How to get rid of an ambient light ?

Anonymous — Wed, 12 Dec 2018 21:56:38 GMT

Hello !
I'm really super new to 3ds max, and i try to get out of a struggle for hours now !
Here's the thing : I created a plan with some "topography" (with Edit Poly), then i wanted some kind of sun/star to illuminate the scene. So i built a sphere and apply some white Physical material and play with the light emission.
Then i try a render with Art Renderer. But in the render, the scene is exposed with some ambient light, so the sun is no longer the sun 😞 (i also tried with Arnold)
I wanted to create a totally full black scene with only this sphere as a source of light.

To get out this situation, i went to the environnement panel and put the Global Lighting to 0.0, but it didn't seems to work !
I tried to play with all the settings in the material, or tried to find something with the rendering, but as i'm a newbie to this, i don't really know where to go, what to touch !

So i went here after googling the problem, but didn't find any answer. I don't know what to do 😞
Thank you in advance for your time and your answers !

(and i'm sorry for my english, it's not my native language )

Hi @Anonymous

A quick trick I learned to turn off default lighting is to create a new light in the scene (say a standard Omni light), and then turn it to "off". As soon as you create a light object, it will replace the scene default lighting. Turning the light off effectively cancels out it's contribution to the scene lighting.

Hi @brentscannell !!!

That's seems to work ! Now, my scene is really dark but i think i can manage with emission to get something ! (maybe use a real light and not the emission of the material ! )

Thanks a lot !!!!

That's good to hear @Anonymous

I tend to prefer real lights over emissive materials, however you can get additional control on your lightness/darkness by tweaking the "Global Exposure" value in the "Environment and Effects" dialog (same place where you tried adjusting your global lighting) accessible from the Rendering menu.
