http://www.space.com/images/4Moons_02,0.jpg I have tried to no avail to reproduce these images in Bryce, but end up with squares inside the boolean operation. I am trying to make multiple layers with multiple textures to show a planet like in the link above. Can anyone tell me how to do this that they have tried and it works. Thanks

Hi Vile. I'll give this a try, although I'm not worthy of the "expert" title. Let's work on the example in the upper left corner from your link. Create your planetary sphere and assign textures, etc. Next create a cube with one corner poking into the planet center. This will be the Boolean subtraction, or negative object, when they are joined. Perform the Boolean operation. Now create a new sphere for the planet core and assign textures, etc. Position this sphere in the exact center of your first sphere. You will still be able to see the cube after the Boolean operation, but when you render, it should resemble the diagram you want. Let me know if this doesn't work, and I'll create the scene for you and email you. Good luck! P.S. If you want to have other layers, create all of those spheres with textures and nest them inside each other, then group the whole shebang with the cube and subtract out the cube. Then add the last sphere for the core. May the Force be with you.

Well I did this as an exercise because I suck at booleans. This consists of a cube and two spheres. I know it's not quite centered, but it was just an exercise so perfection wasn't my aim. =D 1) Create sphere. Make positive. 2) Create cube. Shorten to half of sphere's height. Make negative. Group to check effect. 3) Create sphere. Resize to create core. Make positive. 4) Select all. Group.

Ah it is easily done with one layer but what I am trying to do is multiple layers here look at this. I have 4 layers here but not the way I want them. I have all spheres positive except the core, then two squares bisecting negative. but do you notice that it doesn't do the layers quite right. Try mor then one layer and let me know how that ends up...I have been bugger'n with this for awhile (no offense). But my boolean is not that bad lol

Any reason you can use texturing to get the effect you want?

I take it this is the effect you are trying for? 1. Create sphere with texture you want and set positive. 2. Create cube add same texture as sphere and set negative. 3. Group sphere and cube 4. repeat steps 1-3 for each layer. 5. Create sphere for core When you are finished you will have 3 seperate groups(in my example of 3 layers). Each cube has to have the same texture as the spehere it's grouped with. Hope this helps.

Looks great. Glad I could help.

Like I said - I don't claim to be an expert! Nice work there, kieraw, Aldaron and Vile. I dub thee Knights of the Bisected Planet, with all due rank and privelege thereto associated... And you gotta show us the finished product (esp if it has anything to do with Star Wars...drool...)

It was actually just a learning project. I am however working on a New Star Wars image should be done soon.
