like Rip Van Winkle, waking up to a new DAZ3D world

Go to the main page of the forums. In software Daz studio discussion there is a locked thread near the top of the page called iray start here. It has heaps of information you might be looking for.

I'm pretty new to IRay as a serious option. Until about two weeks ago I had only tinkered with it and had used Reality/Luxrender or 3Delight by preference. Since I've had the new PC I have dived into IRay full time and I must say that the new DAZ videos are a good starting point, as are the Sickleyield tutorials.

Look on Youtube for the DAZ Channel: https://www.youtube.com/user/WWWDAZ3DCOM/videos?shelf_id=4&view=0&sort=dd
