Achieving Reflectivity on an Object (.obj or .tgo)?

[RichTwo]

I know I am far from being well-versed in many of the parameters of objects whether it's a .tgo or .obj.  There's got to be a ridiculously obvious answer to this but I've bashed my brains against the wall in my trying to figure it out and came out with nothing.  How does one get a nice shiny surface?

The object in the attached project came from CGTrader (free).  It's really a nice clean file, but all the surface shaders were default white.  There's over thirty of them (!) and they're obscurely labeled.  I can change the colors easily enough, but I cannot seem to get a reflective surface, like a coat of glossy paint.  I set the Fresnel reflectivity at 1 on every shader, but it still came out matte dull.  I left all other settings at default.

Thanks in advance for pointing out something I should already know.

This is affected by the Roughness parameter. Once you've set the "Fresnel reflectivity" to 1 (as you have), the Default Shader should respond to the Roughness parameter similarly to PBR shaders you see in other modern renderers, where there is a roughness or glossiness parameter to change the apparent shininess/glossiness of the surface.

[RichTwo]

I'll give that a shot. Thanks Matt!

Well, I set all thirty-plus default shader nodes' roughness factor to zero. Still using the Full Render, the image came out not only lacking in reflectivity, but had huge voids (solid black areas) not only on the object itself but on the terrain underneath (?!?!?).

So I modified the Quick Render to replicate the Full Render, and there were no voids but also still no reflectivity.  I tried again with the Full and the render came out pure white.

Thinking it could be a one-time only issue, I saved the project and closed the app and restarted anew.  A Final render had no voids and no reflectivity on the object, but a huge one on the terrain.  A Quick is now doing the same thing off and on.  None of any of this shows up in the pre-passes.

I have no other choice but to trash the project and start again from scratch - or simply give up.

It sounds like there may be an issue with your model.
I looked for it on CGTrader but couldn't find it, could you provide a link and I'll take a look at the model.

[RichTwo]

Thanks, Richard! It's near the bottom of the page.  Starting over and still having no luck...

Hmm still can't find it, I've searched for Aerosprinter, Aero4 and 80743 as well ...

Here is a direct link (I had to search for it under free). I'm taking a look at it now.

Thanks
Seems to be missing the mtl file.

NP.

May be easier to edit this projects object materials with the defaultness editor: https://nwdastore.com/terragen-tools/defaultness/ (This is not saving "Base Colour" anymore since Matt's update. Not sure why, the XML is still "diffuse_colour".)

[WAS]

Maybe there is an issue with the metalness, or maybe this is the specular roughness?

It doesn't seem very reflective.

Metalness 1, IOR 10

[WAS]

Base Colour 0, Metalness 1, IOR 10

I even tried recalculating and welding it to one material, and even that's black.

[RichTwo]

Thanks, guys.  I even tried using a single default shader hooked to all parts nodes except the one for the glass, "plane009" which I attached a glass shader.  I really didn't want to do it that way.  I'd like to have some color variations, especially on the aft engine exhaust fan.

I figure there's gotta be a way to replicate that glossiness like the picture shows.

Oh - and I gave it the name of "Aerosprinter".  Sorry for the confusion!

I wonder if it's "Objects" and "TGO" and lightwave files, cause I just did a base colour of 0, with metalness 1 for my sphere in another project, which is TG's vanilla sphere, and it is reflective in PT.

[cyphyr]

Setting the base colour to White and 0 roughness metalness at 1 gives a chrome reflective effect.
