Title: Lights
Post by: VBSmiles on September 15, 2008, 08:59:38 pm
I like the new global lighting intensity you added to the program, but was wondering why you didn't add them as a component of each light? It would seem more useful this way, ( but then I'm not up to par on the 3d stuff internally as much as I used to be, though understand that global lighting is different from the lights itself )

It was already possible to change the intensity of each light in the previous versions - the intensity is determined by the light color. For example black means no light, dark blue makes a dimmed light, light blue is a normal colored light and white is full intensity.

After I posted I thought about my post, and remembered how lights in a 3d environment internally work. My request was in ignorance.  :-\

I do have another thought stiring though. uh oh  :o

Too bad I don't presently have access to my computer. I'm now wondering if the materials Emissive would be brighter with less lighting.

uh oh indeed... :P ;D

yes, in theory the same emissive value would appear brighter, by comparison, if you lowered all the other lighting in the scene.  it wouldn't be brighter, but if you reduce the lighting enough, then it would look as if it was.

The following lighting controls are present in Anim8or now:

1. Each lights color - can be animated with a controller.  Has been there for a long time.
2. Global lighting intensity - brightens or dims all lights.  Useful when there are a lot of lights and the scene is too bright such as  simulating various global effects.  New to v0.97c.
3. Gloabl ambient intensity - scales ambient lighting factor.  Set to 0 for completely dark shadows.  New to v0.97c.
4. Individual light's intenisty.  Animatable with controller "intensity" for each light.  Not quite finished in time for v0.97c release - can't seem to fix a couple of bugs in it!  This will act like a dimmer for the light so you don't have to animate the color which is somewhat harder to manipulate than an overall dimmer control.  May be there for next prerelease if I can get to it.  (Don't hold your breath :))

There is no "dimmer" control for the emissive component however.  I haven't decided what's really useful here.  I'd rather work on animated materials in general than to spend time on this.

i was about to say "i don't think there should be - surely the whole point of emissive components is that your object has a constant glow-in-the-dark factor, which stays the same irrespective of what the lights are doing in the scene?" ... but then again, it could be very useful for things like making a control panel light up, or making a fire flicker, so yes, if you can make it work, that would be pretty cool.

I'd rather work on animated materials in general ...
animated materials?  excellent ;D

Cool deal Steven, and nice insight to whats coming :)
