Rendering Headlamp Doubt 2

[karthick_241187]

Hi guys,


I have one more doubt in rendering headlmp,
I m not getting the results like real time.
in lens onver the turn signal region, we have some steps.
so that turn signal area should look jiggled due the steps in the lens.
but in raytrace render its not that much jiggled.

u guys check out some headlamp pics and also the images i have attached

Thanks in advance for those who reply.

This is nothing but the rendering image of raytrace.

kindly check it out and help me

Thanks again

Hi Karthick,

I've had a look and I can't help you but maybe you can help me? Or anyone else?
How have you created your red metallic shader with the silver flecks? It looks like a real metallic paint, not just a flat colour.
I have been trying for a long time but cannot perfect it. Can you help me please?

Many thanks - Manish

Hi Manish,

Hope u r using showcase 2010.

Under Materials Tab u can find something as Car Paint.

In that u can find these kind of metallic paints.

I didnt created these paint materials

I'm not quite sure what your question is. I have a lot of experience with headlamp and rear lamps I can probably help you any questions that you may have. I have attached some samples of some of my work

Hi Worfsonofmogh,

I m very much happy to have u r comment.

I have seen u r rendering long time back.

U said u r in lamp field. U would have know about flutings or steps in outer lens.

so while seeing through that stepped lens, the bulb and the chamber ll look jigled.

I want to know how to create those kind of effect.

I also want u r help in rendering Rear lamp.

Thanks for u r reply.

Looking forward for u r reply.

Thanks

You might start by using a bump map and use a bulge texture set the U and V repeat to 1 and 12 to achive the flute look or an equal number ( 4X4 to achieve the pillow look adjust the refractive index to 2 or higher to get the refraction through the bump map texture

Hi Worfsonofmogh,

Thanks for u r comment.
The purpose of rendering lamp is check the styling appearance before we go for RPT.
So if i use bump maps, the results wont be precise.
I actualy tried in showcase by increasing the raytrace value above 5, only then i m able to acheive the desired result.
But the too much of raytrace or resulting in collage like reflections in other areas like extension and low beam \ high beam reflector.
Becoz of this too much reflections, we are not able to see the reflector step pattern.
Looking forward for u r reply.

In my experience, the only way to achieve what you are pursuing is to have actual 3D CAD data that is exact geometry that production tools willl be made from. You would need to build data that had the actual surface shape and definiton of the optics that you are trying to render. In my opinion you will not be able to simulate exactly what production will be. I have had these issues many times in my experience. You may also be asked to render an image that simulates what your lamp looks like when lit. Again you will never be able to convince the skeptics. you can get close but never exact. Here's a question when was the last time you needed sunglasses to view a "picture" of a sunset?
