Hi D5-Team,
I just discovered that caustics appear more detailed and brighter in the editor than in the final rendering. I set the strength to maximum (3).
In the example, you can see the editor window on the right and the rendered image on the left.
Hi @Albareus
It is expected that the preview window will have some differences with the final render, since the final image has a more accurate light calculation compared to the preview screen. Although the difference should not be significantly huge.
Anway, thanks for pointing this out.
