Hello, this is my first post after looking at all the info on here for quite a while.
I’ve used blender to make some space craft but I have problems when I try to add lights to them.
I first tried puting a light on the side of the ship but discoveded you can see where the light comes from only where it is reflected. Secondly I made a coloured, transparent sphere and put the light inside, however the light never gets out of the sphere. Finaly I tried using the emitance value of the sphere but the light it emits doesn’t seem to reflect of anything so I don’t get the desired look of the light on the side of the ship.
Is there a fix for this? So I can see the light bulb and also have it reflect of the ship.
Also if I want to animate the ship I can seem to move lights along with it, is there a fix for this too?
I had a problem exactly like this one to solve several months ago. It is solvable, I can tell you. How? I can’t tells you exactly because I would have to rediscover the solution. But it have to do with allowing the globe to not cast shadows if I remember. This allows the light to pass through. And the globe needs to have some ambience and/or emitance. Sorry I’m not of much more help but I hope I gave you usefull directions.
it’s the source of light inside going thourgh the hemisphere
whic is colorless and transparent
and this does not affect the radiosity beause is normal white light ?
i’v been looking for something like this i think for a long time
and may be you have a solution here to get some radiosity around
with light source inside
now what about color
i mean if you add a colored lens instead - is it going to work ok?
in field many times you have a colored lens with an ordinary lamp inside
the color being provided by the lens not the lamp
because you could set a color on the lamp itself i guess
but not looking as real in the render
Here’s a blend and pic that might be helpful for the original poster (radm4). I didn’t use any transparency. Instead, I made the bulbs unaffected by raytracing or buffered shadows. I’ve used point lamps with raytraced shadows. The pic was rendered with soft shadows, but I turned them off in the blend because they slow things down.
I also parented (CTRL-P) the lamps to the block they are on so they will move at the same time.
