Title: max Distance to Reflections/ Refractions
Post by: mraw on 2015-07-08, 11:35:21
In other Renderers there's a usually a max. distance setting in the Refl/Refr. parameters. If used right it can cut down render times significantly.
Will a max. distance value an option for corona materials as well? Or I simply misunderstand the technical background of corona? Then please explain.
Many thanks...

maybe this was discussed before on the forum. I searched, but didn't find it.

In Corona this would probably bring close to no performance benefit, and in general, Corona falls into generation of renderers where fakes actually slow things down.

If you are willing to sacrifice some physical accuracy for better rendertime, then there is a lot better and less destructive way to do so. Simply decrease Max. sample intensity parameter. Just do not go too low (under 2), otherwise you could sacrifice way too much accuracy and your renders could start looking weird.

If rendering of reflective/refractive things goes exceptionally slow for you, then there is probably some error with the material config or render settings.
