Vray HDRI rotation lag

[danliamcorris]

This issue has been brought up before, but I just thought if anyone had come up with a solution. We upgraded to 2018 and now 2019, yet the issue still persists.

The problem occurs when rotating a vrayHDRI material that is displayed in the view port background horizontally. Max locks up for 10-15 seconds every time you adjust. This even occurs when a HDRI's rotation is linked to that of a VrayDome light. Rotating the light gizmo produces the same lag. Lowering background/environment texture quality does nothing to help.

3ds max 2016, had no problems at all with the same set of HDRI files.

We've upgraded Vray and Max the past few months, so I'm not sure which one is causing the issue but I'm leaning towards the 3ds max update.

Any ideas?

Has anyone else encountered this issue? Some comment from Autodesk staff perhaps? It's been an issue since 2016. I've posted a similar question on the Chaos Group forums.

Hi,

There is a workaround for this,

And that is changing the graphic mode to Legacy Direct3D,

Of course you'll need to restart Max for it to take effect,

It worked for me, even with an HDRI of more than 350 MB, the rotation was smooth.

Not an ideal workaround, but thanks for this!

I have the same problem. I wonder why do you say it is not eh right workaround. Do we loose any functionality switching from legacy to direct 3d?

Hi,

Switching to Legacy 3D will just make you lose some advanced display features,

But when it comes to production nothing will change. So no worry.

For example of things, you will lose, the High Quality display mode,  the Per-View preferences, Stylized, etc,...

It's like you're few versions back when it comes to Display features.
