    Memory: 32768MB RAM
    GPU: NVIDIA GeForce GTX 560Ti

    SETTINGS:
    GI enabled Interpolated Default - Sample Backdrop is checked - NO ISG Sampling- One distant light (1.5Lx) with angle 15 degrees and 8 samples - 1 back Area lights (10lx) 4 samples - 2 Rim Area Lights (35lx) with slight blue tint 4 samples.

    Render Time 8.10 Minutes
    NO NOISE REDUCTION USED

    Scene was transferred from LW11.3 - shaders were converted from standard to BSDF using the Convert Layered to Principled node command inside the surface editor.
    Old scene didn't use GI just Area lights and a dome light with soft reflections enabled for surfaces.
    Render Time 16.03 minutes

    Models are CatmulClarck SUBDs level 3 - 2,060,997 Polygons in TOTAL

    MY 2 CENTS:
    SIDE BY SIDE the new 2018 is superior in quality compared to 11.3 to 2015 plus the whole application feels very snappy, even in modeler manipulating large number of points is way faster than 2015.
    Rendering time is excellent but requires a small learning curve to get up to speed.
    View-port FPS is UP by almost 40 percent depending on your scene.
    Picking a Model from the scene to be used for surfacing PREVIEW is great.
    Presets are straight forward.
    Lights are well implemented . Easy to know what you are expecting if you have real life experience in photography or similar. (wish the color, intensity and object exclusion would work with multi-selection)

    You are not giving the most important settings : )

    Adaptive Sampling Min/Max?Threshold ?
    Reconstruction Filter and Pixel Radius ?

    Very good Ali! Just clicking back and forth between the 11 render and the 2018 render it is night and day different. The 2018 looks real whereas the 11 looks more like a really good Illustrator image. I do think though the plastic caps could be improved, but really nice overall.

    Sorry can't do, I'll see if it is possible to provide a different product with the same setup.

    I always start with the Default and this value is the Default.

    Ok. Surprising how the lw 11 render looks so bad. Like scanline render in 3dmax in the old days.

    Sure it can be a lot better, better results are guaranteed if you invest more time tuning surfaces.
    I was just showcasing how easy, straight forward and predictable the new BSDF Material and PBR are.

    Still needs refinement but for the time frame its great!
    Conductor and BSDF materials are used.

    How are you doing the bevel?

    Bevels are done in modeler using rounder and cleaning overlapping edges, tedious but worth it. (waiting for an edge shader).
