Title: Ornatrix problem
Post by: Daskydesign on 2017-11-20, 11:00:10
After I abandoned the idea of using 3ds max native Hair Fur (Corona does not read the .stat files in DR).
I decided to try Ornatrix.
Before I buy this I want to be sure that everything works well.
I'm trying the demo version but I have a problem.
At the end of hair I always have a lot of noise (in animation this is even more evident) and there is no antialias (as can be seen in the attached picture).
This tutorial explains how to solve the problem in Vray (because Ornatrix fully supports Vray)

But in Corona how can we solve the problem?

Don't use any kind of opacity with hair. This is a "fake" and most probably it will only make rendering slower.
Instead, you should probably allow more passes to be rendered (=better AA), so you can just try lowering GIvsAA balance in the Performance tab of Render settings. The default value is 16, so you can check with 8 and 4, but probably not less than that.
Another idea is making the hair a bit thicker at the end, instead of going down to 0 thickness.

Hi Maru, I've tried your solutions but as you can see from the attached image nothing has changed.
I set GIvsAA at 6 and change the hair end with a value greater than 0.

Does it seem that there is nothing to be able to work with Hair and Fur animation in Corona.

The image looks correct to me. There is a lot of very thin meshes in there.
How many passes rendered is this?
