Newbie Question - Polyloop

Snerp · 14th March 2006, 07:54

I've created a simple logo that has oval shapes using Carrara3. The problem I'm having is when I render the image at the best setting using HybridRayTracer, the ovals come out slightly jagged and not smooth. There is probably something simple that I'm not doing...any suggestions will be a great help.

What smooth value do you have for render (click Edit->smooth object...)

Snerp · 15th March 2006, 04:08

Sorry, my mistake, I'm using Carrara 2 and there isn't a smooth object option under edit...any other ideas?

If you created them in the spline modeler, then increase the "Surface Fidelity" under the "Geometry" tab to 400 and see how it looks.

When I created the oval shape, I just used a preset cylinder shape and transformed it to a thin oval. I've included a jpeg of the logo so you can see what I'm talking about. You will also see that the reflection on the chromed oval is banding as well.

If you want to you can upload your .car file and one us can look at it.

Ok here is the working file. Thanks for being so attentive to my problem, I really appreciate it.

you did'nt convert the primitive to a vertex model did you? I had good edges with the primitive until I converted to a vertex model and then the same flats showed up. i could'nt open your file(unknown type error)

When I tried opening your file I get this funny error message

Trying zipping the file first and then uploading it. Only if you still need help.

Here is a zipped file, hopefully this will work. It may be that I'm working from a Mac version of Carrara.

Snerp · 17th March 2006, 03:48

I ceated a new file and used the primitive cylinder and did a test render and it is smooth. I then took that same cyliner and scaled it down into a near flat face oval and did another test render and the edges came out ragged again...very odd. I guess you can't manipulate primitives and expect smooth edges.

Snerp you logo .zip is faulty!

Snerp · 17th March 2006, 16:47

I give up, thanks eveybody for your help. I think I'll stick to Illustrator.

Typically for any object, you either model in the resolution for smoothness OR you can subD the model. You can also turn on smoothing (a render effect) which may be enough in itself.

Carrara's learning curve is not that hard providing you're willing to at least peruse the PDF manual and familarize yourself with 3D concepts.

Going from illustrator to 3D is a big leap - don't let yourself get frustrated. At least you picked the RIGHT package to start with - trust me!
