I have almost finished my runaway mine cart animation and have started to add some lights.
How do I make light come from inside of the gas lamp I have made in the pic below? :P

Thanks guys :-*

just position a local light as a child of the lamp in scene mode, and voila! you might want to play around with the glass bit, maybe make it more see-through, and perhaps give it some emissive, so that it looks like it's glowing as a result of having the light in there - the light probably won't affect the lamp itself properly, if it's inside, which is why i think emissiveness on the glass might be a good idea.
hopefully not too complex ;)

Also, if you plan on using shadows, you'll need to make the glass of the lamp a different object, then add it in the scene and make it a child of the rest of the lamp as well. You want to do this because you don't want the lamp glass/shade to cast shadows. Otherwise the light wont actually affect anything.
-
Thanks guys. I would prefer the lamp to cast shadows in the tunnels and over the track and cart as it goes past, I'll give it a go.
I will need about 50 single lights aroung the track so it could take some time.
Not sure if you can see it in the pic, but when I render that lamp I get a strange stripped effect only on the top red and blue parts.
Any ideas why?
Thanks for the (again)

If you are using volume shadows, you can get stripey things like that. Use raytraced shadows instead, volume shadows don't yet work properly.
Regarding the shadow problem, you can place a light within the gas lamp, as thecolclough suggested, and enable shadows on the light, but disallow the gas lamp object element from casting shadows itself. Double clicking the gas lamp in scene mode opens its properties box, and you can make sure the "casts" check box is not selected. That way the light will get out of the lamp, but it will get out evenly in all directions. Hihosilver's method would give a more accurate result, with only the glass not casting shadows, but the base, top and side struts of the lamp will cast large shadows around the place. Softening the shadows will help, but you would be well on the way to very long render times.

Feel a bit of an idiot to be honest. :P :P
Have discovered why I was getting that stripey effect:
I had managed to duplicate a couple of the parts on top of each other and that was giving that strange effect. 8)
Thanks for the help

That looks cool! How long did that take to make? Plus I hope the runaway mine cart animation goes well

That little lamp took under an hour to model as it's not very complicated.
The runaway mine cart is fully animated now just adding the last few tunnels and then I'll add the lamps and lighting.

cool 8) i'm really looking forward to seeing this finished, it sounds like it's going to be quite a fun video to watch (i like tunnels and underground places :D ). are you going to put it on youtube?
- colclough

Not sure about youtube yet. :-\
Should be able to finish it now though, just got an extra 2gig of mem, graphics card and a core duo2 chip (that was the best my motherboard would support). ;D
Sweet. 8)

Cool man. I am eager to see the animation (Looks really good). The lamp does look good, not sure about the textures though
-
I agree, I used the red & blue to make modeling a little easier.
I plan to give the lamp a kind of rusty old look.
-
Yeah that would look impressive! An old rusty lamp on an old rusty cart. That would be pritty impressive for the lighting effects, what else is in your animation?
-
Here's a quick screen shot, I have not added any of the props yet.

looking very cool! can't wait to see the version with lighting ;D

Thanks TC
Just checked out your movies on youtube. :o
Very impressive, don't think my movie is on par with yours just yet. :)
-
That does look cool, I like the rusty texture on your cart. Hope all goes well
-
you're welcome, falloffalot! and thanks for the kind words about my videos, i'm really glad you liked them ;D
- colclough

This looks like it will be a good animation,Like thecloclough I can't wait to see it with the lighting :) Oh and one more thing,Why does the cart look like it has blood stains on it ???(DUN DUN DUNNNNN) ???
-
Ha ha ha :D
Like the "DUN DUN DUNNNNN" at the end :o
-
I love your oil lamp, very realistic.
Your screenshot has made me all curious to see the finished movie. Move over Indiana J ;D
-
I saw your cart picture, unless it's the camera angle, the textures looked really blurred and so can't give the intensity needed for a dangerous ambiance as denoted by the "DANGER" sign.
Hope my crits aren't too harsh.
-
i agree that in the still, with 'broad daylight', the textures do look a bit low-res and unconvincing. but... in the finished video, with the camera rushing around all over the place, and much darker, patchier lighting going on, the effect should be a lot less noticeable. you can usually get away with much less-detailed models in a fast-moving action scene than you can in a close-up, high-res still.
maybe you might want to upgrade a couple of the lowest-res textures, but don't worry about it too much, especially for the bits the camera won't have time to scrutinize :)

Thanks guys.
Any feedback is good feedback in my eyes.
To be honest I'm having a bit of trouble with the lighting and shadows again :P
I just can't seem to get the hang of it, but I'll keep trying until I do ;)
I have quite a few more props to add to make it a bit more "DUN DUN DUNNNNN" :D
Hopefully it should be ready for viewing soon, just don't expect too much as this will be my first ever animation.
PS. If anyone has got a sound effect of a running train that would be suitable, could you please mail it?
