Hair rendered with New "High Quality Line Renderer" does not work in XR #55

Open qlee01 opened 1 year ago

Not sure if this is even a topic for this lib, probably this is due to a bug in HDRP, I also did a regular Unity bug report for this: The rendering option "High Quality Lines" does not work correctly in XR.

Tried on latest beta (2023.1.7b). Hair gets rendered twice in low quality in XR. Without XR, everything seems to work as expected, looks much better then with standard line renderer.

Hi there,

I have the same problem "HDRP High Quality Lines" just doesn't work when compiling no matter what mode you use it. hair disappears. It works with the other "strand tenderer" but nothing else. A pity since the only thing that makes the hair look good is in the "HDRP High Quality Lines" mode.

Did you find any solution?

Hey, unfortunately not yet. My bug report was accepted by Unity QA, if you like, please vote for it here: https://issuetracker.unity3d.com/issues/gameobject-is-rendered-incorrectly-when-the-high-quality-line-rendering-is-enabled

I have not tried build yet, as it clearly does not work in Editor as long as Single Pass Instanced is used.

It doesn't exactly work in the editor. If you compile it, it won't work for sure. I already gave you a vote for this.

Maybe it works in the version that the hair was released? (I didn't try it there) but in 2023 beta for now not

The "High Quality Line Renderer" is a new feature in 2023.1, so there is no other version to try (besides 2023.2 alpha). And I agree, this is the only way to make the hair look really good.

Friend, I found a provisional solution. At least it works for me for what I need.

It turns out that I used Enemies again in the editor with its timeline and the hair works fine in high definition. So I asked why it works there in the "timeline" when I hit play in the editor.

and I realized that the character has some activators. (Basically when you play the editor, the character is not activated. It is not seen in the scene. But it has an activator that makes it appear after the presentation of the Enemies short.

So I went to my scene that I had created for myself with a demo hair. I turn off the GameObject that has the hair instance. I mean the script. I play the editor and activate the GameObject and magic works. Try that and it should work for you.

So it works in Single Pass Instanced XR for you with this method?

I don't use it for XR. I use it for cinematics.

But what you can do is activate the GameObject through a script when you compile put your script that activates the GameObject after 1 second and I'm sure it will work

This issue here is about rendering in XR, as the title says.
