Grass Textures and Detail Meshes in Beta 2018.3.0b10, 11, 12 and f1 aren't rendered.

Note: I already posted this in the beta forum. Was advised to post it here.
https://forum.unity.com/threads/una...n-in-beta-2018-3-0b10-and-2018-3-0b11.587086/

I'm unable to draw grass textures or detail meshes on any terrain. Or at least it doesn't get rendered.

I have tried various combinations of brush size, opacity, target strength, detail distance etc. I even tried to add details via script. Nothing worked. No error messages are printed. It says "One or more selected brushes are read-only" in terrain inspector though.

When disabling billboard on the grass texture settings pink squares are being rendered.

Steps to reproduce:
- Create Terrain in Unity 2018.3.0b10, 2018.3.0b11, 2018.3.0b12 or 2018.3.0f1 with HDRP
- Update HDRP (up to 4.3.0)
- Add a Grass Texture or detail mesh
- Try to paint

I don't seem to be the only one with the problem. There are at least 2 posts in "Graphics Experimental Previews"

and one on the Unity3D subreddit

Is this fixed in the release version of 2018.3?

EDIT: this is still happening with the release version.

Does anyone have a workaround that doesnt require to place grass as trees?

 

Do you have a workaround for now? If there is a way to make a compatible shader in shadergraph or by hand and get the terrain to use that for now, then that would suffice! Even if you can only give super high level advice on that matter, it would help me and a lot of others who in the meantime need this!

 

I'm looking for workaround as well, I wasn't able to get it to work with shadergraph shaders as well...

 

@wyatttt would you be able to direct us on what is required to get some sort of grass working using shadergraph, or using anything for that matter?

This is the only thing stopping us testing HDRP with projects, currently stuck on LWRP because of this

 

Thanks a bunch this is exactly the info we needed to stop blocking progress, thanks again!

And I look forward to the fix

 

Thanks for the info.

Detail Meshes dont't get rendered with LWRP either though.

 

Really? they do for me currently?

@wyatttt are you / the worldbuilding team aware of this?

EDIT: anyone interested, I have posted our current workaround to this problem in this thread: https://forum.unity.com/threads/unity-plan-for-rendering-lots-of-grass-or-rocks-greebles.600277/

 

Simple Objects (Quad, Imported Models) get drawn. Composed Objects or Prefabs don't.

 

Any updates on this?

 

Still broken in 2019 beta. Unbelievable.

 

Сurrently this is in RenderPipelineResources. Just little bit wrong to setting not working shader by default

 

Any updates on this? Can I paint Detail Meshes that are Prefabs in HDRP?
Currently, all the Details that I paint are just Pink. They are a Prefab with an HDRP/Lit Material and MeshRenderer.

I'm on 2919.1.9f1 and I'd like to second Sonorpearl's question. Details Meshes still showing up as pink.

I'm also noticing that with detail meshes it doesn't like it if I have a Prefab parent node, this makes it so I can't have LODs on my Detail Meshes correct? anyone else encounter this or know the current workaround?

 

Having the same issue with detail meshes showing as pink, holding up development on a project at the moment too as we can't find a fix!

 

Same problem on 2019.2.5f1....

 

I reported a bug for it also

 

Still having this issue in 2019.3.7f1 at the moment.
Also now getting the error message "The current render pipeline does not have all detail shaders". Any updates?

 

I just took a sneak peek at 2020.1.0b, which of course is Beta, but the problem still exists there. So from 2018... till now, this problem has existed. Is it that difficult to paint detail meshes on the terrain. I'm actually using 2019.4 HDRP for my project atm, and was holding out for this, but it doesn't look like it's going to be resolved any time soon. May have to jump platforms, which is a real shame. I've also tried to use the shader graph with the detail mesh / terrain system, and there are serious issues with that too. If you have a terrain based game and need foilage of any type... then don't use HDRP... I can't comment on whether it works in URP or not... but you can always try, I guess.

 

Now, instead of pink textured meshes that can be overridden with some tweaks (just search "hdrp grass" on youtube), grass just simply doesn't appear anymore and detail meshes are still not overridable.

I just updated to 2019.4.11f1 this afternoon and discovered this remains unfixed. There's no link to documentation or explanation in the alert message. Please update to communicate to users, as this seems to be a bit confusing it's not ready out-of-box. Alternatively, perhaps within the Terrain settings add an option to override with an ShaderGraph-supported vertex shader? The documentation does say "this only works in URP", but that's it..

Since grass is an important detail and is key in making HDRP scenes look as good as they do, is there an approximate timeline when this could be addressed? I would upgrade my project to 2020.1 but I'm a bit concerned it's broken there as well

 

What ended up working for me is making sure the grass objects are using GPU Instancing!
