Ornatrix/3ds Max/Corona renderer: How to improve hair sampling on render?
In this video, I will explain how to improve hair sampling during Ornatrix hair rendering in 3ds Max/Corona Renderer.
Not everyone knows and understands that, more often than not, poor quality hair sampling is not really sampling, but just a small resolution for your task, or you just haven't rendered enough time.
For CloseUp - it is enough to move the camera, increase the resolution - if the first action is not enough and turn off the option "Render as planes" in CoronaHairMod.

The Q&A section is video answers to subscribers' questions which they asked in various groups, comments under videos, etc.
This video I recorded a long time ago, when there was a page and group in VK.
As I said, I'm just transferring all the video answers from the old channel. If something is out of date in such videos, I supplement them with new and up-to-date information.
A list of current questions that are hanging in the queue - you can see here

TIMING:
0:00 - What will we talk about in this video?
0:37 - Demonstrating a HairSampling issue in CoronaRenderer from a subscriber.
0:53 - Showing an example with the same issue.
1:18 - Increasing resolution to 4K to fix hair pixelation.
1:22 - Turning off the Render as Planes option in CoronaHairMod.
1:28 - See what happened. As you can see - the issue is fixed. Yes, you can zoom in on the camera and thereby improve the quality in a small resolution. But more often it is the need to render a large resolution, so that when you zoom in the renderer - we don't see pixels and bad samping.
1:34 - Checking hair with CoronaHairMtl
1:45 - Reduce the thickness of the hairs to check the rendering quality with this result. Since in the subscriber's example - they were just thinner.
1:53 - Here I say always look at the picture at 1:1 scale. But if there is a need for 2:1 quality, etc. - just increase the resolution. For example, you need such a picture for a bigboard or for printing. At the same time, if you need just a close angle - just zoom in the camera and turn off the "Render as Planes" option in CoronaHairMod.
2:16 - If you liked this material, please don't forget to like this video, subscribe to the channel and write at least "thank you" - in the comment below it.
