View Full Version : Saab Cabriolet

This was done in Lightwave v8.5 with a bit of post work in Paint Shop Pro.
Image was done using two model available to Premiere Members. These were set into a large box with a very dark grey surface. There was a second, smaller, box with a city image mapped to the inside of it and made invisible to the camera; this provided an environment for the car to reflect. The scene was lit with a single spotlight and background radiosity set to 4x12 bounces.

pretty sweet render Rigel . . . double box concept is a nifty idea, question . . why did you keep the radiosity at 4x12 base?

Very nice. Got to love the ability to turn the world invisible in Lightwave!

Thanks everyone, I'm glad you like it.
@gpdesigner; That was the default setting and I figured that would be as high as I could go and keep the render times reasonable.
Oddly, when I originally did the render with a Medium Classic AA and the 4x12 radiosity, it took 3 hours and 40 minutes to render. I was having some problems with jaggies, so I played with the AA settings and decided that a PLD 9-Pass Classic would do the job (and it did). But that only took 1 hour and 58 minutes to render. Not what I expected. I expected 9 passes to take longer than the Medium setting, which does 5 I believe.
At any rate, it came out with the edges of the sign looking non-jaggy, which is what I was aiming for.
Also, the quality of the render lies squarely on the shoulders of the modeller; without that excellent car mesh, the render would not have been so nice. I didn't even have to texture the car *whew*.

I think the PLD settings are not as pumped as the classics, medium in the classics is 9 passes as well . . . I always use PLD except today when I tried to do a DOF render . . .
good image tho . . .

Glad to see this one worked out for you in the end Rigel.

Looks interesting :). Somehow it's looking little blurry to me like it's JPG compresion or resized too much ?

I think it is too soft as well, and I also don't think the environment reflection works in a totally black(pretty much) visible environment. I'd personally like to the lighting a little brighter, and more contrasty (just a touch). I'd also like to see the classic white light box reflections, and this to me is a tried and tested setting for studio rendering. Doing things differently isn't a bad thing, but I don't personally think it works very well in this instance.

@Lewis; yeah, it's a bit soft. For the life of me I could not get rid of the jaggies on the edges of the sign or the car, until I checked Soft Filter under the camera properites. I was rendering on Extreme High and still getting jaggies. Totally stumped me as I've never had such a problem before.
@Craig; I understand what you mean about the reflection. I tried it just with the environment, but the car looked flat. Question: what do mean by white light box reflections? Would that entail putting in some window size/shaped polygons and cranking up their luminosity? If so, maybe I'll do another set up (front view next time maybe) and try your suggestions.

Any size flat polygons you like. Take a look at Lewis's renders for good examples.

Okay, I'll try that and see what happens.
