Title: Abbe Number lower than 10
Post by: kined on 2018-09-19, 23:51:22

This would be grate to have Abbe number that can go to the lower number than 10, I had to switch to VRay just because it can go to 1. Could you make it possible the same way for Corona Material.

Best,
Ed

Zomg! :)

You need to expose additional parameters of your material first, then locate "dispersion", and plug your controller in there.
I am guessing that the minimum value of 10 is a kind of safety measure, so I can't guarantee what will happen once you override it. ;)

Does that work? I mean is there difference between 10 and 2?

Yes. Just try it.

(moved back to feature requests as we may look into this - should we remove the value 10 cap?)

Yes, please, especially if it's just an artificial cap without any further reason. Remove it and let us abuse it :D

I am trying to achieve a look that was done in Arnold, and I realized its because the Abbe number used in arnold was .1, which drastically distorts colours and gives a very cool effect: https://www.behance.net/gallery/86367939/Alphabet-Dispersion?tracking_source=for_you_feed_featured_category

Please allow users to start at 0, and not 10.

I noticed this feature was asked over a year ago and I'm not sure how complicated it is to implement this, but it was be great if you could.

If this is not the right place to ask for a feature, please direct me to the right place?

Also on a side note, I would love X-particles integration.

Title: Abberration Number lower than 10
Post by: ddaker on 2019-10-16, 18:13:20

I really need a lower Aberration number under the refraction node.

Please could you let us know if it is even doable, Would really love it for a current project I'm working on?

Yes, it is doable, look at the very first reply in this topic - controllers lets you enter any value for the abbe number.
