...put an object (OBP) I downloaded into my scene?
I have it installed to my Bryce7/Presets/Objects folder but I don know if I import it; open it or merge it.
Bryce 7.1 Pro.
If it’s in your presets then it’s ready to go and should come up by accessing the objects library which is accessed by clicking the triangle to the right of the word create at the top of the Bryce interface. The only problem you might have that I can think of would depend on how you put it in your presets. I’m assuming you put it there manually? Many people, myself included, like to organize things on their computer by grouping things in specific folders. To illustrate lets take a look at how I might have organized objects. You already start with the folder presets/objects. Now if I had many objects from the same vendor I might want to group them that way, lets say that artist’s name was JSmith. So then I would have presets/objects/JSmith. If I just put the objects directly in that folder with no other sub folders then everything would be fine. Let’s say though that some objects by JSmith are buildings and some are plants. I would be inclined then to seperate those by having a sub folder under JSmith for Buildings and one for Plants. Yielding presets/objects/JSmith/Buildings and presets/objects/JSmith/Plants. Unfortunately if I did that I would not see any of those objects because Bryce only recognizes one folder level deep beyond the objects folder (same is true for other presets catagories as well). So just be careful how you organize things when manually bringing them into presets otherwise you might not be able to access things you put there.
Now assuming that isn’t an issue in your case the process of getting it into your scene is: Open Bryce, load scene, click the little triangle next to create at the top of the Bryce interface, find the desired object, select the object by clicking on it, click the green check mark at the bottom right corner of the objects library window. This will then return you to the scene with the object loaded into the scene. You may still need to use the edit functions to move it around or resize it within your scene.
