I have two terrains in bryce, each one has a texture aplied to it. I render them and everything is ok, then i group them, i render and all its ok, but when i open the texture editor, there is only one texture and no the 2. Is there any way to group the terrains and that each terrain have its respective texture inside the group? thanks.

You'll have to ungroup them to access each texture.

Or just select each terrain seperately. If you select several objects with different textures and then go into the material editor all the objects will take on one of the textures of one of the selected objects. So the word of warning...don't go into the material editor with objects of differents textures. Select each object seperately and modify the texture, you don't have to ungoup groups to do this. If you have 2 or more objects with the same exact texture and settings then it's ok to select all of them and go into the material editor.

ok, that ok, but if i need to copy the texture group to paste it to other diferent group, how can i do taht, if i do, when i paste the material in the group 2, only pasta one texture in all the objects of the group, is there any way to copy and paste the material fron one group with 2 textures to other group ?

No, only one texture at a time can be stored on either clip board.( the one on the Edit/Copy-Paste Material or the copy/paste function in the Material Lab ) But each clip board can hold a different material at the same time. The easiest way to copy/paste between groups with multi-materials is to select one object in the group and use the Edit/Copy Material then select an object in the second group and use Edit/Paste Material.

when you say > But each clip board can hold a different material at the same time. i dont understanf, sorry. Can you explain it ..

There are 2 locations where Bryce can copy & paste material. One is located on the Menu Bar ( Edit/Copy Material and Edit/Paste Material ) The other is located in the Material Lab under the Preview Window ( Copy Paste option ) When you copy the material at one location say in the Material Lab, you cannot go to the Edit/Paste Material and paste the material copied in the Material Lab. Visa versa, you cannot copy from the Edit/Copy Material option and go into the Material Lab and paste it. Therefor there are 2 different clip boards where the copied material information is stored. One for the Materials Lab and one for the main scene window. For what you want to do, it would be easiest if you use the Menu Bar Edit/Copy & Paste Material options. Since you can only copy and paste one material at a time, from one object ( in the group ) to another object in a different group.

Or if you want the same texture for both terrains then don't worry about only seeing one texture.
