shining metal materials and hdri?

[Barry Hayden]

I'm not getting something here..........

I am trying to render a pylon shaped object in a shiny metal like stainless steel or chrome and not getting the shine and liquid glossy look.

If I model a sphere and apply a material (AccuRender_nxt_Chrome) it looks like it should.

The same material applied to the pylon renders flat gray.

I am understanding the object needs an hdri to give reflections.

I am using default hdri sky and studio lighting. (nothing else)

What am I missing here?

I believe your pylon as materials attached by object to it. select it and use the properties options to change material assignment to by layer or remove with the widget in the NXT UI under material tab.

I exploded the pylon remove material, assigned new ones, everything works OK.  assigning materials by object or by layer

Guys.....

Thanks so much for your replies.

I followed instructions above, but still my pylon is flat gray.

I started a new .dwg

Created  a new pylon and sphere

assigned  material using acad "materialattach" command

Same results, sphere renders chrome, pylon is flat gray

No existe un problema, simplemente es que mientras la esfera refleja el entorno HDRi completo, la torre no tiene elemento alguno para reflejar, por lo qeu parece gris aunque posea el reflejo fisico

[Jorge Javier Lara Domínguez]

Aqui tienes una prueba son tu archivo simplemente cambiando el HDRi, y otra cambiando el angulo visual

"A problem does not exist, simply is that while the sphere reflects complete the HDRi surroundings, the tower does not have element some to reflect, reason why it seems gray although owns the physical reflection"

 

What is my best way to provide an element to reflect?

I have tried building walls and domes around the pylon and nothing is working. I can get a sphere to render but any flat planer object remains gray. Do I attach an hdri to a wall? If so, how?

Please see attached for examples of what I am trying to achieve.

thank you so much

Try a different HDR-- your pylon is just reflecting a flat area of the map.

[Barry Hayden]

I have tried all the hdr's included with NXT.

All the results are similer, the sphere renders, but the flat surfaces remain gray or slightly rose colored with the "grace_probe.hdr".

 

I have also tried rescaling the pylon larger and smaller, but no difference.

[Roy Hirshkowitz]

I opened pylon v2, turned on perspective, and changed the viewpoint a bit-- I didn't do anything else-- this is what I get. It's  the sort of thing you normally get with faceted objects.

[Roy Hirshkowitz]

Slightly different view with the edges of the pylon filleted (just for illustration.)  Again-- I didn't do anything else.

[Barry Hayden]

thanks Roy.........

I'm getting closer to understanding.

Aha! filleted edges, I think that is what I was "missing".

[Roy Hirshkowitz]

The perspective part is also very important when you're reflecting something at infinity from a plane-- otherwise you'll only be hitting a single pixel in the background map.
