BlissC Posted December 5, 2008 Share Posted December 5, 2008 Hi guys, I'm fairly new to PDN. I've been using it a couple of months or so, and I've just discovered plugins and all the tutorials and stuff here and realised I can do more than just touching up photos (which was what I mainly used Paint Shop Pro for, which I used until my laptop died on me, then went looking for alternatives when I got my new one, and of course found PDN... ) Anyways, having made some exploding planets and metalic text, a few nice abstract backgrounds, and a 3D logo, following various tutorials, at the moment I'm working on re-working my forum banner (my current one's very badly pixelated in places and badly anti-aliased, and doesn't look professional at all). As part of the banner, one of the things I'm trying to do is to do a glass sphere, and I've checked out the various glass button/sphere/orb/ball tutorials, and searched the forums here, but can't find anything similar to what I'm trying to achieve exactly. Where I'm coming unstuck is trying to get a design around the outside of the sphere. Unlike the "kiosk orbs" tutorial, I'm not wanting to put something inside the sphere, but on it's surface. I’ve got two problems at the moment. While I can use Shape3D on my image to create the sphere, which I'm using a light coloured gradient background for, as obviously the glass would be transparent/translucent, I need the design around the surface of the sphere to be visible all the way around (i.e. how I'm imagining it in my head, you'd be able to see the reverse of the design through the sphere on the other side. Getting the design on the front of the sphere with Shape3D isn't a problem, but I can't figure out how I can get it showing through on the other side. My second problem’s that I originally started off following the glassy marbles tutorial, but unlike in the tutorial I’m using a gradient background rather than ‘clouds’ for the ball because I want it to be more transparent. To get a transparent/translucent effect though I figured I needed to reduce the opacity on the gradient so that when I finally figure out how to get the design on the surface of the ball on the other side, it’ll show through. I’ve currently got 2 layers – the background layer with the gradient, and a second layer with the design I want around the outside of the ball. With the two layers separate though, of course S3D turns the background layer into a nice sphere, but the pattern on the sphere’s just still flat right across the middle. Of course if I merge the two layers, the opacity of the design drops as well, which isn’t what I want – the pattern needs to be solid. The nearest thing I can find to show the kind of effect I’m trying to achieve is this, only the pattern I’m wanting to use is no-where near as complex - I'm wanting to put a design around the circumference of the sphere. I know I’m missing something here, and I suspect I’m probably missing some vital layers to achieve what I’m trying to achieve, but I can’t figure out what. I'm guessing that I probably need another layer for the design showing through from the back of the sphere, but I'm presuming I need to use something else other than S3D to get the right sort of curve on the back surface. I'm totally stumped on the opacity issue though, and can't work out how to get that to work. Could anyone give me any pointers please?
