    as for colour temp (Kelvin Scale) I remember years ago when fluorescent tubes were the norm, 55 (5500K) was spouted to be likened to daylight. In fact they used to refer to 55 tubes as daylight tubes. Yeah I used to work in Electrical Wholesaling and we specialized in all sorts of lighting, from fluro tubes to stadium lighting so all this is coming back to me in a flood.

    Yes, they were sought after as grow lights before grow lights became common place, for those in the know, especially people growing their own Japanse Split Leaf Maple trees. ;)

    They use a mix of Sodiums and Metal Halides now Gedd. That's progress for you.

    Well, it doesn't save. :( But at least if you hop between cameras or other views, the thing doesn't turn back on. I'm thinking of creating a scene file with it turned off and you can set Studio to load a scene on open and also to load a scene on new. Once I figure out what I want in this scene, I'll most likely create it and use it and forget the headlamp. :)

    I have a scene set up under new and at startup, that includes a default camera and a pointlight that is invisible. (Which turns off the headlamp, regardless of which camera you are using.) This makes it easy to use the headlamp if I want to, or not. The difficulty is I have to hit CTRL-L if I am not using Iray preview mode. It is all a tradeoff, so pick what works best for you.  

    The key is, when you pick your default scene, once you save a default load scene, browse to it using your file browser, ungzip it, and put it into a text editor. Remove the authorship information and resave it. (You can gzip it again if you wish.) This way you won't save over it by mistake.

    TRICKS! about Sun/Sky system.

    ... you need to think outside the box.

    Interesting. I haven't tried any poking at the Sun/Sky settings yet, maybe it's time I tried.

    Can anyone tell me why I'm always getting Iray renders on a transparent background?

    I tried setting the Environment pane to 'Backdrop' with a light gray background, and it worked for a few days, but has now stopped working. (Also, this resets to the default white color with every new scene, so it's a total pain)

    All I want to do is render on a gray background and keep those settings for every new scene. Is that so difficult?

    Yeah, I hear they even invented something called the 'personal computer' and 'Internet' since then. ;p

    That sounds like it should do it, but I tried and when I re-opened DS, the Environment pane had reset to None. when I set it to Backdrop, the color was back to the default white.

    I'm going to d/l the latest 4.8 and see if anything's better. I'm having some weird issues with this one (4.8.0.55), like copy/paste on materials not working.

    Kerya,

    I already tried making a default scene with a couple of props in it. What happens is I open DS, hit CTRL+N, and it asks me if I want to save the changes. Since I haven't touched anything, I don't know what these changes are, but it's almost as annoying as playing with the Environment pane. LOL.

    If you do that, then the background will be ignored on load of your default scene. (Whether it is on New or on Startup.)

    Spooky,

    I've tried it both ways and when I re-open DS, Environment is always reset to None. I set it to Backdrop and the color is back to default white.

    Edit - I'm d/ling 4.8.0.59 now. Maybe it's been fixed in the newer version (And maybe copy/paste materials works every time!)

    In Preferences if you make sure you have Record Background color and Record Background image checked. Make sure you have ignore background color/image on load unchecked. (See image.)

    Then set up your default scene and save it. Open the default scene in a text editor (after extracting it using soemthing that understands gzip) and remove the authorship information and resave. (Compress if you want.) 

    Now in Preferences set it to load this scene on both new and on startup. 

    That should give you what you are looking for.

    Note the reason to delete the authorship information is to keep the scene from accidentally getting overwritten. If the author is not you, then Save is treated as Save as. 

  • macleanmaclean Posts: 2,438

    Those are the options I already have checked.

    Isn't there a way to do it without having a default startup scene? Because the default scene I used before kept asking me if I wanted to save the changes when I hit CTRL+N

  • DAZ_SpookyDAZ_Spooky Posts: 3,100

    By default, the background is blank and transparent. If you don't load a scene it loads the default. While changing that behavior (to use background settings from last session for example) makes for a feature request, it isn't current behavior. 

  • macleanmaclean Posts: 2,438

    Ok. Thanks Spooky.

    It really should be a current option. It's a pretty radical change from previous UIs

    Fixing the alpha background bug and the need to seperate the background color from the viewport color required the initial change. (Part of the 4.7.0.12 release, IIRC.) 

     

    Please submit a feature request. 

  • macleanmaclean Posts: 2,438

    Spooky,

    I installed 4.8.0.59 and created a startup scene as you suggested. That works for opening DS, but as soon as I hit CTRL+N for a new scene, everything reverts to default. So it's not really a great option.

    Sorry, but I won't submit a feature request. I did try accessing the bug tracker, but got an Untrusted warning from Firefox. Anyway, I've done more than my share of tests/requests in the past. for now, I'll just put up with it and/or keep using DS3.

    There are two places to add the scene one is for DS Startup, which is where you put it, and the other is for new scene, on the scene tab under preferences. 

     

    http://www.daz3d.com/help/help-contact-us/ and hitting the green submit button gave you an untrusted warning?

    The old bug tracker link http://www.daz3d.com/bugs/  may give some people a cert warning because it rediredts to a zendesk domain.  The link on the Contact us page is a direct link...to the same place, but not a redirect, so no warning.

    Brill!

    Also a good illustration of why tone mapping isn't sufficient for everything. You need the high luminance to show the backlight.

    BTW quoting is kinda weird and I had to fake it, sorry.

    Whew! Finally read this from front to back. Definitely worth doing if anyone is interested in iray and hasn't yet. I got a ton of notes out of it!

    and I think you are missing this step:

    M Busch,

     

    No, I didn't miss those steps. I removed the authorship info and had all the same options checked.

    But . . . when I went back now to double-check everything, I saw an option in Preferences> Scene I hadn't noticed before - On New> Load File. I set this to my startup scene, and now when I create a new scene, I get my startup.

    So, you've solved the problem for me - even if it wasn't the issue you thought it was.

    Thanks!
