Title: Real Reflections
Post by: ifurquez on 2018-02-15, 19:58:22

Hello everyone, this is my first post in this forum and I do it to raise some questions.
I have been working on a personal scene to be able to improve the use of materials and light. For this I have tried to replicate a real image.
I have encountered the problem that sunlight is not reflected in the glass.
I have manipulated the IOR, but when I increase it, I lose the part of light that crosses it.
I would like to know if there is any parameter to manipulate to achieve the effect of the reflection illuminating other parts of the scene.

I'm sorry for the google english translator.

regards

Try changing your  max sample intensity in the performance tab to something like 200 and see how that works out

What you are trying to achieve are caustic reflections... bit hard, tedious to achieve, tho many of how to, what to do around the forums + improvements in plans (https://forum.corona-renderer.com/index.php?topic=18385.msg115365#msg115365).


;) use Search

Yes, those are reflective caustics.
Raising MSI may help get some light in that part indeed, but generally some kind of workaround or faking would be necessary. One idea would be to place some kind of light in there.
And here is a tutorial on rendering caustics separately, which should work as well in this case: https://forum.corona-renderer.com/index.php?topic=19367.0
