Description: Again Miklos http://www.urhajo.tvn.hu/download/tarranian.zip model, this time without a blurred background.

The scene is lit by the sun and the MoonBlueGreySunY.hdr which I made on Rashad's request. Sun and HDRI-sun are at Az/X=40, Alt/Y=25. Settings are Quality 16, Intensity 1.5, HDRI-Effect 100, Linear 35. The stars are the Bryce stars, multiplied by a couple of flat and bent transparent objects with low refraction settings and a bent mirror. The nebulae are spheres with some volume material. Renders in less than 8 minutes.

This turned out really really well. That moonbluegrey.hdri was always great, but I think it is even better now with that bright spot. Adding the bryce sun is easy and very effective. Aside from a bit of angularity on the asteroids, this is a superb piece. Excellent! IBL can work very well in outer space!

Ah. Bryce's pathetic rocks. The stars look very good, but the texture on the ship is not tileable and the individual tiles are visible. Other than that it looks pretty good though.

Those IBL probes are working great too Horo. Thanks a lot.

Well, I have to agree and disagree on some things here. Lighting, is not really pushing the reality button for me. I don't think HDRI needs to be here at all. Only light from planet, sun and any light source on the spaceship itself. Also, the bryce rocks are pathetic I have to agree, any bigger then 8 pixles and they look very bad lol. Also, the rock texture of the steroid should be very different. A lot of those space bodies have ice and rock mixed, I don't see any specularity in this one, also I like to bump up the frequency of texture, this image here if it is 10% I would increase to 100-120%. and I would stay away from any texture that has some sort of wavy paterns, those just scream out fake! (unless the situation calls for a texture like that).
Also, on the ship I don't think tis a tiling issue, but a repetitive issue you would have anytime using a small image file as texture. I can't say for sure if this is a bryce material on an image file, but if it is I would also use some sort of cloud texture to saturate the repetition. The stars are ok, but those nebula/galaxies are not something you would ever see in space.

Lighting in space is tricky. Very tricky. I like the idea of being able to use a HDR for this environment, but then an "excuse" has to be found to explain away the "other light" - that is the light that is not comming from the nearest sun. So in that respect I agree with Gat. That being said I do like the balance of light in this scene even if the scene itself has nothing in it to "explain" where the "other light" is comming from. The rock on the bottom left I like very much, the texture scale and lighting are really working well together there (although it is rather too poligonal - as observed). Wings3D is the answer here, wings up some asteroids. I don't think there can be any disagreement over the issue there. I rather like the strange space nebulae things - although they don't look like things I've seen in space before - they do have and extraterrestrialness about them that is suited to space scenes (perhaps more fanciful examples than this one). The ship texture, I agree with Gat again. Other rock and stars fine no issues. The large rock in the fore - the texture seems a little to "large" again as Gat observed. The composition is good - however I would like to see more asteroids in the scene. So... good, but needs work.

gat the texture problem on the ship could be fixed by using a texture that is tileable, that seamlessly blends as it is replicated. Smaller texture that have not been made tileable will not do this.

Idea. What about if we attempt a scene like this in Carrara with Carrara's Global Illumination capablilites? Carrara is programmed to literally "bounce" light, so maybe it would know how to handle this situation. In space movies they use GI all of the time, however false it may be. In the situation above the only thing I can think of is that the bright sun should provide enough light to bounce around pretty efficiently on a white frosty asteroid like these, meaning the shadows would seem a touch lighter than total black, at least up close.

Carrara also uses radiance so that might not work. It also uses photonmaps. Carrara does not truly bounce liight, because that takes a long time, carrara takes shortcuts and fakes light. If you want a true ray bouncing render engine, then Indigo is the program to use.

Oh, and its true tileable textures match corners, but you can do that in Bryce just by checking tileable* in the material mapping options. Even if it is tiled you will still see repetition.

The stars turned out trully effective! Good going with the transparent objects! The angularity of the rocks has been mentioned already, so I don't need to point that out myself too. Although I like the David's idea to make more of them, and since those are bryce-generated objects, they won't be consuming a whole bunch of ram memory; of course making asteroids in wings is a different matter. The nebulae here look like a static charge. And I find this quite nice. Maybe if there were radials inside or just a little ambient in the material, things might level-up(?)
I still haven't downloaded the Miklos' ship, but it seems to me that it's bryce-made. So since the geometry of the model isn't that complex, I believe here a proper texturing is needed to get rid of the "toy-like" feeling. After all, the ship is in the center and attracts most attention.

Without IBL, the shadows are black. There must be a blueish planet behind the camera that is responsible for the light. The rather coarse bump on the main asteroid was choosen on purpose: to scale it down. This is not Ceres, just a chunk of rock. Miklo has an image texture on the ship, which I scaled to much smaller using the transformation tools. I like the way it turned out, partly square tiled and partly radial. But you may disagree. Yes, the nebulae are a bit strange but there are also strange filaments out there in real space. And the Bryce rocks are too angular. I should have done them in Wings.

Thanks all for taking the time to post your comments.
