I use Photoshop to make skins for cars in a driving game (Live for Speed). I’ve been trying to do some curved designs on the cars but the curve always comes out very jagged even with the AA box ticked. So, my question is, is there a way to draw curves without them being so jagged once the image has been saved as a jpeg? It has to be saved as a jpeg so that the game recognises it.

Cheers.

I don’t know if this will help you in your situation, but when I want things really smooth, I work with the image about 2X the final size it needs to be. Once I am ready to save, I resize the image to the final size.

This ‘resizing’ step tends to smooth all the lines and add some extra anti-aliasing. You could then even play with masks to selectivley sharpen some parts of the image while leaving the lines you need smooth untouched.

This is a practice I use too, but with one caveat. I save my image as a PNG which is lossless, and more importantly, flattened. This prevents any of the layer effects from altering–like drop shadows, bevels, etc. And yes, the curved lines do appear to be much smoother. I top it all off with a tiny bit of Unsharp Mask sharpening, usually in the pixel radius range of .3 or .4 at or just below 100%.

Try this. Blur the curve till the ragged edges disappear. Then to go to levels and bring the sliders together until the blur disappears. You should have a much smoother edge.
