Title: I welcome you to a very cloudy planet
Post by: Will on January 10, 2007, 02:31:31 PM
Hey guys this is my first orbital shot. Ive been playing around with the cloud and the planet shader. I was also wondering if anyone had figured out a way to make a forest like looking area with the planet shader. anyway tell me what you think.

haha very nice. this is very much like my first one as well.

Well I havnt found a way to get trees with planet shader. theres not alot you can really do with that shader(trust me I've been messing with that thing nearly every day)

but of course there are things Im not sure that do things.

if theres a will theres a way. :D

What is impressive is how Terragen will also remember to render the atmosphere halo on the edge of the planet.   The blue looks a little dark - if the colour is lightened in the atmosphere settings would it change the colour of the halo?

yes ive been playing around with that, I think it has to do with the bluesky additve and the red decay.

TG2 is not rendering a halo as such, just that the atmosphere extends higher than clouds all over the planet surface.

I think most people would have tried a render from space (or high in the atmosphere) first. There are several reasons:
1. It looks impressive.
2. You could only dream of putting the camera above the clouds in the old Terragen.
3. It is easy.
4. You can see how your first play with the settings has influenced the entire planet.

I have not yet progressed to putting the camera near the ground, but the picture here (http://forums.planetside.co.uk/index.php?topic=430.0) has inspired me to do that next.

I agree dark fire I think playinf in space can be helpful to those who are new to terragen or (like me) node based programs in genral.

Also I was wondering how you could apply the crader shader to the planet shade effectivly, for example in the thread Fun with the crater shader you 3Dguy seemed to get some pretty cool resualts out of the crater shading and even things resembling tital waves. I'm now wondering wether you could use it to make a nice looking meteor impact, like the ones you always see on the science channel speicals about the end of the dinosuars.

You can create a meteor impact with the crater shader, but you might want to fiddle with a few colour settings and add some random rocks to make it look authentic.

I've seen a post somewhere where a very large crater messed up the planet, it produced a black hole in the planet. Seems very large craters have some issues.

Yea but can you connect the crater shader to the planet shader and have it work? I've tried playing around with it but I can never seem to find where the creater is :)

Not directly. As far as I know. You'll need to have a compute terrain between it. Default it's located at one of the corners (lower left) of the default heightfield square you see when you start a new scene.

alright Ill try it thanks man.

Post by: Will on January 12, 2007, 04:53:02 PM
well it does work but I can't seem to be able to change the position of the crator, do you think I need to use a transform for that?
Title: Re: I welcome you to a very cloudy planet
Post by: 3DGuy on January 12, 2007, 05:01:21 PM
The crater shader has 3 entries which give the x,y,z positions. It's the 1st line which says 'center'. Just move it by using entering values in the x and z (1st and 3rd box) boxes.

Post by: Will on January 12, 2007, 05:07:08 PM
I tryed that and it didn't work so I tryed the transform and only the scale worked, Im still trying to figure it out. Anyway Im getting the black hole thing your were talking about and Im seeing if it has to do with the depth of the crator. All keep you guys posted on things and thanks for the help :)

Doesn't work? The script I made (http://www.theglasseye.nl/terragen/) uses the x and z coordinates to move around the craters.

hmm how would you set up the nodes for this? I currently have the crater shader -> transform -> compute terran -> planet 1 I don't know all tha tmuch about nodes so this might just be more a problum with my in experence. Cool script by the way.
Title: Re: I welcome you to a very cloudy planet
Post by: 3DGuy on January 12, 2007, 05:25:09 PM
Much the same as you've stated. I would leave the base colours node in there so you can control the colour of your planet. Currently rendering a scene so my rig is a bit to busy to make you a screenshot at the moment.
Title: Re: I welcome you to a very cloudy planet
Post by: Will on January 12, 2007, 05:33:27 PM
yes I forgot to put that compute terrain is connect to the planet shader to give color, Ive added a rock to take the place of an asteroyed and it seems that once I put it a cordnate to move it it disapears, any idea what going on this is my first real try at nodes based editing so Im afraid im kind of flying blind in all this.
Title: Re: I welcome you to a very cloudy planet
Post by: 3DGuy on January 12, 2007, 05:40:10 PM
You're probably moving it out of view ;) Just remember that the second entry (y value) dictates the height. Move it a few meters at first so you know where it goes. You could also copy the values of your camera (except the y value) to put it directly below the camera position and finetune it from there. Not quite sure if you need to enter a Y value if your terrain has mountains though. Haven't quite experimented with that.

yea I tryed that but it just seems to dissapear after moving the object more then .7 in any direction. Its weird. Have you ever had the problum of not being able to mvoe somthing?

I just remembered a bug report on the rock object and found the thread again:
http://forums.planetside.co.uk/index.php?topic=354.0

Seems there's something wrong with the builtin rock object. So that may be the problem.

hmm that seems like the thing, Thanks 3DGuy  ;D Imm I could import a rock from VUE6 that would work I guess is the displacment working at the moment for imported objects?

Well it works, but there's some issues with that as well. See this thread:

I'm starting to think I spend too much time on the forums knowing all these threads exist :D

heh well then you could be consitered a honorary moderator then  ;) Anyway Im still working on this and ill keep this you guys updated on the projet but for now I must study for THE MIDTERMS! dododo who knows 8 hours away from terragen might acualy do me some good (yea, right :P). But one last thing does the planet shaders oceans work on a gradient? becuase they have peudo transarity getting greener near land.

To be honest, I have no idea. Seems they're blending the colours, but only the programmers can really answer that one.
