03.08 Adjusting the lighting settings
Now go back to the original scene by clicking on the top RenderView_00 tab and start the render in real time.
We will focus first on the IES lights. To isolate the IES lights, the other lights in the scene can be temporarily disabled. In the Lighting section of the Asset Editor , select the Directional Light ( Spot Light ) and expand the configuration. Disable the Sport Light and the Spherical Light .
Now let's render a part of the rendering window, select the Render Region icon and draw a rectangle in the area where the IES lights are displayed.
Now select the type of IES light, this type of light has the lighting information within its configuration but to get a greater effect of this light we need to modify it so we click on " Override Intensity " and we will set a value of 4000 for that these lights have a little more presence.
Now define a region of render of the image to viaulizar the light of the kitchen.
Give the spherical light a warmer tone.
And give it an intensity of 100 .
If necessary, enlarge the render region a bit and then select the Spot Light and activate it.
Select the Light Spot Light again and activate it, open the light point configuration and where we can see the parameters Decayand Penumbra Falloff , change the value from Decay to Inverse to square ( Inverse Square ) so that the light decreases as it is moves away from the starting point, also changes the Penumbra Falloff to Smooth Cubic .
The scene becomes a little dimmer as a result. We have to change our intensity a little to account for the natural decomposition of light. First we set the Units and change them to Radiant Power (W) and that gives us too much brightness with a value of 30.
Lower the intensity to 8 .
Now displays the option cone angle ( Cone Angle ) and increase it to 1.8 for a wider cone in this type of lights. The penumbra angle ( Penumbra Angle ) softens the light at the edges of the cone so it is better to set a value of 0.8 to achieve a more natural light effect.
Try some regions to see the contributions of light to the scene. In the chair, notice that the shadows are quite sharp.
Change the Radius of the Shadow ( Shadow Radius ) to 1 to add softness.
When you like it, disable the render region in the Frame Buffer to update the entire image. Put an amber tone on the directional lights ( Spot Light ) in its Color parameter .
You will see that a little color is good for a lot.
We are going to do the same with the Spherical Light of the kitchen.
This is a general light in a corner that we do not see directly, use a dim light and no accessories as this may make sense.
