Maya for 3D Printing - Rapid Prototyping

In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

I am a long way from finishing this truck model but i do have a quick question... how do i make the spotlight for the headlights not pointy at the beginning? i need the light to be as wide as the lens of the light (geometry). any suggestions?

Are you using a point light? change to spotlight and adjust the cone angle and play with the settings

I havent played with lights for a while. Open this file and do a render, is this what you wanted?

Decided to open maya and have a play to see if I can help you. Found this and think it is what your looking for. Want to go to your spotlight attributes and enable decay regions. These don't control decay so much as split your light into three sections and control where each second exists in relation to distance from the start. By default they didn't line up, but change the values so they all meet each other and then adjust your start point to get the correct size of the start of your cone (will need to render to see), then back your light up a bit to compensate for the new distance away from your lamps it starts at.

Hope that makes sense and helps. Ckyuk

ok this is what i'm talking about, only now you've got the cone angle too big coming out of the lens geometry. think about the way a real headlight looks. more of a narrow beam of light. although you are on the right track. and thanks for your help.

i tried the settings you have for my decay regions but it won't let me change them to what you have. each time i type in a value and press enter, it goes to some random number.

The only reason I can think of that would cause it to change the number your putting in is if your trying to enter a number in one of the regions that is higher than the first number in the next region. Work backwards setting region 3 first then 2 and finally 1.

--Edit-- Also you don't want to just copy my numbers as they will be completely wrong for the lamp in your scene, just have a play with your own numbers.

peterbilt 359 2nd post

Still not finished hence the post in WIP... thought i might get some feedback though. I would eventually like to get some environment reflections in the chrome to make it more realistic. I also plan to have this thing lit up like a christmas tree in its final renders...

Looks good so far. You might get more feedback if you posted some wires and stuff.

Put some tread on the tyres if you are going for a realistic look...just a bump should do it. Lit up like a Xmas tree? in what way mate? you mean the usual truck mini lights? Also I would think about (depending on previous question) whether this will be a day or night shot for the final render. Did you end up getting the headlight issue sorted out?
