Here is a quick and messy way to get that shape in less than a minute. (You will need to adjust specific parameters to fit your needs) but this should get you on your way.

Hope it helps Smiling

Well, I've done the low poly model with his UV maps. Smiling If anyone knows a better way to get the uvmap of the sphere, please, tell me! Smiling

Hope yo like it! Comments are welcome!

It looks pretty sweet!

Can you post up your uv's so I can see how you laid out the sphere portion?

Eii! Thanks @oxblood! I had done it, but I didn't get good results. 

@ceribal, here is the uv_map.

I divided the sphere uvmap in two parts. That's the way I got the best result

Thanks :)

Hm... I think that is going to be a huge pain to try and texture with everything uv mapped like that. 
Try something like this. Its easier, cleaner, and a snap to texture. Plus it hides the seam Smiling  AND there is only 1 seam Laughing out loud

Great job! I will update your top thread with the new content. When you get the final result, I will update the thread again Smiling

I just want to let you know that your UVs could benefit from being straightened, particularly the islands at the top that are almost straight, but not quite. This would eliminate stepping that will occur in your texture, which is noticeable in your render. In fact, you could even straighten some of the more organic islands. Some stretching will occur, but the elimination of stepping plus the ability to pack your UVs tighter will make your texture look better overall. The large island at the bottom for your sphere could be expanded to use the empty space at the bottom left. Yes, it will be slightly stretched, but it is minor enough that it will not cause issues. It is always good to utilize as much UV space as you can, especially if you want to show the small details from your high poly better. Smiling

I don't know if it's past the point you want to do this, but hopefully this will be handy information for you with your future models at least.

I really appreciate your comment @Kanaru. I'll be careful in future projects Smiling

This started as a test, but I really wanted to see the finished model. :$  I let myself be carried away by emotion Sticking out tongue


Thank you very much Smiling
