How do I link objects to create a Linked Building?

Have the ‘Position’ tool selected in the ‘BUILD’ toolbar.
Click and drag to create a bounding box – everything that resides ENTIRELY within the box will be selected. By default, selected objects will show a yellow highlight. Ok?

Click the ‘Object’ tab in your ‘BUILD’ toolbar. Click ‘Link’.

If all the objects do not have the same owner, OpenSim will not allow the objects to be linked.

Find the object that is not owned by you (typically a facade, or building element copied from another build).

Make note of the object’s position and copy it. Click the first “C” to copy its position.

Make note of the object’s name.

You will have to ‘take’ this object by right clicking on it and selecting ‘TAKE’

The object will now be in your inventory. Place it somewhere. 

Click the second P to position the newly placed object based on the original position (saved on your clipboard).

Return to step one and select all objects for linking.

What format should I save images in for upload as textures and facades?

Textures should be uploaded as PNG files to ensure that ALPHA transparencies are maintained.

Save images as 24bit color PNG to ensure high-quality edges/transparencies. (As opposed to 8-bit which may cause issues with uneven edgest – OpenSIM will be modifying the image anyway)

Images are (typically) converted by OpenSIM to have an aspect ratio of 1:1, 1:2,
Images are converted by OPENSIM to a native file format for use within the grid.
Images are converted to the following sizes depending on their original resolution/dimensions.

You’ll typically get image dimensions of:


However, in cases of extremely uneven aspect ratios for images (such as very wide panoramas), openSIM will may make the width a multiple of the height. (eg, a 512×2048 image).
