volumetric spotlight less diffused?

Recommended Posts

Is there a way to make a volumetric spotlight more crisp and less diffused looking?  I have default spotlights set to volumetric in the attached, but not seeing where that control would be to make them less blurry and more crisp.

 

Thanks in advance for any help!

I haven't found a way to make a visible (or volumetric) light cone as crisp as the one at the top either. You can make it a little less soft with the edge falloff option under Visibility but that still won't quite get you there. I think your best bet is to make an actual cone and apply an alpha gradient to it. I've attached an example for you. Btw I don't think you need to use volumetric light in your scene if you go with actual lights, it looks like only "visible" is enough, should be faster.

I had a similar problem in that I just wanted more from it, I ended up rendering the light only on a pure black ( give all other objects a flat black mat ) and doing it in post, where you can double up the layers etc.

 

You can try doubling up the lights too but that has a bit of a different effect.

  • wow Janine, that alpha cone is a great idea, better rendering too and I will try the falloff too.

     

    Thanks deck - great idea - I will probably have to do some in post

     

    Thanks much!
