Can't see the caustics
« on: March 30, 2016, 05:10:56 pm »
Why in the image with the lying floating perfume bottle I can't see the caustics of the perfume on the surface, although there is an IES light? I'm attaching a print screen with the lighting settings.

Hi,
Do you have a groundplane on your scene ?

I'm using an imported surface as groundplane.

Hi Zvi.
Are you able to share the scene?

Thanks.

There's something fishy about your glass. Maybe it's the way it is modeled. I couldn't get the caustics to show with any type of glass-material and/or setting. I suggest that you model and split your surfaces the way that Richard shows in the other post of yours: https://www.keyshot.com/forum/index.php?topic=12259.msg59849#msg59849

Without the glass the caustics shows up just fine.

OK. I'm going to check it.
Can you tell me how did you animate the movement of the gem stone?

Sure. It is just a 360 rotation along one axis, while rotating 360 degrees along another axis.

Thank you very much, you're so kind.
