Got a question about creating planetary rings - the Disc object may be able to do it, so it seems, but I've yet to figure out how to position it or a planet so that the ring is at the planet's equator. Or maybe that's not possible just yet? No biggie, just curious.
you just translate it down using the cords. here I set a ring up for you.

I asked the same question some time ago...here is the link...

I think he is dealing with putting rocks around a planet to create a more detailed ring, I know someone did it one of the alpha team and it looked nice in somewhere around these fourms.

I posted an example here (http://forums.planetside.co.uk/index.php?topic=467.msg4025#msg4025)
It's more complex than just the disc idea, but I've been able to render over 1,000,000 rocks in a very minimal time.
Very interesting. Somehow I missed that.
ya I missed that too.....very nice Sardine....
I remember that, didn't see the zip file though, playing with it now.

Still looks a bit tricky, but I'll play with it & see what I get. Thanks, Will & everyone!!
When rendering the full population in that pic I have a through camera mask set up to limit the population to just the visible aria. Also if you edit the image mask and color the non-visible arias black that will also optimize things a little as well.
do you think if I changed the image to add a bit more noise around the disk it would create a more realistic disk population?
Regards,
Will
I found that a fade in the image mask works great -the rocks will slowly get thinner as they approach the black arias of the mask. The image I used in the example is very basic, I've since added several gray>>black rings toward the center so the rocks are further apart and don't form such a hard line in my scene.
I was doing my own experiments with rings about a week ago, using Fake Stones but had some problems with the space between the stones being solid. Ultimately I canned the project so that I could focus on more important parts of Terracell, but I might like to use this in Terracell at some point, if I may?
Here what I've come up with so far.

Will
Nice job.
Thanks, I tryied to get a thicker band but terragen crashed when render so for now this is all you guys get.
Regards,
Will
Nice rings...

Hey go for it! I was actually thinking of offering to do this part for you when you mentioned the possibility of adding rings to Terracell. However, I really don't have the time (haven't done a single render in almost a week :'()
Please use what I've posted, it's for everybody to use/learn.

Here is my go at Planet Rings. There are two Populations and two Ring masks. I am however having trouble getting the image of Saturn to map correctly, it is currently through the camera.
Enjoy

Here is the files I used to create the above scene.
It includes two ring mask images, the projection image of Saturn, the .tgd file and a .tgo file for the rock. Thanks Sardine for the insight into this technique, I hope others will put their ideas into making this better.

Nice efforts and thanks for sharing.
Wow...That's a wierd but nice picture. I especially like those layers in the rock on the planet that the camera is on.
Nice picture only thing I would say is give the clouds a little bit more depth, right now they look almost completely flat.

These are rings made out of discs, there are nine discs with a gap. The problem I ran into with the discs is that they are jagged at the edge, on the far left of the rings. It might not be too noticeable at this size.

You will want to use Spherical Projection to wrap onto a planet. You will need to specify the position of the texture as the center point of the planet and the size to be equivalent to the planet size as well, I believe.

Thanks Oshyan I will givwe that a try, I hadn't tried scaling the image size. :)
Wonderful render, Trail!
Thanks, old_blaggard!
great use of disks, I like the tiny moon too :)

Where you able to get the disks to be partly transparent? I know that is why I like the population route, because I couldn't get the disks to be see through.
doesn't look like it, but at that distence from the ring a disk looks fine, a population is only nessary when you are close enough.
Regards,
Will
Your right on the distance part Just thought I would through out the question. :)
Sonshine777, I didn't do anything with transparency or opacity. I did try though! There may be ways to control this in the Node settings for those up to speed unlike me :) I did put a gap in the discs to give an illusion of transparency.
I posted my tgd file awhile back, when I needed cloud help, here's the post, if you want to take a look at the discs:

My solution was to make a 3-D ring object in Maya

It will look better when transparency works.
