Title: "sharper" shadows in mandelbulb?
Post by: Chillheimer on September 28, 2014, 03:42:57 PM
Hi!

How do I get the shadows of the columns become more sharp? right now they are very blurry..

The shadows look like the lightsource is very big, thus spreading the shadow.
Can I change the size of the lightsource to very small, so the shadows of the columns have sharper edges?

And can I make the light reach further, without having to raise overall brightness?
if I just raise overall brightness it becomes far to bright in the center, but still doesn't reach as far as I would like it to reach..

Thx for any input!

Cheers,
Chilli

Did you try the "Hard Shadows" option?

I know you can also effect a light's intensity, but never experimented with it.  Maybe it can help with the other issues?

i didn't know that HS stood for Hard Shadows. But it was actually switched on.. so it's probably not really helping..
I had tried changing intensity, but this makes everything close to the light extremely bright, but still doesn't reach far enough..
the closest I could get is the attached image.. this is how bright I would like to have the  area behind the columns. but then the light on the floor in the middle is far too bright, no more details visible.
and the columns don't show any visible shadows, only very diffuse...

here's the parameters:
