Dome light looks super low res when piped through a colour correct

[seandunderdale]

dome light texture looks great normally, but when you out it through a maya colour correct node, it crushes the quality. Is there a way to fix this that Ive missed?

Doesn't seem to happen on my end. Could you attach the scene here? Also, which V-Ray build do you have installed?

Sorry, I should mention its a viewport issue, not a render issue.

Im on Maya 2022.4
V-Ray 5 for Maya, update 2.2

(v5.20.02, revision 31334 from Mar 31 2022)

Confirmed here too, HSV also producess blurry HDRI in viewport.

The issue is reproducible. Thanks for the report. I've logged it (internal bug-tracker id: VMAYA-11587) for dev investigation.

In V-Ray 6 for Maya, hotfix 1 you can find improvement in the viewport resolution of VRayDomeLight when texture goes through intermediate nodes. The resolution is affected by viewport shader quality presets in V-Ray Settings->Settings->V-Ray UI. After changing the preset you should click on "Toggle pausing viewport 2 display update" which will refresh the texture and change the resolution. We have logged an additional issue (internal bug-tracker id: VMAYA-11734) to make it update automatically after changing the preset.

I had to desaturate a HDR ( since ACES blue skies turn really Cyan in viewport)... and noticed that this blurry effect is not fixed in VRAY 5 latest build when piping any color correction node to VrayDome. This request is quite old already, any update on this or bump priority?
Thanks

This has been fixed for V-Ray 5 since stable nightly 31946 from 07.03.

Hi Neli, thanks for the update, unfortunately I just grabbed the latest build this morning and the Dome is still blurry.
The viewport clamp texture resolution is off, I've loaded an 8K hdr in the dome texture and it shows crispy, but then I use a Maya HSV node and the image is blurred out as before. The vray color correction doesn't even show the image at all if plugged into texture.
Please see the images I just tested.Maya 2033.3 Windows 11 RTX4070

Also I followed your suggestion Vray UI>Viewport shader quality and set it to "HIGH" (which is still different from Vray6)...and that had no effect , also tried and refreshed the file swatch and HDR still blurry.
The Vray color correction node also still displays the entire Viewport as grey, is this node not supported or supposed to be connected to a Dome?

Any new developments on this?...still blurry latest build Vray 5

The issue is fixed, however, the result will not be identical to the non-CC HDRI (because it may get too slow). We've increased the baking resolution of the HDRI, which is now controlled through the Viewport Shader Quality parameter (Render Settings > Settings > VRay UI). To update - use the "Toggle pausing Viewport 2 display update" (pause button near the render settings/hypershade/layer buttons). We'll see if we can add a "Full" option for future releases, though.

Otherwise, the grey background issue (internal bug-tracker id: VMAYA-11978 ) is fixed in V-Ray 6, however, it's not yet picked for V-Ray 5.

Okay, hopefully it will be addressed for an upcoming Vray 5 build.
thank you for the update.

The grey background issue should be fixed in the latest V-Ray 5 nightlies.
