Hdri sky issues in 3ds max, 2016

[belemaogan]

Please i am having a problem. i rendered a reflective sphere using vray plane light in the scene, and applied a hdri sky to the dome light texture also in the scene, and am getting an image in the inner core of the sphere, instead of just the outer core. All my lights are invisible. see attached file

Physics my friend, just physics. if you walk outside your house, and place your hand in front of your eyes, what you will see?? your hand or the sky??

V Ray and most of render engines are based on real-world physics, what you see in your scene is exactly what you should hope for your scene setup.

Having said that, since it is computer generated images after all we can always bend the rules.

in your case you not only need to 'hide' your light, you can also make it invisible for reflections glossiness and diffuse channel. if you only need a diffuse lighting, then uncheck all the other properties and bingo you get your scene as you imagine.

But be aware this is not a real effect, this is just CG trickery

in the modify panel, and option tab. i unticked "affect difuse" and "affect reflection". nothing changed. i want the reflection of the HDRI sky to be on the surface and not the inner core

You need to change the properties of the light planes, those are the one you want to hide not the dome light.

Go to the light planes and uncheck affect specular and affect reflections.

Thanks alot. It worked

i know this question has been answered. Please i will like to know how this options work "affect specular" , "affect diffuse" and "affect reflection", so i know how to play around with it in my work
