Subject: Creating rotating lights on object


hamiltonpl ( ) posted Mon, 12 November 2007 at 1:37 PM · edited Mon, 23 December 2024 at 2:20 PM

Is there a way to PARENT a light to an object? I want to parent 3 lights equidistant from each other, attach them to an object (in Poser you "Parent") so that I can rotate the object and create lights that spin.  This is for a spaceship effect.

I have VUE Esprit and I've looked but am not seeing a way to do this other than animating each spot light separately  which would be a huge pain. Thoughts?

You should be able to do this using "Link to".  Create your lights and your object.  Select all three light and in the tabs at the top right you want to select the third tab "Animation" in the drop down list of objects under "Link to" select your object and leave all four check boxes checked.

Hope that helps.

Okay thanks this did work. Now how can you get the spotlight "source" to show on a render? What it lights and wher the light falls shows up but looking directly into the light renders nothing.  I know a point light will render but I want it to be shining in one direction.  Thoughts?

I'm not sure if lens flares work for a spotlight.

You can always add low intensity point lights with a lens flare at the point of origin of your spotlights.

Lens flare works for a spot light or you could make the light volumetric with a small amount of intensity (0.1-0.2 volumetric intensity for a power 100 spot light).

I do the flashlight thing.  I create a hollow cone or cylinder composed of a mirrored material.  I add a point light at low intensity, and a spot light with the right power and width.

If you get them all sorted out and set in the right location within the cone or cylinder the light shows only in one direction.  The cylinder is better for a more confined beam.  

Included is a sample from an idea I used in one of the underwater scenes if did previously.

I should have added that the longer the cone or cylinder and the farther back you place the lighting in either of those types of objects, the tighter the beam and less seen when you rotate toward or away from the source.

What type of rendering times does this add? and did you use some fog so the light beams would be defined? it looks really good but am afraid if I have 8 of these the render times are going through the roof.....

Yes the more lights you use, rendering can be a problem especially for animation, and as indicated by Mark I use Volumetric lighting.  I intentionally overdid the hazed light a bit for the example.  I have also used a slight fog or haze confined to the altitude the object is located in to make the light even more dramatic, but this will add to the rendering.  The more you confine the width and strength of the beam the less light to render.

 

Since I have two computers I do not worry about the rendering time, but note that many do diminish some of the special and anti-alias settings before rendering.  Sorry I cannot think of which thread this discussion took place, perhaps someone else will remember.

Yes I am using this to animate the bottom portion of a spaceship to give it some "life".  I wish I had a quad cpu super duper PC but I don't.

I here ya! 

I am still using Pentium D's with 2 gigs of ram so I have to be frugel as well.  I do not attempt the Hollywood Version or my computer just quits. A dual Qad with 16 gigs and two 8800 SLI's would be nice, but the piggy bank isn't full. 

Oh what a pain to be creative and handcuffed as well!
