KuJ Alchemy Lab - Lighting?

Blando Calrissian

Well, you always come across something new, right? 

I picked up the KuJ Alchemy Lab recently and, while it looks pretty cool (I love the props!), when I hit the "render" button it was like setting off an atomic bomb. The Environmental and Tone Mapper settings don't seem to be that far off compared to baseline- and changing them doesn't seem to help anyway. It's not the cameras, either; rendering through the perspective view creates the same whiteout conditions.

Even with all of the camera headlamps off, the candle in the scene 'snuffed' and turned off, all of the settings restored to factory originals, and setting it to "Scene Only," the render is still far too exposed. I'm baffled.

Any ideas?

Ah, that would do it! No, I have not made the switch. Is there anything that can be done? Do I have to track down every emissive and adjust?

install the latest beta so can use either build as all stuff released since Nvidia removed that functionally will have this issue for you 

I am curious though with a RTX3060 why you are not using the current build

Looks like your Shutter Speed and ISO are too high. There is definitely light coming from somewhere in that scene. Raise the Shutter Speed to 256 and drop the ISO to 100 and try a render.

BTW I knew because I got exactly the same result with D|S4.11 which I use with my GTX980Ti because later added RTX functionally in iray adds a Gigabyte of VRAM to GTX cards

the Beta renders correctly and instancify by Code66 reduced it sufficiently to fit on my card without going to CPU

Sadly, even when you drop everything to stock levels, you go from white-out to yellow-out. I can confirm that all of the candle lighting is cranked up to 500-600 kcd and the ghost lights to 200000000.0 kcd, which is more than enough to blow out the scene. Turning down all of the candles and flames to 300cd, restoring the Environmental and TM settings to norms, and turning off the ghost lights returned the lighting situation to normal (that is, 4.15 normal)

There looks like a blindingly strong light coming from the left that is throwing off your settings.

It's a bit of an optical illusion, coupled with the light coming from the candles on the floor just out of view. Even the candles on the table are throwing out immense amounts of light because they are all set up for 4.20 instead of 4.15.

I was given a 2080Ti and this scene renders perfectly as is in realtime on the latest beta 

fluff around all you like on your earlier build, I will be finally upgrading my production build now

I'm going by the chair shadow on the wall and the light is way too bright for that scene.
