Sculpted Type of buliding

In the edit panel-> object -> building block type -> sculpted, there is only an apple type. If I need a banana or a mushroom, do I change from the apple to them? Or I have to build them again? Thanks!

The apple is the default sculpted map texture. If you want to change to another shape you select another sculpted map texture by dragging one from your inventory to that rainbow colored square. Or you can double click on the rainbow colored square and then select a texture from your inventory. There are many free sculpted map textures available in world or you can buy them. I have some free ones at my store at

Thanks!
Does everyone has "sculpted map texture" in his inventory?
And "rainbow colored square" is used when choosing the skin of the sculpt, right?

the rainbow colored square is actually a sculpt map, you should have a few in your invintory library somewhere, what they are named tho i could not tell you. try going along to a free area like NCI in Kuula and seeing if they have a box of sculpties there with the maps so you can play around with them.

To make your own sculpts you will need to use a third party 3d program, but leave that for later. this tutorial might help you understand sculptie a little bit more:
