Iray shaders with 3delight

So, what happens if you use an Iray shader on something but render it with 3Delight?

Possibly nothing...but more likely a very sub-optimal render or 'blank'/white figures.

Whichever renderer you use is looking for parameters on the surfaces with particular names. I don't think there are many exact names in common between 3Delight and Iray.

I suspect this is probably why many custom 3Delight shaders don't show up properly (if they show up at all) in the Viewport, until you render. Remember that the Viewport uses a renderer as well, in this case the OpenGL of your graphics card.

Okay, that's what suspected would happen. Thanks everyone!

Yeah, and the few they do have in common don't necessarily mean the same thing...

There's a bit more as to why the custom shaders are no-shows, but that is part of it.

The one Iray-only product I've rendered in 3DL ended up excessively shiny.

Then all it would take is a few minor adjustments to tweak the specular parameters.  Some would basically require starting from the raw maps and building a new material from scratch.

I use a "Matte Rubber" shader on top of the 3DL shader to get rid of the gloss in iray. It's a quick and dirty workaround, but it works, and doesn't (usually) affect anything else.
