Car headlights

[jakerupert]

I am trying to build some headlights for a car.

 

But I cant seem to get it right.

I get some strange kind of "offset dublication" and a very sharp edge at the end of the cone.

(see pictures)

multipass 5 passes

 

Any ideas, how I can get rid of that?

 

Any good example of a headlight and backlight somebody could post?

 

And also, whatfor is the lightwindow that opens up, when clicking a light object in the PWS?

It only seems to stay all black for me.

Hello try using no pass and 9 passes that will clean it up

i used a rim light with volumetric on for the test

here are shots and setting

the blurred one is a 4 pass

I think it is only for previewing lens flares. Those are the only things that seem to show up in the light window.

Must be still something else...

it allmost looks like thats where the ground intersecs the light from the cameras point of view , does it do that as the same spot if u move the camera ???

after some more fumbling around, I guess I managed to achieve some convincing carlights?

 

Critics welcome-

[jakerupert]

Seems I have been happy too early.

 

While copying(dublicating) the backlights(bones) for some directionallights(bones) with control click, afterwards I tried to switch just this conesize,

but couldn`t find its property any more, simply vanished.

Then restarted AM , property there again, switched it from 60 to 80 and my rendering went ballony.

Seems to have switched all the conesizes at the same time, though its not telling it..

 

and the rendertimes went through the roof.

 

So is this some kind of known sturdiness in this field or am I simply doing things wrong in the

handling?

Am I not meant to be able to alter the conesizes after dublicating alightbone with control/click?

[John Bigboote]

I'm not familiar with 'copy click' that you mention.

[jakerupert]

sorry , I meant control /click

[jakerupert]

Seems everybody is avoiding this topic,

leads me to the conclusion, that it is very difficult to handle.

 

I have never seen a convincing example of some carlights in this forum also.

Maybe because all the carproducers around here are just doing stills and no animation.

 

Maybe it was the control/click copying of the lightbones inside the model that caused the trouble?

I will return and build the different lights externally from the model and then draging it on top of the

model one by one as a workaround.

 

Lets see , if that makes a difference.

 

(If its a known "critter", please tell me, so I could fill in a report.)

[jakerupert]

Maybe there is something broken with model internal lights in 15f?

 

Whenever I save some lights with my model and reopen it later after restarting AM all the light(bones ) are just gone.

 

Can somebody test this also to doublecheck if I am not the only one, please.

[jakerupert]

in further investigating this phenomenon I found, that on my newer computer with Win Vista AM 15e CD-version

I can save models with lights allright.

On my XP with 15f web I cant, also I tried with no succsses 15e Web.

 

After restart of AM the lightbones simply are gone.

 

(Any idea anybody, what this might cause?)

 

So I am asking if anybody else can reproduce this?

 

Come on, all your suportive ghosts on this forum, it`s not that hard to put a light into one of your models and

see, if it gets saved in 15e/f Web, is it?

 

....else I will have to continue talking to myself (sigh).

web v15f XP unlimited added a light to model,set volumetrics to on.Saved model close AM restart AM,only change is the volumetrics is turned off but the light is saved with the model seems to be working fine on my pc

[Paul Forwood]

There does seem to be a glitch with volumetric lights in A:M15.0f on XP machines but it might just be a refresh issue. (See image).

[robcat2075]

i noticed in V13 that a light duplicated in a model would lose a property so i created the light as a new object and dragged that into the model. That seemed to work.

 

I can't get the light cone to appear to fade to 0 at the end of its beam. it always seems to have a detectable stop to it. But it's not bad.

 

Volumetric lights are a post effect , I think, not a rigorous physical simulation of light physics. lights that overlap can have odd appearances.

because that means "I am at the end with my latin" somehow now, as they say here.

I reinstalled 15 f with no avail... any more ideas, what I can try to encircle the problem?

 

Paul, Robcad, have you been able to add lights to a model without them vanishing later?

[robcat2075]

I was able to reopen my project and the lights were still there. Were you able to load mine in V15 and the lights were still there?

 

It's odd that a light would disappear and not any other bone.

 

you might examine your saved file and see if the lights were not saved or if they are there and disappear on re-opening.

But how can they disappear then on reopening?

 

I post the testmodelfile.

 

Can you find something strange there?

Your model does not have a light in it.

 

I added a light (it only shows as a "bone"), changed it to klieg, turned volumetrics on in light properties - closed A:M - brought it back in - and it was still there - 15e, pc

[jakerupert]

-Hm , maybe it IS working when you actually create the light in the model and NOT working, when you drag

an externally created light onto the model?

 

I will continue my tests next week.

[yoda64]

The problem in your case is , that the lights in your model are not embedded , they are linked .

Under this conditions the reload for the linked lights fails .

 

As a workaround for now , embed all lights into the model .

[jakerupert]

>As a workaround for now , embed all lights into the model .

 

 

 

As a positive sideeffect, I did the lights external as actionobjects in four different actions

1. drivelight, (front and backlight)

2.brakelight

3.right directionallight

4.left directionallight

 

here`s a testrender no multipass...
