[SOLVED] No iray preview in viewport after 4.14 General Release

StratDragon

SOLVED

After downgrading the driver for the GPU (256.71), then reinstalling the drivers (457.30), creating new scenes instead of loading previous ones; all which failed I added a primitive and the viewport rendered it.Once I deleted the primitive the scene remained functional in the Iray viewport. I tried to report in the bug submission but it repeatedly fails.

On a related note I have moved to an area where broadband is not available and I'm continuously throttled by the sole service prodvider in the area down dial-up speed so downloading can take substantial time.

 

Original Post:

After upgrading to 4.14.0.8 I can no longer see a preview of my scene when switching to NVIIDA Iray in the veiwport

I keep getting logged out when I try to edit my sig buy specs are
Windows 10, 64GB RAM, 2x3.06GHz 6 Core Xeon CPU(s), MSI Nvidia 1660Ti 6GB DDR6. NVIDIA Driver 457.30

steps:
load figure
select NVIDIA Iray from the dropdown

Expected result
Iray preview of rendering

Actual result:
gray, textureless scene

Steps taken:
reset Iray engine to default from Render Setting Pane
rebooted.

result:
no change, still doesn't work.

what am I doing wrong? what do I need to do to make this work again?

I'm new to all of this, but check your Drawing tab and make sure it's set back to Iray instead of something else.
