Immortal Elegance textures & Iray

EmotionalOutlet3D

I seem to be having difficulties applying the uber shader with the Immortal Elegance textures. I've seen this car rendered in a few nice Iray renders so is there some sort of trick I'm missing?  I've tried Ctrl + double click to ignore but keep losing the textures.  I can add the textures in the base color on various surfaces but is there an easier way?  Any help greatly appreciated.

Which uberShader? Some of the files in the Iray presets are not in fact Iray Uber Base but are custom shaders without the standard channels so there's nowhere for the maps to go. Also, if the materials on the car use a shader with non-standard channel names then DS won't be able to match them to the channels in the Iray Uber Base shader and again the textures will be dropped.

Hi Richard,

It is the Iray Uber Base shader.  But that may well be that the extra textures are using non-standard shaders as I think it is an older prop.  A lot of PA use that car in their promos so hopefully they will share their tricks ...

I suspect the issue is that the Carbody surface has a custom Studio shader. It's the ONLY surface on the entire car with a custom shader; the rest of the car is Daz Studio Default. The custom shader also has two different image maps in it; one is the color/diffuse map and the other is a grayscale opacity map.

Because Carbody uses a custom shader, when you convert to Iray Uber, the converter doesn't know what to do with two image maps going to the same slot, and it drops them both. You can get the color image map back by plugging it into the Base Color slot (should be in runtime/textures/ELELE/Immortal Elegance or runtime/textures/ELELE/Immortal Elegance/Upgrade, depending on which textures you're trying to use). The grayscale one ... I think it goes into the Cutout Opacity slot.

From the look of my test image, the fins need some work as well; I gather they're not part of the Carbody surface.

EDIT: I take it back. The fins ARE part of the Carbody surface, so I have no clue why they're transparent here. If you remove the Cutout Opacity texture, they become visible, but the car itself changes color from red to black and you lose the gradient in the flames.

If you just want a solid, high gloss color, you can replace the actual texture with one of the Iray carpaint options, and that should work. Getting the flames to show up properly ... no idea how to make that work at the moment.

Thanks vwrangler!  I had some spare time this afternoon and played around with this.  I'm not an Iray expert so my solution is just to try things and see if they work.  The trick seems to be to add the texture to the base color field and change the color to white and change the base mixing to PBR Specular/Glossiness.  I have no idea why that works but I'm not big into theory. :)   PS it is supposed to be black not red going on the vendor's promos.

I've attached an image with one of the flame textures.  Not real happy with the tires .. for another day, I guess. :)

Whatever you did, the flames look great.
