Re: Pictures from Celestia

I have several additional problems. Where is the other object from the impact? Where is the matter from the other object, if the Moon is missing a lot of matter? Where is the lava on the surface of Earth, caused by gravitational effects? How can there be electricity on the surface of Earth after thi...

As I wrote earlier, use 3D Builder (free) to convert them to obj format.

Perseverance - the scale of things. The yellowish texture in the background has a 256k resolution, which is clearly not enough even to see the details of the landing site.

Re: Pictures from Celestia

Rover -> NASA mesh, you can download it. You can convert it with my tutorial (Method number 3). Use Anim8tor. Texture -> use the highest resolution Opportunity image, so you can have a 8192x8192 pixels soil texture. Use the NASA map for the landing site. Cmod landing site -> use Blender to create a ...

Re: Celestia.Sci news - what's going on?

Look what I found! https://arxiv.org/abs/2005.06671 To add support for accurate planetary ephemerides and interactive features, we integrated the engine into celestia.Sci, a general space simulation software. We demonstrate the ability of our engine to accurately handle a large range of distance sca...

Re: Long time since I posted

Welcome back! I think Selden, bh and JohnVV are still around from those days. You should try the new 1.6.2.2 version...it is quite stable and works nicely on 64 bit Windows 10 too.

Re: Procedural texture generation in Celestia?

it just means we have to find more textures I think it is much easier to make or collect 20 procedural textures than to implement a procedural engine like the one SpaceEngine is using. JohnVV can produce procedural textures. I'm sure he can produce 20...if we ask him politely! :think: In addition, ...

Can I ask how do you unwrap the original model? My Blender can't finish Smart Unwrap, it takes forever.

Re: Procedural texture generation in Celestia?

These commands would be very nice in my opinion when we are making an ssc file: RandomTexture "exogas or exoearth or exomoon or asteroid or comet" It would choose a texture from the pre-made collection of procedural textures EVERY TIME Celestia starts. RandomTexturePermanent "exogas o...
