Well, time has passed and I haven't gotten anywhere on my curls.. especially since I tried to export the pub as a swf and was really not happy with how the vectors looked. It's as if they were lacking certain coordinates making them slightly out of place and jagged.
I'm a perfectionist trying to get something to look pleasing as a web site homepage, and if I don't get this right, I won't be happy.
I managed to get one curl working.. kinda... and the more I try to battle with Opus, the more I get tired of it and want to just rack my brains, recreating it in Flash.
Have a look at the attached .zip/.imp for your viewing.
As you will see, the curls (link1 is the only one that works so far) appear as though they fill up the tubes (the effect I was looking for). They do tend to destroy themselves and muck up if you mouseover then mouseexit before the tube fills completely, and also doesn't show properly unless you wait 2 seconds before refilling.
You will also see the difference between exporting to exe and swf.
I'm sorry I have to say this, but I have to abandon opus for this project, since it cannot cater for my needs like it should. (or at least I can't make it cater for my needs)
I would like to say thank you again, Larry, for your help so far. It'll certainly come in handy for future projects.
If somehow, someone manages to make the curls work perfectly when exported to swf, then... then..... then I will eat my hat.
