Trying to learn Carrara 3 - Polyloop

Rowan · 15th July 2005, 17:54

I've finally got my Carrara 3, and this is one of my first attempts at using it. The model was made in Amapi Pro 7.51 using Polys, then exported into Carrara for rendering. My only problem with it is the jagged join between the top part ond the bottom part (see the close-up of the back) I'm going to have a look at it and see what I can do. If anyone can suggest why it's doing that, please say.

Wireframe of the back?

At first glance, I would say that you didn't combine the points into one mesh with one polymesh. Also, since my guess is that they are two different objects, I also believe that they had different smoothing setting on them (rather it's the type of smoothing from Amapi, the level of details, or other parameter).

A wireframe picture is good, but so is the .car file as that would also us to really dig into the problem and find the reason.

Found the problem: It was two seperate objects. The bottom was supposed to be made from the outline of the top, but somehow it wasn't. Deleted the bottom and remodelled it with the outline of the top. Also added runners as some method for it to land. Quite pleased with the outcome really. Shows what even a person new to Carrara can do. By the way, credit goes to Dooki and Andrew for the tutorial on making the fan blades ;)

Hi. More questions, this time related to how-tos. Couldnt find a tutorial on this one... How can I make objects become light sources in Carrara 3? I need the three objects inside the hood to light up. The picture is from a test render in Amapi, but it shows the objects clearly enough.

You would have to use an Anything Glows object.
How the lighting works really depends on the Anything Glows settings...
The document is on page 105 of the Assemble pdf document (Help->Assemble inside C3)...
It explains the different parameters.

Um. No he wouldn't have too. For one CS3 has GI. And what type of glowing are you after? As in light sources? Or merely the appearance of being light sources. There are a few methods you could use.

1. Place the color/texture that you want your objects to glow into the glow channel of the objects shader. Then create a bulb that emits a similar colored light near the object to simulate the effect of the light emiting (cheap method but fast at rendering)

2. Repeat the beginning steps of step 1. but do not create a bulb, but instead render with GI. Keep in mind these tips: http://www.vizualds.com/article/various-gi-tips

When using GI.

3. OR you could use an anything glows object. Though I've found that they actually tend to render slower then GI would. Because an anything glows object simulates the effect of GI by duplicating as many lights as necessary to get the effect so you can end up with well over a 100 lights that the raytracer would have to calculate. Which would lead to high render times.

Goodluck.
