Hi,
From next version, it will be possible to get Soft Shadows with Real Time Sun in Iray.
This has been done by reimplementing Real Time Sun by an Area light.
Changing Sun Distance and Sun Diameter will result to smoother or sharper shadows.
Iray Real Time Sun parameters available in Iray Settings Editor > Sun and Sky
Two modes are available :
– “Use opengl parameters” adjust parameters to be as close as possible to opengl rendering
– “Use custom parameters” let customize shadows for Iray
OpenGL parameters are available in Real Time Sun Editor
Now let’s compare rendering :
With OpenGL parameters
On the left : OpenGl ; on the right : Iray
Sharp shadows (“None” value for “Shadow Smoothness” parameter)
Smooth shadows (“Large” value for “Shadow Smoothness” parameter)
With custom parameters
Distance = 100 ; Radius = 1 Distance = 100 ; Radius = 10 Distance = 20 ; Radius = 5
What do you think about it ?
