Reproduce fresnel falloff curve as in 3Dmax

[Adam Trachtenberg]

You mean in the material preview? I don’t think you can turn it off if the reflection channel is active. If you could you would have no way of knowing what the changes you were making looked like in the reflection channel.

What I do sometimes when working with transparency/bump/reflection shaders is build the shader in the color channel, where it can be easier to see what you’re doing, and when I’m done I’ll copy it to the intended channel and delete from color.

Hello Adam,

I meant for the boll to look like this https://vimeo.com/102082368
Notice is sphere doesn’t have the reflection of the woods(trees) in it.

The sphere is showing the reflection of the trees — it’s just not as prominent because the Fresnel settings he’s using are cutting down on the reflection. Also, it looks like he’s using a custom scene for material preview, with the two prominent reflector planes in addition to the trees background.

If you really want to get rid of the trees you can create your own material preview scene. The standard preview scenes are located in your Maxon\Cinema 4D R1x\library\materialpreview folder. I would suggest that you modify one of the existing scenes and save it under a new name. You can put a different HDRI in the Sky Object’s material, or get rid of the sky object altogether. That way you’ll have no background reflections.

[Jeffrey Levenstone] “Are you talking from the point of view of the VrayAnvanced shader (Vray4C4D 1.9)?”

No. Are you asking from the point of view of the Vray Advanced shader? 🙂 That’s important to include in the question.

I have little to no experience with Vray.
