Problem solved :D

Even though im still not sure why the gamma/lut causes problems. It seems to be possible to fix it by setting all materials when loaded to a custom gamma of 1.0 Whether that is a rule of thumb or only if you are using jpgs i don't know. But if anyone can explain it, i would appreciate it as its always good to know why you have to do something :D

But here is a Poser render with 10% intensity and no Gamma correction.

I tried to render it again without ambient occlusion and with the light invisible. It have no effect it looks exactly as the image above. However I tried to recreate the scene in 3ds max as best i could, converting the scene 1 to 1 is not easy as it uses some other settings. But I tried to match the camera view as best as I could and added a single photometric point light approximately where it is in Poser scene. This turned out to be quite interesting i think and beyond my technical understanding of how these things works, but hopefully someone with such knowledge or idea can help explain it.

Since these photometric lights works differently than those in Poser, I made the light at 750 cd intensity which will be equal to the 100% intensity in Poser. Also all images are rendered for 4 minutes.

Light intensity of 100%

Light intensity of 50%

Light intensity 10%

Light intensity 1%

I think its pretty clear that the light is much more natural, the reflection seem to match the intensity of the light. So at first I thought that this is a problem with Poser then. But to be honest, it took me quite a long time to get the light looking correctly.

This is a render with the exact same lighting and everything as the 10% intensity image above, Only differences between them is that i turned off Gamma/lut correction in 3ds max, the same option you have in Poser render settings for Firefly, but not for Superfly so I cant test it in Poser.

But if you compare the Poser renders with this image, despite that the lighting works a bit different. They share the same weird hotspot, but also compare the noise between the 10% 3ds max renders without the gamma correction and this one, both of them have rendered for 4 min which can be setup in max. Its really weird that the difference is so severe. Can anyone explain what is going on here? Why does Gamma/Lut correction have such huge impact on render quality in PBRs and is there a way to turn it off for Superfly so I can test it there?

Is it possible that you have an infinite light on? Are you using IDL or IBL lighting setup?

Dammit, noticed the window was a little misplaced :D So ignore that. However the reflection on the machine is still the same. But the point light is the only light in the scene, and uses these settings..

Here is the 10% intensity with corrected window just so you can see what to ignore.

| These are some great observations! Thank you for sharing them with us!! |

Unfortunately, I had hooked up the roughness map wrong in the test...Dohh!! :D However guess it could help someone that experience such issue, that it could be due to their roughness map being wrong.

| How did you reverse the roughness map? |

I just copy pasted the tile map and switch around the black and white tiles. However just to be clear it doesn't mean that the roughness map should always be inverted, it was just in my test. The more rough you want a surface to be, the more white it has to be in the roughness map, so 100% roughness equal white and 0% roughness is black.

However this test did little to solve the noise problem as it seems to come from somewhere else. So I now suspect that its the lights themselves in Poser. So did some more testing, that hopefully ain't flawed :D

This is from the actual scene where im testing. There is one point light placed a little bit underneath the ceiling (Hotpot in the ceiling shows approximately where)

First image have 100% intensity and looks sort of what you would expect with such bright light. There are a little noise but its rendered at 10 Pixel samples.

Second image is at 50% intensity, still looks somewhat ok, however some problems starts to occur i think.

Third image is at 10% intensity, now i think some problems really starts to show. Looking at the ceiling and the floor the light is very dim. However the edge of the window is still very lit and the reflection on the machine to the right looks like its a 9000 Watt light bulb hanging there and doesn't seems to really match the amount of light that is on the floor or even the ceiling to which the light is much closer to.

Fourth image the intensity is 1%, still the window is very bright compared to the intensity of the light and even though the reflection in the machine is not as bright it still seems to bright, i think.

To me it seems as if the light intensity falloff is some what off when it comes to reflections or is it just me?

Did some more testing and it seems you have to reverse the roughness map. :)

So are these like the ones Dubfx uses, if you don't know him here is a video? :D

Sure no problem, there is probably some more fancy way to do it, that I don't know off.

Not sure this is what you are looking for, but maybe it will work for what you need.

But what you can do is to make a box primitive and scale it down so it rather small, just so its easier to see what is going on, then you place the box at the toes of where you want the pivot to be. Then select the character and go to Figure -> Set figure parent.. and select the box, now you can rotate the box and make the character pivot around it. There might be some more fancy way to do it, but im not sure how.

This is how you could do it using just Poser:

So it basically just boxes that you scale so they have the correct dimensions and you move them into position. If you use a modelling tools like blender or 3ds max you can do it even faster and weld the boxes together and so forth, but in principle its the same.

Now when you place the camera inside you have to be sure of two things:

1. All your lights use ray tracing for shadow casting, so just go through each light and change those that ain't

2. Make sure that you use a render quality that uses ray tracing in the Firefly render options. (The slider thing, need to be set so there is a check mark in the ray tracing)

Think it might be related to the infinite lights, try to turn them into point lights and move them outside the ordinary box and in the firefly settings turn up the render quality so ray tracing is enabled then it renders fine for me at least. But as I said its a lot of work for something you could solve simply by using boxes :)

Not sure exactly what is wrong, I would however fix it by making solid mesh objects instead of flipped ones, like this:

Simply to avoid these kind of problems, so if you need a room always model it like its a wall with thickness or make sure that if its a plane, that the normal is always facing the camera. Whether its Poser not being able to handle flipped normals correctly or something, it at least to me is far less problems and faster to simply model the wall in form of a box rather than a flipped one and trying to figure out why it doesn't render correctly :D.

You can also try to share the scene, if it only contains the cube you made

Did you place the box above the floor in the model? You don't have to be very precise just make sure it above the floor in the model and so it covers the area where the light poke through?

For your Superfly settings, I would suggest the following changes, not that i think it will solve anything, but just as general settings:

Pixel samples: 8 (Will be ok for quick preview renders)

Progressive refinement: Turn that on (Not sure why you would ever render without it on, maybe someone with better knowledge of Superfly can explain why? :))

Max Bounces: 4 (You need that to render glass correctly from what i can see)

You might or might not be able to increase render speeds by enable or disable "Seperate process" in the settings under render. But you will have to test out what works best for you.

Leave the rest of the options to whatever you want, seem to have no impact on render speed or quality from what i can see, tried to put 512 in them which made absolutely no different. If you want to increase quality just increase pixel sample (23 should give you rather good quality).

Always use render region when testing, no need to render the whole image, just mark the area that you are interested in, will be a lot faster.

But then again im not an expert in Superfly so someone will most likely correct me and maybe it have something to do with materials or something, the information about Superfly is really lacking unfortunately. So these settings are just what i found to be working well. :)

Are the mesh (Wall and floor) one object? maybe the floor is lower than the walls just slightly. Also you can try to add a plane or box as a test floor and let it overlap the walls just slightly and see if that stops it, just to see if its the model or Poser. Its a bit difficult to see what is going on. Maybe if you make a close up render of the door and wall in the background and do a wireframe view as well. Just do so you show the wireframe view (Ctrl+3, or third option in document display style) in the viewport and take a screenshot using printscreen.

From what you describe it should be correct and working. Can you try to show some screenshots of the scene, settings, Poser version etc. Might be easier to figure out what might be wrong.
