Same Material Same Properties - Different Display in PBR

Yes great tip but why do material behave this way and how would anyone guess at this behavior?

I don't have access to the program right now, but if you create a block of that material outdoors and the same one indoors, not connected to each other, what happens? Do you still get that glowing effect on the outdoor one?

 

 

Reference this post for example of material ID:

 

If I were to build a very basic and light weight Phys-based rendering engine I would use Material and Object ID's. The material Id would be associated with the material being applied to an object, and an object ID would be associated with the all polygon faces of the object as a collector. 

The simple explanation is that any light source that an object ID comes in contact with will effect the material ID associated with it. 

The crucial part of this to have a greater success rate with the engine is to make sure your joinery is sealed...I would encourage learning the auto build roofs in and out...Solver is a wiz at this sort of thing

Very basic and lightweight huh?

The problem you're seeing with the beams is due to light leaks from the wall to roof connections. This convo just brought up a question I've been meaning to ask, so thank you. About to start another post regarding roofs

Makes sense in my case. The particular project I worked on that had this issue, I used manual roofs; things may/may not have joined up property, creating leakage...

For me , I have replaced some of my older materials with the new materials of the same kind b/c I know Chief has been adding new materials in X10. If you haven't re-vamped your template plans lately, might be a good idea. Not sure if this will help you , but it can't hurt.

Tried those simple changes and the beams were still light blue. No doubt your suggestions have merit but it's a bit stupid to have to deal with 'light leaks' and other anomalies when using PBR. It should just work without having to lower the sun for an 'interior' PBR view or turn down the sun to 100 because the sun affects the display of material 'inside' the building. I assume Chief is working on these issues

 

I am with Larry on this.  I design houses, not a lighting specialist for renders.  I have a glowing casing on one door in the same room as another.  UGH@!  There is a roof, there isn't any "sun" coming into this bath, two exact doors.. but one the casing glows, the other doesn't.  I just want to PBR without having to spend more than 10 minutes trying to figure this out.  Deadlines to meet.. going to Raytrace.  

 

Before I submitted the above, I tried one more thing.. I turned the sunlight off.. and it fixed the issue (kinda).  WHY???? Like I mentioned, there isn't any natural light in this room, so?

 

Since I hadn't heard much on X11..  is the PBR getting these issues fixed?

Looks to me as if the bright white door casing might have emissive set in the material properties.

That would make sense if it was a different door.  But it is an exact copy of the door to the left, just a switch of the hinge side.  And I used this door throughout house (in 11 different  bathrooms with different lighting), and this is the only room it does this in.  I fixed though by toggling sunlight.   

 

Thanks for your input Graham.  I was reading through this forum last night for a solution, so many tricks and settings that everyone suggest..  was mind boggling and a lot of "huh's?

Always best to post the Plan in these situations, then people wouldn't need to guess, I am sure Graham would of looked at it for you for example....
