Why do my lights never change!

dcooper001_62def9169a

I am having problems with lighting in DAZ Studio 4.10 and 4.11 beta. I recently set up a figure and put two infinite lights in the scene and rendered in IRAY. Now I can change figures, lights and movement and I am getting the same light setup all the time. No matter what I do the lights stay the same. I am rendering in Iray.

Please Help

In the Editor tab of Render Settings is the Environment Mode set to Scene Only? If you still have the Dome contributing it may be swamping the effect of the Scene lights, assuming you have Dome and Scene rather than Done Only or Sun/Sky, selected.

Just a shot in that dark, are you adding a camera to the scene to render through, then making sure in the camera settings that headlamp is off?

Richard Haseltine

Adding Distant Lights would turn the headlamp off, unless it had been deliberately turned on in the camera.

Just have distant lights in scene. Even if I add new lights the render comes out with the same lights and direction. I can move the lights and the figure in the scene and still the sa lights and direction.

But what is the setting for Environment mode in Render Settings? That isn't something you see in the scene, it's a setting for rendering.

The setting is default, but have tried just scene and the dome and scene and dome only with the same results. I can start a new scene with any figure and put lighting in and I still come out with the same stuck lighting in the render!

Richard Haseltine

Scene only should show the effects of adding/removing lights. Please do a test with a simple scene - just a sphere sitting on a plane (Create>New Primitive) and post the results with a couple of different light set-ups.

Two different light setups same results!

Not quite - if you layer one over the othe and set the blend mode to difference (where pixels that are identical on both layers will be black) then apply a levels adjustment to bring out the near bu not quite black areas you will see that there is some variation. The problem is that you still have the dome on - you can see its reflection in the spheres - and that is swamping the local lights you added to the scene. Of course you will then need to adjust the Tone Mapping section of Render Settings, since these lights are so much fanter than the HDR dome.

Tried everything so far I get the same stuck lighting or I get a black figure in scene only with lighting. Help

Black figure would be where you need to adjust the tone mapping options in Render Settings - by comparison with the dfault HDR even a distant light is quite dim.

If you're adding only your own lights, have you 1) tried using light presets from other products? 2) Could you include scene files, of the ones with your own lights, with your setups to look at? Including the spheres is fine. Are you saying when you replace the sphere with a figure it renders black? We can try adding a figure to your scene to test it.

OP: what is the Luminance of your added lights? If the luminance is at default, 1500, it is way too low to have much effect, especially if also are using a hdri/exr for lighting. I generally have to crank it up to around 15-25000, for them contribute to the render. Doesn't matter the light type. One more thing to check is where is the light? If using distant lights, but loading Apply default settings, in the pop up will load the light at an extremely low angle and result in almost no contribution to the render. Switch your view from the drop down in the upper right corner of the Viewport to DistantLight 1 for instance, to see where the light is relative to your object.

Solved the issue thanks for the help.
