Hello Rowlando !

to work with a big construction scene window
just click on the little triangle below the 5 balls of the tools
select photo : 768x512 that's better now !

to install free stuff, create a scene,  import the object
click on the triangle right of the word "create" the objets library window open
select the library you want to add in and click on the "add" word ! that's all now you can use your object
in all your future scenes

only the terrains can be exported from bryce, sorry !
have fun with Bryce
visit my gallery !
