NEBULA Tutorial Released

****************** EDIT 19 JAN 2005 *****************
Tutorial now available from www.cogfilms.com


Hi Cog here,

Whilst experimenting with the TIME IPO to slow down, stop, or reverse particles I discovered a neat way of simulating Nebulas.

Its 3D capability shows best with a fly through.

********************** EDIT ***************************
Here’s another star cluster nebula.

Here’s a fly-around to show the 3D texture and some proto-stars. (I’ve reduced the compression on this example because of the artifacting introduced in the previous example. Because this is a smaller concept it needs to be viewed in a dark room i.e., low ambient light.)

LAST CONCEPT BEFORE TUTORIAL

I’ve added a distant nebula (a simple cloud texture stretched onto a tube) and created a nice flythrough.

Take me to stella-cartography…

Tutorial soon.

Very nice, I like it. Any chance you can tell us how you did it?

Also, I like my nebulae to have portions with lots of texture and detail. Is this possible with your technique? Oh, and, how are the render times?

You might also consider sprinkling some bright young stars in there.

Hi stratacator,

I’ve just updated this post with a further example. You will see that proto-stars have been added. I have found that the textures for my needs should be quite subtle. However, I suspect that the possible variations are enormous.

Render times are reasonable as I only use 2 particle systems with low (Tot)al counts. I’ve also post processed a glow, via sequence editor, which also speeds the process.

I am creating a quick tutorial at the moment.

Cog

Please may I have a look at the .blend?

That is a beautiful nebula: one of the most realistic that I have seen made in a 3d program! I too would not mind a look at the .blend file, or at least a better explanation of how you made it (probably included in your tutorial). Great work!

Hi Jedi and Ryan,

I’m working on a tutorial at the moment, which I will post here and on my website. It’s usually not my policy to offer my .blend files because they often contain info or extracts from my film Cog. However, as you’ve asked I give below a link to a blend file of the second example.

Enjoy.

Cog

WOW! Very nice Nebulae! … i agree with ryan… definitly VERY realistic…

nicely done

Thanks! :smiley: Any chance of turning this into a cloud effect for things to fly through?

Thank you for bending your usual procedures and letting us look at the .blend file. I have never really gotten nebulas to look good, and maybe now I can figure out how! Thanks again.

Umm! Something like this?

Perhaps a fly through? Hang on…

Enjoy.

Cog

Can anybody under linux view these? Both Firefox and Konqueror choke on them here. Is there a plain link to the videos somewhere?

GreyBeard

IE & Firefox on Win XP work fine for me, but my link might be choked at the moment.

Here are direct links to try as well:-

  1. Nebula concept (fly through)

  2. Nebula concept (fly around with proto-stars)

  3. Nebula concept (fly around with distant nebula)

  4. Cloud concept

Cog

Thank you for the direct links :smiley:

GreyBeard

Wow, those do look nice…
Waiting for the tutorial!
I’ve never seen a way to get clouds look so good in blender like those…
Can’t wait to learn how to use it!

Looks really nice! Really looking forward to the tutorial … :smiley:

Hey cog.

Its been 4 months now. How about posting a tutorial so we ALL can take advantage of the knowledge of how you did this.

I would like to see both of cog’s up comming tuts

Hi all

A Happy New Year. I am still here although I have been incredibly busy. Work as well as fun.

I will make a promise to force me to complete the nebula tutorial.

‘The Nebula Tutorial will be on my website by Saturday 15 January.’

All the best.

Cog

Hey COG good to see you back and the ticker still ticking! Your site is looking great. It’s been a while since I visited. Keep us posted!

Hi Oxman

Good to hear from you too. I’m having a ball at the moment. Really enjoying making progress with Cog. It does take forever to produce even simple shots though so I have to be here for the long haul. Still ticker going very well now thanks and I will endeavour to keep the website up-to-date. Speak to you soon.
