PBR help - foggy windows

Hey there,

 

Since PBR is now an option for me I started messing with it.

The main problem is my windows seem opaque and are casting a fog like glow in the room.

I'm sure it's something dumb.

Here's the plan and an image...

ah okay...this largely has to do with the material properties of the flooring. You could do well with a material that has some movement in the roughness map to breack that up

Ah ok, thanks. 
 

The floor material is from the modern contemporary style palette. 
I assumed those materials would be fine tuned for pbr?

Rene and Alan are probably away ahead of me, but that kind of looks like glare, and that the external lighting (daylight) is set way too high.  Try reducing the sun intensity for a start as Alan is indicating in his render settings.

I reduced the daylight quite a bit and that did help but I'm still getting the fogginess. 

 

Anyone know why Preferences is showing 0MB for video memory?

In settings Uncheck Opaque Window Glass and that should solve that

I have Opaque Windows unchecked. 
 

I know it looks like it’s checked.  That’s why I’m sure it’s something minor tha I am missing. 
 

The glass is clear in Standard render, but milky in PBR.

In Physically Based rendering mode, you have "Use Backdrop Image" unchecked:

However, checking it produces a lot of other unwanted effects. Firstly, since you have no interior lights, the blue backdrop is washing everything inside the room with a strong blue color. I played around with Sun and Daytime Backdrop Intensity settings and added a bunch of interior lights and quickly got this, but it still needs a lot of work (which is why I don't mess with PBR, I'm much better with CPU Ray Trace):

Also, your glass material is from the Clopay garage door Manufacturers catalog...? I changed it to Chief Standard Glass in one sash, but they look the same...

That refers to the memory on a standalone graphics card. Since newer Macs like yours use integrated video that shares memory with the CPU, there is no onboard graphics card hence no memory on the non-existent graphics card.

Thank you Chris!

 

I will follow your tips on adding interior lights and adjusting outside sun.

 

I usually use Raytrace but I was hoping on using PBR when zooming around with clients in 3D.

 

been an ssa user since X6 and still struggle with a few things.

I did not spend a lot of time on this scene. I even forgot ot bump down the backdrop intensity. My sun intensity is set to 500. I have the lights you see on the ceiling and one additional light placed close to the coffee table that is at 2500.

Youre missing the part where he can't use ray tracing :)
Also cap your samples and kick em down to like 50
Also turning sun to 500 is not neccessary, kind've a crutch really, depends on what you are trying to do

You can do alright with regular pbr. Needs a lil post processing though, a filter and some fake ies lights

That’s incredible. Do you mind if I use that?
 

I’m assuming you couldn’t get clear glass either? With regular pbr, that is?
You used the window as a mask for that outside image? (Photoshop)
 

great work. I need to put more time into photoshop. I’m sure with your level of skill that was a 10 minute PS job, am I right?
