Can you turn off the wireframe on lights. [Solved]

Hi, 

can you turn off the wireframe on lights? See photo. I'm happy seeing the sphere but the white wireframe is of no use in general. 

 

Thanks

You could scale the light down, which might help. However, the wireframe avatar itself cannot be turned off itself - though in the 4.11 Public beta there is a display button for Visible in Preview, not sure if that helps or not here (and can't check just now).

Thanks Richard, I tried scaling the light but that scales the sphere I didn't try scaling down the size of the light then scaling back up the size of the sphere. My computer crashed on me and I hadn't saved the scene. I'm setting it back up to test it. I'll get back. 

Thanks

Thanks Richard, Yeah, scaling up the sphere and scaling down the light so the sphere size is the same does the trick. Thanks. I'm not used to having preview set to NVIDIA Iray, so I've been missing a lot of subtleties in changes. 

 

 By the way, what is the point in Shadow Type being set to 'None'? I'd never considered it before. I took it for granted that the light would not pass through 'solid' objects like humans. Well, I'll have to remember to always set my lights to Deep Shadow or Retraced. 

Thanks

Shadow Type : None, etc, is a 3Delight setting. Maybe your lights aren't in Photometric Mode? If so, you're not getting the correct Iray settings.

Oh, perhaps I missunderstood another forum entry or maybe that was wrong. I turned photometrics off. I'm doing a quick render at the moment, when it's finished I'll check. 

 

Thanks.

Iray will always cast sahdows in Photoreal mode (in Render Settings). Interactive Mode does allow non-sahdowing lights, but a high price as it disables a fair number of other features.

One of the more annoying things (for me) is that the wireframe that Daz displays for spotlights (including the “cone”) bears no resemblance to the actual shape of the light as set in the properties. If you set the spotlight to be a rectangle and size the rectangle up, the cone is still circular, and the wireframe doesn’t reflect the size you set.  Makes setting up certain kinds of lighting a pain  (“Look thru the the light” has the same problem.)

Filed an enhancement request on this quite a while ago, but I guess it’s been File 13’d. 

Sigh.

No, I had Photometrics on, it doesn't seem to make much difference on or off in the preview iray render.

I'll keep it on anyway. 

Thanks

if you see options for shadow type, deep shadows, or ray traced, you need to set the render engine to Iray. Those are all for 3DL.

Yeah, you're right it was in interactive mode though I was set to Iray though. I'm on a Mac if that makes any difference. It must have happened when I had to reinstall or when it crashed. I hadn't noticed. Thanks, also to rames and Richard.

Photometric simply means the spotlight, point, or distant light willproduce lighting effects in line with the perception of human vision, which is centered around about 550 nanometers (yellow-green). This is because the green receptors in our eyes are the most sensitive (related, maybe, to the color of edible plants?) Since luminosity and color balance are aspects of the related physics, turning photometric on or off only hides or displays these features. It has nothing to do with shadows, falloff, or any other realworld simulation of lighting. 

As noted above, if you are using Iray and wish to control shadows you can use Interactive mode, which kicks in some biased features inside Iray. The results are, naturally, not as photorealistic, but they can still be pleasing There are also limitations as to the number of lights that can be displayed, and some other things. 

The preview lights are only for general modeling. Have you done any photography with flash? Professional units have a low-output "model light" built in. You use it to aim the light, since the flash isn't on long enough to see what it might look like. Use the previww mode by turning on one light at a time and getting a notion of how each light models the subject. You will only be able to see the true influence of all the lights when you render.
