    I have worked with this file and was trying to bring the reflection as it is looking great in scooter example.
    I tried referring all possible ways to set material and settings but somehow
    I cant get that crystal clear glass reflection as it is seen in scooter example

    Here is my 3D watch file – (The glass of watch doesn’t get that great reflection)

    @visualizer, your work is terrific! Making convincing-looking glass is difficult. I am not an expert but here are a few thoughts.

    The scooter’s windscreen is curved, and your watch crystal is flat. The curvature difference will cause the reflections of the HDRI to play differently on these two objects. Reflections are more interesting on curved surfaces. The edges of your watch crystal are sharp. Would it be inappropriate to give the edges of the crystal a small bevel and shade it smooth? If you could, the crystal would pick up many more glints of light from the HDRI.

    Keep in mind that glass is never 100% clear; even a sapphire watch crystal. If you look at the scooter glass, you will see that the Glossy BSDF node has an RGB hex value of E7E7E7, a very light grey. This gives the glass a little color and presence even when it is not reflecting an HDRI light. I think that you are doing this. When I look at the watch crystal from the side, I can see the fresnel mixing in a darker color.

    The other concept that stumbled across is that glass is never 100% clean. Even if I am building a configurator for a new product, I have found that mixing in the slightest grunge map into the glass shader adds realism. But, in my case, I am configuring machinery and not jewelry. The glass is not the focus of my 3D scenes. In your case, this technique may not be acceptable.

    Lastly, you can try different HDRIs. The stock HDRI is very dramatic, but it does not have a lot of detail. Unless the watch crystal is pointed at one of the white lights in the HDRI, there is not much of a reflection.

    Hey
    Jem,
    Greetings!

    Very correct observation ! ( I hope “terrific” means good :) and guess its not that bad … :unsure: haha ). Of course due to too much of details the file has become heavy in size, that is slightly terrific :) :). However I m working on niche virtual 3D product catalog & wanted some samples of extremely detailed quality.I find Verge 3D still needs to have some key features included, I compare it with Sketchfab features. But honestly feel V3D has almost all of it to beat it & some needs to be there really.

    As you rightly said I observed the same about curved surface and flat one. However even that also not giving the desired effect as seen in scooter example.
    I found there is a puzzle called “screen space” in “post-processing” I played with it a bit. Needs V3D team to clarify on it in some tuts.

    I am also from Engineering & Design-Innovation field. Working in Industry 4.0, IoT, A.I. related AR/VR field. Working as consultant to MNCs where they are very specific about visual quality parameters for their products.

    I m trying to achieve it but somehow not reaching to expected finished results.

    Cheers ! :good:

    THere’s nothing special used in this scene: no posteffect or anything other. Only Material with blend transperency type. You have a flat glass on the watchs that’s why it works dab. Try to make it little bit spherical or try an hdri environment with more details.

    Ok I will try with little more tricks as suggested by you & Jem as well

    Cheers ! :good:
