    Here i am again with yet another noob luxrender question :cheese: (Maybe we should have a LuxRender subforum here at Daz ?)

    How do i change the intensity of a sun light ? Part of my scene is overexposed, but changing intensity or gain seems to have no effect.

    Excuse me - where did you get 4.5.0.90??? The newest version is 4.5.1.56 ...

    4.5.1.56 is newer then 4.5.0.90

    ... only mentioning because the way you worded your comment looks like you might think the reverse is the case.

    Some advice for everyone, If you are going to set up a render and go t bed while it renders, make sure you have set frigging windows update to OFF! Or at least set it so that you choose when updates are installed and not windows......... I lost 8 hours of rendering and woke up to a rebooted computer and no render to show for it.

    Came to the same conclusion when i woke up this morning... :lol:

    Edit : there still might be an image in your temp directory (appdata/roaming/daz 3d/studio4/temp)

    I have windows update turned off for that very reason! However a few days ago, we had a couple power outs due to a fire in the city.... over night the power went off. I got up in the morning and it was off. T_T so restarted the render.....

    power went off again :(

    However the render i was trying to render today won't render via lux. error every time. Something's not working.

    Thanks for the link but no dice, a couple of other renders were there but not the one I was doing last night... Oh well I DID have a load of stuff in the scene that is not in the render pane so it probably was taking a stupid amount of time to render anyway. Ill just go back and hide everything not in the render.

    Pat of the scene or a perticular surface? If you are adjusting your sunlight and only part of the scene is still overexposed it might be the surfaces or it could be the Kernal settings

    When you render an outdoor scene you can try to light it using only "Sun"
    In the Lux Render interface Set your Kernel to Linear
    Sensitivity 100
    Exposure 1/125
    FStop 16
    Gamma (anywhere from 2.1 to 2.8)

    As long as you are not using multiple light sources this is the general rule for outdoor photographers to get optimal shots.

    Luxrender should have the option of creating an FLM file that can be used to "pick up" the render where it left off. While that does save your scene in progress you need to be ware that your power settings can stop LuxRender dead in it's tracks. I turn "put computer to sleep" off.
    Get used to keeping your computer on over night and make sure airflow and dust bunnies are down to a minimum. Most applications you use will never max out your CPU for sustained periods of time, but LuxRender will. Warm rooms, poor ventilation and space heaters will make a CPU act like it just got hold of some funny tasting brownies at a Jefferson Airplane Concert (e.g. Heat+CPU=BAD)

    Is there an actual error message - on screen or in a log? Without that it's going to be really hard to diagnose or help.

    Part of the scene, where the sunlight hits the surfaces the hardest, like it would in a photograph.
    The sunlight shines through the window, and i set the ceiling to a surface light, but i can't find a way to control the light intensity. Setting the sunlight to 50% gives me exact the same result as setting it to 150%.
    I had a similar problem with an outdoors night scene, it is always bright like daylight.

    Looks like it is the skin - the leotard isn't whiteout.

    *searches in her Luxus tips file*
    Does this help?

    You probably want you URoughness and your VRoughness at around 0.8. Your skin is so smooth it is reflecting like a mirror.
    The roughness parameter does not solve the issue, but I removed the bump map and this worked. So I set the bump map again, but at a very lower value and the problem gone away. Much better now…

    Ok, that's confusing me. :) Removing the bump map to make the skin less smooth ? Tried it, but it doesn't make a difference.
    Added all Lux parameters to the skin and set RoughnessU and RoughnessV of both glossy and glossy-translucent to 0.8, again no difference.
    If i had the same problem with my camera i'd think the lightmeter was stuck on auto.

    And there's no way to dial down the sunlight a bit ?

    Edit : trying StratDragon's tips now...

    Now i'm getting somewhere. Setting the kernel to linear sort of turns LuxRender into a DSLR. That's good, i'm familiar with that. I can compensate the loss of light with my surface light.
    And if i have multiple light sources i can use gain or light importance to control them relative to each other ?

    I think i just made a step forward in understanding Lux, thanks everyone !!

    Anyone having problems with spot render in Luxus? My spot renders are completely off centre (see attached). Was quite happy using Reality, but the spot render function was what sold it to me - however its not working as it should.

    That's not good. In the RenderSettings, do you have anything in your Extra Settings?

    That is odd. It looks like your render cam may not be the same as your viewport camera. Are you using an orthographic view in your view port and a different camera to render?

    Actually I tried spot render, but since I had gui set in my render preferences, it popped the section to be render in the Luxrender gui.

    Just a standard camera - think I will reboot and see if it does the same thing.

    Still having the same issue - have uninstall, re-installed, rebooted and to no avail. Think I may have to switch back to Reality and ask for my money back. Nothing is ever simple is it?! Lol.

    At first I thought it may be that because you render window is narrower that your viewport, but that is working for me. I am kind of stumped. I am certainly willing to work with you to get it resolved. PM me if you want.

    Thanks, I probably will. Will try a few things first to see if I can get it resolved without stealing your time.

    Everything I try with the lights is not working, it always comes out as high noon no matter what I try.

    Anyone got a Luxus lighting for dummies? You know simple explanations with pictures for those of us who just can’t seem to get it.

    Thanks
