Help: iRay render is missing the lighting from Texture shading

vincent_4c1ea97610

Hello everyone,

Thanks for taking the time to read my issue. 

But perhaps first a small introduction is necessary. My name is Vincent and I'm a UX product designer that has a passion for painting miniatures and fiddling around with 3D programs to get a basic understanding of how it works so I can create and print my own models!

The question; I guess it is somehow a rendering problem. I've been playing with settings but somehow. I can't get my lighting in the render to work. In the main pane, you can see what I'm trying to accomplice and for me, that looks good (for a first try) but if I render in de small preview pane all the juicy stuff is gone and it's back to a kind of default. What I'm I missing?

Thanks in advance for your help!

That actually looks like Cartoon Shaded, it's an OpenGL drawstyle and so does not use or show many features of Iray - but it does apply some posterisation effects. Rather than use Iray, in the editor tab of render Settings (at the top of the pane on the left in your screen shot) set the Engine to Viewport. You could also use 3Delight and aply the pwToon shader if that is the effect you want but with more options for lighting.

Hi Richard, thank you. But I can't get it to work. The lighting in Iray. So I went to the basics. Created a new scene, removed all the lights. The main pane is texture shaded and the small pane next to it is iray. At the render setting disabled the Environment Map (set to 0.00). Then added a spotlight pointing at the model, and boosted that spotlight the Luminous Flux (Lumen) to 5000.00.

Still, the model stays dark. But I guess I found it...  Luminous Flux (Lumen) should be in the 1,000,000.00 to have an effect in iray.

It's better in the lonmg run to adjust tone mapping to match the light rather than vice versa (Create>New tonemapper Settings node, if you don't yet have one).
