Test - Procedural Vue Planetsby `priteeboy

Scraps

It may not be the most artistically breathtaking thing to show in your inbox, but don't under-estimate it - these planets were made using NO image-based textures at all! virtually made from nothing but clever use of filters and functions alone!

That's right, 100% pure Vue work right here

The function editor (not that I'm pro at this challenging yet powerful aspect of Vue but have spent hours experiemnting recently) can be used to create some stunning materials as these here which when applied to a series of layered spheres, can make very realistic planets! So imagine how much cooler this would be if I did work my Photoshop magic over it, but that would defeat the purpose of my test here

Some of the advantages of fully procedural materials include:
- Uses WAY less memory, each planet-object and their materials don't even use one MB of space (lol, bit of a pun in there)
- Dosn't get that "distortion" at the polar areas of the sphere that image-based textures do, so these planets can be rotated and viewed from any angle without weird "polar suction"
- Higher detail, since image-mapped textures lose quality fast as you approach closer, these do too an extent and become a bit blurry, but not in an unnatural "pixellated" way
- Easier to edit, rather than making a new map for a new planet all over again, the proportion of land to sea can be easily be changed, as can the colours of the planets, the level of cloud-cover and how swirly they are and so on.

This is a preview showing 2 of 4 planets I have made for a high-grade resource pack for Vue users that I'll intend on selling on Cornucopia (gotta get a store account first

) like most things there, it won't be expensive, but since this is an original idea that practically every Vue artist will wnat, hopefully it can reel in some pocket money for me, whilist giving Vue user's the best planets available to use in their sci-fi scenes (Most of the space-related stuff there at the moment is really dissapointing

)

A far bigger (and dearer) pack is in the making, it will contain these four planets plus a shitload more! things like Ringed Gas Giants, Suns and even nebulae that I have made directly in Vue - for Vue

Might move to scraps later, depends on how many faves it gets (I don't think it would get much

)

I know it's an old thread, but I stumbled here through Google. I can't believe there aren't more tutorials for this kind of thing.

I've had problems with Vue 'breaking down' with large spheres though; it seems to have a units issue (I can't believe they don't use floating point).

I've had to make my secondary planets really small (a thousand KM) and position them very close to the 'main' world.

What kind of distances were you using for this stuff? I know you lost the file, but do you remember?

Would have loved to see a pack on the Vue store.

When I was making these I didn't really consider the sizes as much as I would now. Since there were no other, physical things to compare them too, it didn't seem to matter even if they were just a few hundred metres across (which sounds about right

) Creating them in real-size seems impractical for Vue, but might be necessary in scenes that feature real, spherical-terrain planets as foreground element (even then, you can often "fake" a planet being closer or far anyway by changing its size and vice-versa, it only becomes an issue in animations)

Since I was using the mapping mode "object-parametric" for the materials - it didn't matter if I had to change the scale of the materials, since they would scale "with" the object anyway (I use that mapping mode for almost everything, on my personal plants and other objects for instance) since its great to avoid unwanted scaling issues in materials

Thank you!

Object-Parametric does seem to work pretty well, I'll play with that.

Thanks!

I know this is an old picture, but it looks great! I tried doing the same approach; I wanted a large planet hanging in the sky over a normal scene, but for some reason with some types of atmosphere, the procedural sphere doesn't show up. I'm still experimenting. I love AO, GR, GI, so that might be part of the problem.

Adding actual planets to a Vue scene can have very different results depending on the type of atmosphere. Standard atmospheres create very weird results. The planet will just be a solid-colour circle taking on the colour used in the fog/haze tabs. In the volumetric atmosphere it can look decent sometimes, but it will show through clouds even if the clouds are lower and closer. Really the best results are done using them in a spectral atmosphere since it "behaves" more like a real life situation.

If they disappear into the atmosphere then there could be too much fog or haze. Or the Aerial perspective may be set too high (but some is needed to help make the planets look like they are beyond the atmosphere, not in it

) Lighting shouldn't affect how they look. Only GR lighting will cause the back-side of the planet to also catch some unwanted reflected light. This can be resolved by not having an infinite ground plane or terrain

Hi, I just stumbled across this link in an effort to find a tutorial on making a procedural earth just exactly as you have. Have you been able post your stuff for sale on Cornucopia yet? Have you produced a tutorial by any chance?

I need to make a very large earth and get in close to the atmosphere. Obviously texture based earths start to look like crap when you try to get too close. I'd love to know how you created yours.

Keep up the great work!
Brian

I wish I could have created a Cornucopia3D store account to sell these. They would have been up by now. But previous attempts about trying to set one up were just ignored. I saw it as an opportunity to make ones better than these here so I did. I worked on creating heaps of planets of all types over a few months.

Then the file got corrupted and I lost EVERYTHING!

I have never been so disappointed in all my life. I don't have these anymore and it will be a long time before I bother trying to make them again

I will say though to use the mapping mode "Object-Parametric" that way the features will scale, move and rotate with the planet-sphere, rather than change (it's the only way you can get procedural materials to behave like image-based maps that "stick" to where they are on the object) The seas were created used a mixed material with a function to get a distribution of water and land materials

I just read through all the posts and found the one where you revealed the similarity to africa was purely coincidental. Here I thought it was. What a great illusion.

I'm in the same boat as infrah, just found out about vue.
was interested specifically for space scapes, this excites me as to the possibilities

U know of any decent tutorials? before i go looking.
Or u be willing to skim through some quick tips?

Vue can potentially be of big help in space scenes but it is mostly geared towards landscapes. There are some people who know what it takes to make good space renders in Vue but it is very tricky and I don't often see Vue space scenes that are any good to be honest

I have found a way of creating planets better than these old versions here now (though I lost the file, that was a grand waste of hundreds of hours worth of experimenting right there!

) But I haven't seen many others get quite the same results.

Still, the best space scenes I can think of rendered in Vue with no postwork necessary would be ones like [link] [link] or [link] to name a few, they wouldn't have been easy though since while Vue comes with a lot in regards to landscape resources - it doesn't have very good space resources, stocks or your own work is usually the best way to go
