Light Edges too hard

[emilyLOVESlime]

I'm rendering an interior scene with skylights and am using directional lights and the GI to simulate the sun. The general lighting is fine, but when the light hits the floors and surfaces the edges are too hard. Is there any way to soften the edges without decreasing the intensity of general lighting?

Why you don't use the real sun. The sun is to mimic the real sun and you can adjust the shadow by increasing the size of the sun. If you still want to use the directional light try by increasing the radius value.

Thanks for your reply!
I haven't used the sun because I sometimes have problems getting the light to go into the skylight at a certain angle; I felt like I had more control with directional lights so therefore used those instead. I will try a sun system next. How do you make the sun bigger?

However, the radius adjustment for the directional light, isn't that for shadows, not light?

By increasing the radius you will smooth the shadow.
To increase the size of the sun, go to the sun parameter and increase the size value. Once you create the sun you can rotate manuali using the rotate command to place the sun in your desired position, exactly the same way how you place the directional Light.
I attached 2 image that I made using directional light. The first one have Radius = 0 and the secong one have Radius = 0.05

Radius = 0


Radius = 0.05
Please see the difference on the shadow.
Is that what you want?

This is exactly what I needed. I was thinking it was only for shadows, but obviously they are very related. Thank very much!

The darker areas are really shadows.
