Some texture experiments with Baryolax.
This is basically a bunch of low poly spheres, torus, and cubes. Yay textures!
It might just be your lighting. If you think about it logically the detail you see from the hd is a result of shadows created by the modified mesh strong global lighting like in your scene can completely wipe out all those shadows. Below are 2 very quick renders of boris, one with a strong hdr the other with one of my studio setups. The only difference in the 2 renders is lighting. this is why I'm not as big on hdr's in general often the illumination is too global and ends up washing out everything.
I figured out how to get the GISBiosuit to light up in iray :)
..ugh having HDRI issues again. Wanted to use the same night sky HDRI I that I have in the London street scene for a backdrop that would be visible through windows but after loading it in, the entire scene lit up like the Vegas Strip. Using pretty close to the same tone mapping settings as the London scene so I have no idea what is making it is so bright. I tried a test render outside the building and it looks like the map is horribly over exposed. even with the environment intensity and map settings turned down.
You don't accidently have your headlamp on, do you?
Did you try turning the HDRI intensity down in Environment?
...nope and the entire dome is totally washed out even setting the Map to 1 and the environment intensity to .5 like I had it in the London scene. I've been havng to fiddle with settings a lot (unlike in the other scene) to get it to where it looks like it should. I also have the Archetectural Sample truned off as well.
...that's what I've been having to mess with way more than I had to do in the London scene. Finally have it down ot 0.05 for the intensity and .5 for the Map and it looks like it did in the other scene where it is at higher settings.
What Tone Mapping settings are you using?
All the HD is in and the SubD is correct. As far as I know, you can't have SubD if the figure is at base resolution. I changed the camera settings and re-rendered and there is a little more detail now. Maybe it is the HDR and perhaps Iray sun sky is better, I don't have that much experience of either.
CHEERS!
HDRI is 'flat' light unless there is a strong sun element to give a strong lighting source. Even then the shadows are soft and the light source has to be in the right place regarding the figure to get the proper shadowing. Also, if the HDRI settings in environment settings are too high the light will be too harsh and wash out the image.
Yeah. I do see what you mean. I did a render of Darius with the Iray sun sky and it did look more detailed than what I did with that lighting. I think I need to experiment a bit more.
CHEERS!
...ASA 400, f4. speed 1/15th (what I usually used when taking low light photos).
That is what is blowing out the scene. Drop the settings back to let less light into the camera until you get the lighting you want then start to set up the scene and balance the lighting and camera settings to keep it that way. You aren't taking a night scene with the camera you are creating it with the HDRI and the camera.
I see, I'll make some adjustments and redo it and I'll also try one with the sun sky as well. I'm still learning and finding my way, this is only my third week with Iray.
CHEERS!
...OK juist ran into a very annoying error. While running a test render in Iray, I received an Error During Rendering message. Never seen this before. There is no other information what caused it like a memory out of bounds error or anything like that. I am only using CPU mode as I have an old GPU with only 1 GB of memory.
The annoying portion is it seems to have sent the application into an infinte loop after I clicked the 'OK" button, which I cannoit break out of. If I kill the process in Task Manager, I lose everything I did since the last save.
These images are using the same HDRI with just the settings altered for Environment and camera. Lighting is from the HDRI and one distant light.
I used to get that too until I upgraded the graphics driver, I only have CPU too. The log said it was Open GL that was causing it. It always happened if I moved elements around in the viewport to fast, I tend to do that, and Open GL couldn't handle the updating of the screen
It was always when I hadn't saved for a while too.
...well the settings are perfect for the interior lighting I have set up (using the IRay Real Lights) If I drop the settings to allow for less light, then I'll have to mess with the set values for the interior lighting. I only need the HDRI to provide a backdrop that can be seen through the windows to avoid having to add a lot of geometry ot the scene.
I don't understand why the difference in brightness as it looked fine in the previous scene with pretty much the same tone mapping settings and only modest adjustments to the environemnt intensity but at those same settings is washing everything out in this one. That really seems rather incinsistent. Sadly I cannot go to the other scene as the application isstill locked in a perpetual loop amn I'm afraid if I kill the process it might corrupt the entire scene file. For some odd reason there are sevem instances of the Daz psotgre.exe server shown as running in the processes window
The best way to do that, if you don't need the HDRI lighting, is to use the .jpg that came with it, if there is one, as the backdrop. The reason it is so bright is because the inside scene camera is set for the inside lighting, not outside. Take a picture inside the house with the camera set so that the elements inside are visible and the outside through the window will be washed out, set the camera for the outside through the window and the inside will be too dark.
Several instances of postgres.exe is normal, I have seven running ATM too.

Very nice, though with the monitors that bright it's no wonder she needs glasses!
CHEERS!
...for my GPU there really are no new general device drivers to install. All their site has been listing are the "Game Ready" ones for specific game software and I have since I am not a gamer I have none of them. When I did install one of them a while back, it kept giving me blue screens right and left as it wasn't able to find the appropriate application (eg. game programme). After I rolled back to the previous general device driver I was using, the issue went away.
Went to Nvida's site and all the drivers listed for the last couple months are only the "Game Ready" ones and one for Windows 10 with DX 12.
Ended up having to kill the process in TM. Now I have to waste another hour or two setting up all the lights and fiddling around with the environment settings all over again. This has to be a bug in the programme as it hasn't occurred until tonight.
The thing with testing out skin textures and shaders in an empty scene is that once you put your figure in an environment with other objects it isn't going to look the same. Once the light starts bouncing around between objects with shadows, reflections and radiosity colour bleeding, the skin will look completely different. And this seems even more pronounced with PBR.
I often start off with a rough idea of the skin I want to use then do the adustments after the character is set up in the scene. Lost count of the number of times when I think my character looks perfect and then completely different once plonked into my scene. I am making the assumption that you plan to eventually render your character in a scene and not just a portrait. Cheers Fishtales.
Thanks!,Yep, with so big monitors is a need, in fact she reflects some past from me when i was a musician...on 2009.
...unfortunately the normal Daz Backdrop in the Environment Tab is fixed to the camera so the view angle will look off as my rendering camera is a slightly above the interior scene and thus will make it appear that the building is at an angle in relation to to the outside setting. Also you cannot resize or move the backdrop like you can the dome.
Just applied the preview.jpg to the dome and it too is producing ambient light and washing out as well. That should not be happening with the preview image.

I didn't get it either until I started usin Iray instead og 3Delight to render with. Updating the driver worked for me though.
I use Driver Booster to check the drivers on my systems, have done for years.
http://www.iobit.com/en/driver-booster.php
It checks the drivers on your system and then you can let it update them for you. I have never had a problem with it on any of the machines I have used it on.
...other than the NVidia "game ready" ones and the one WIn 10 driver that I already know about and don't need, who else would issue Nvidia GPU drivers? Also, if it were a driver compatibility issue, it should have forced a "stop code" and BSOD which didn't occur.
Like I mentioned, I never saw this error message since I started in this years ago and for a long time I was using the old Intel integrated chipset on my 32 bit notebook which wasn't supported with service/driver updates for years.
It is Intel Graphics on this laptop and Samsung haven't updated their drivers in years but I went to the Intel site and, eventually after weeks of trying, managed to get the laptop to accept the Intel driver and it has been fine since. It is an Nvidia card that is in the tower, 256 MB, and there is a program from Nvidia that checks for any updated drivers which I haven't used in years. There must be updates to the generic drivers too somewhere on the Nvidia site.
