Description Quite a few of you have asked me to write up a tutorial of how I created the asteroid-rings in Phenomenal View . Well, here you go

Also, which might be to your interest, I included the .vue-file in the download which is the final scene of the tutorial. Hit the download-button and rejoice

I hope you will enjoy this tutorial. If there are still questions left, feel free to ask me.

Comments and favs are, as usually, highly appreciated.

If you decide to use this tutorial for any of your scenes, crediting is highly appreciated. Also, it'd be great if you could link me to it so that I can view your work. Cheers!

hmmm, okay, try the following:

- uncheck "Dynamic Population"
- set the overall scaling to 1.000
- leave the overall density somewhere below 35%
- set the size-variation to 50 (+/- 20)
- hit the populate-button (in case the dialog for dynamic population pops up: don't let is use dynamic population)
- render the scene

That is probably the reason why I dislike dynamic population: just acting really weird sometimes :/
Please tell me if that helped

I did what you said to me but it wasn't better so I did the tuto again from the start and by not using the dynamic population I have a result and it doesn't lag

Here you can see my fast rendering: I wont use the planet so don't worry about that ^^

Now I'll see how to export only asteroids to add them into my photoshop scene

BLPH In reply to MA7R [2010-02-28 12:53:06 +0000 UTC]

That does look pretty sweet! Really well done

About the exporting; I'd do it the following way: think about where the light will come from in your PS-scene to adjust it in Vue (in order to not have 2 different lighting sources). Then, render the asteroids and save the bitmap as well as the alpha-mask. You could also use a different file format which supports alpha-information (PNG, TIF, for example) and tick the "Embed Alpha Information" option

A newb question, why can't I get my thing to populate everywhere? it always seems to have holes in the population or strange things like that. I can't get it to populate the entire ring completly. I've tried all sorts of settings and nothing I try will get it to populate evenly like in your images.

πŸ‘: 0 ⏩: 1

BLPH In reply to Superiorgamer [2010-02-20 10:53:44 +0000 UTC]

Well, this is kinda difficult to troubleshoot but I'll try.

Possible factors are:
- Variable Density enabled
- low density in general
- hidden objects placed inside your plane

Variable Density gives you a lot of control of your population, however, it is hard to actually use it right. That's why (if you haven't done so already) it's better to have it turned off/unchecked.
To fight low density, you just have to push up the slider. I know, this sounds rather obvious, but I just wanted to say it
Hidden objects might appear everywhere. Check, if necessary, whether you have objects in different (and maybe hidden) layers. Vue won't populate places where there are already objects set.

Hope I could help you. If not, feel free to tell me so

The only bad thing about it is that you can use the low poly rocks which doesn't look very good in my opinion. I have tried a bunch of different techniques using my asteroid technique but can't get any luck. Will try more of course Nice tut (goes in my resource folder )

BLPH In reply to aRchAng3lZz [2010-02-18 21:31:21 +0000 UTC]

Thanks, bud
Well, on the other hand, using high-poly rocks will enlarge your scene massively, causing the famous shitlag. And after all, we don't possess Photoshop to avoid using it for touch-ups

hehe, I tried that but in the end I messed up with the parts and when I tried to fix it, vue crashed

That's why I stick to the good ol' (yet incredibly slow) full render

Very nice, I've found my own ways too but some aspects are similar to this. it dosn't look all that great at first but really picks up in those final renders

πŸ‘: 0 ⏩: 1

BLPH In reply to Chromattix [2010-02-17 13:53:55 +0000 UTC]

It does, yeah. The fact that vue wouldn't populate "inside of objects" annoyed the heck out of me, seeing that you cannot properly populate two overlapping terrains this way. As a result, there was a natural question popping up in my head: why is it doing that?
So I kept investigating and found some usage of that "flaw"
Funny though, that some really cool effects are initially created by accident

Just got my hands on Vue and will try this out for sure - only issue I have with the result is the lack of decline in size the further away the ring gets. In that green picture for instance, there's a big boulder on the far side of the planet that in reality would be almost 1/4th of the entire planets size. I guess you could scale everything up, but my guess is that it'd take forever to render if you did. :/

Still a nice tut though

πŸ‘: 0 ⏩: 1

BLPH In reply to tadp0l3 [2010-02-15 16:20:02 +0000 UTC]

Well, rendering this kind of scenes is not the main issue, it's more the problem with Vue's response time in relation to the amount of instances. You are right in that matter that a further scaling up slows down the whole process.

After all, you can still hit the populate-button another time, thus making the bigger asteroids appear in different places. Another thing possible would be to decrease the size variation to a value like 30, 20, or even 10. This way, the rocks get more even in size and, depending on the overall scaling, have a better relation to the planet

Of course, another method to avoid having the "big boys" directly in front of your camera would be to simply move the camera. But I guess I don't say anything new here

tadp0l3 In reply to BLPH [2010-02-15 18:09:33 +0000 UTC]

Well, it's not exactly the asteroids in the foreground that bothers me, but the asteroids in the background, on the far side of the planet. Some of those asteroids are bigger than most moons would be. The ring lacks a bit in perspective :/

πŸ‘: 0 ⏩: 1

BLPH In reply to tadp0l3 [2010-02-15 18:33:30 +0000 UTC]

Ah, now I get your point about enlarging the size! Well, yes, in this matter, it does help with the perspective. However, the fact that it will heavily slow down your computer might be a little downside.

Yet, I'm still trying to gain a little more knowledge about the function editor, thus messing a little with the "variable scaling" function. I know that certain functions react on the distance to the camera, which should be usable for helping the perspective to better come out. But as I said, I haven't gotten that far yet...

tadp0l3 In reply to BLPH [2010-02-15 19:43:34 +0000 UTC]

Sounds interesting though, I'm currently rendering my first asteroids basically following your tutorial. The size in vastly increased, and I can't even move the camera around without getting huge lags and long freezes in vue. I think I got a decent enough angle and am currently rendering the scene.

I'd be very grateful if you noted me with the progress on variable scaling, it'd be super to get that working, and as a vue newbie I wouldn't even know where to start, heh.
