Any way to easily turn HDRP off in editor or on certain platforms?

Unity Engine

For one project I’m on, we apparently have to use HDRP for the real builds because the visual director insists on it. But it makes Unity essentially unusable on my Mac — even after making a custom HDRP profile with everything turned off, the scene and game views produce seizure-inducing flashes, and while running, cause the whole computer to freeze for a few seconds, every few seconds.

Is there any way to tell Unity, “Don’t use HDRP in the editor”? Or “Don’t use HDRP on macOS”?

Or failing that, how hard is it going to be to set up two projects that use all the same assets, code, and resources except for HDRP?

Hi, don’t think this answer your question but if you setup GraphicsSettings.currentRenderPipeline to null then it disable HDRP.

Flashes sound like issue with autoexposure. There is a fix for the initial flash on some newer HDRP, can’t remember which versions the fix landed on.

You can’t just trivially turn it off since all the project materials are configured for HDRP. If you disable the HDRP asset, you’ll find all your materials turning to pink.

I’d pursue on path that makes bare minimum conf for HDRP, it’s really easy to overlook some things on it. You can also turn off plenty of frame settings to fully turn off some expensive feats. I’ve gotten HDRP to scale fairly low (not as low as URP but still like only 35% of the regular cost vs when I have most rendering feats enabled).

Basically turn off everything fancy, and even dynamic shadows if you have to.

Im seeing the same issue on my Mac using HDRP. running very slow and depending on the camera angle the whole scene will go black. I’ve just opened HDRP m for the first time 3 days ago to evaluate it for a new project. So I’ve been mostly downloading unity demos scene but seen the same issue. Any ideas ?

Can you also post your mac specs so we know what we are dealing with?

Edit: I see @francois85 posted some here Frame rate expectations for demo

I found my flickering issues and it was user error. I had a displace map piping into the vertex normals instead of offset

In my case, it’s a full-screen flash, perhaps overexposure as suggested above. But I’ve turned off literally everything I can find to turn off, and it still happens.

@JoeStrout if it really is autoexposure, then it’s probably still enabled. Check Project Settings->HDRP Default Settings and scroll down to Default Volume Profile etc.

Hi, to know if the flickering is due to exposure, you can use fixed exposure and if it doesn’t fliker anymore, it come from this. We have fix an issue for white flash screen and autoexposure in 7.4.0 . But this maybe not what is happening in your scenario.
