HDRP & Multiple Cameras

So what's the state of art now when it comes to using a gun-camera in an FPS with HDRP?

• Stacking cams doesn't work anymore.
• Does a solution exist?

 

In hdrp 4.10 you can write PP effect for this. In the 5.+ we can't do even that, because PPv3 is not extensible and PPv2 doesn't work, so I see no solution right now.

 

Was just about to create a thread on this too.

In some threads, people have mentioned workarounds to camera stacking/multiple cameras, but those workarounds have their own set of problems.

LWRP is getting its own workflow for camera stacking, but how about HDRP?

How can we get different post processing with UI vs game world?

 

So people doing FPS with HDRP have now all their weapons clipping into walls and thinking "oh maybe unity will fix it some day?" There has to be a way. How does the Unity FPS Sample do it?

 

FOV change in shader for the hands and weapons

 

Thanks for the answer! I guess i'm not experienced enough to understand what that means and how to replicate it. Does a guide exist for that? Didn't find anything on youtube.

 

in the fps project that unity has on github there is a shadergraph for the first person weapon models that changes the fov. its worth checking out as it pretty much negates the need for a second camera solution(for weapons at least).

 

The FPS example seems great for overlaying something in front of the view, but what about for far away objects?

For example, planets and other distant objects in space. This is trivial with camera-stacking and sort order, but how would you accomplish this in HDRP? Objects with huge scale at extreme distances means extremely far clip plane and problems associated with that. Doing it via render textures causes a lot of other problems as well.

Is there or will there be a method of handling this elegantly in HDRP?

 

Can any Unity HDRP dev give a suggestion of how to accomplish the above? Thanks.

 

Use a skybox

 

Thanks. The background objects are loaded individually and dynamically based on certain things, and some of them move slightly, so I can't put them in a skybox.

Anyway, for now I'm able to use a really large far clip plane. This causes problems with shadow flickering, but it's something I can try to minimize by messing with the near clip plane.

That does not work for HDRP.

 

It is working if you are not using fog on any of them (and maybe with some additional restrictions). But is really expensive.

 

Anyone have an answer, I just need something working, I don't care if there are 2 cameras or whatnot. I find making it really small and in front of the camera to be weird, seems like there would be a lot of issues (With what I'm making, because I have special interactions involving the location/size) .

 

If you are using HDRP 9.0.0 and Unity 2020.1 or later then you can use the Compositor

I checked that out thank you! So when I make the shader just apply it to the FPS Arms?
