Weird Spot Light

[Organic]

Hello Community,

 

Recently, I started to want my interior design to have smooth lighting everywhere without any exaggerated lighting effects and shadowing. 

I used Custom Renderworks with no indirect lighting and environmental lighting from the current background. It came out perfectly like what I needed.

However, there was always a really bright spotlight in my rendering while all my lighting was turned off. (I needed to photoshop it away every time which is annoying)

I tried other materials besides chrome and it still has the effect. 

Is there any way to fix the problem? Or any option I can do to have a similar rendering effect that shows the design itself? ( I want a simple bright looking design without any spotlight)

This looks like it could be the "default" light source which is normally over the viewers left shoulder.

 

Try putting a light in the drawing and turning it down to a very low level (or even off).  Having a light in the drawing should deactivate the "default" light.

Thank you so much!

I have a symbol in my library that I add for just this scenario.

 

It consists of 6 light objects set to directional.

 

4 of the lights at point at 90 degrees to each other and the last 2 point directly up/down.

 

Set them to not cast shadows.

 

You can adjust the intensity of the symbol and I find 50% normally does the trick.

 

this is as shadowless and even as I can get and is good if you want to have completely even illumination.

@markdd Question.  What makes 6 directional lights better than a single point light if all are set to no shadows?

[markdd]

The directional lights can be placed anywhere and there is absolutely no fall off. Point lights have intensity falloff even when set to none. 

 

Most importantly though, they are directional, so the position of the light will make a big difference. It's hard to explain without an example....

@markdd wow. This method is extremely interesting. It did what I want. May I ask for a larger interior space, how many of these symbols would you put into?

[markdd]

You only need 1 symbol as there is no light fall-off and the symbol can be positioned anywhere on the design layer.

@markdd I am not sure if I make the symbol wrong. I turned the symbol brightness to 50 and its overexpose. And this is what it looks like with 25. The lighting is not smooth. I put two symbols, one outside and one inside. Did I make the wrong symbol? I have all six lighting closely attached each other. Thanks

[markdd]

All the lights need to be directional. It looks to me as though you have a point light in there as well.

[markdd]

You also need to turn off ambient light in the Lighting Settings dialog.

@markdd I see... let me double-check with the point light and the setting. Is this what the symbol should be? or it doesn't matter much. the left one can't be shown but its there. And I also have the top and bottom ones.

[markdd]

Yes, that looks about right.

@markdd Hi, somehow it still has the white spotlight there in the center. And it feels like a greyish filter over it now. BTW, thanks a lot for all your responds. 

[markdd]

Try turning on ambient occlusion and indirect lighting to interior.

@markddThis is definitely the effect I am looking for! Thank you soo much. But, just this annoying spotlight is popping up... @Pat Stanford Would this still be the default spotlight? Is there any other way that I can remove it? Thanks all

@markdd does this way more than I do, but that looks like the reflection of your directional light.

 

The only way I know of to get rid of it is to turn down the brightness of the light and turn up the ambient lightning and/or the brightness of the Renderworks Background.  But hopefully someone who actually tries to render things to look good will help us both out.

Or maybe rotate your lights by 45 degrees so that none of them are pointing directly away from the camera so you will get less reflection.
