Textures

Converting Textures

The jp2 files used by the Secondlife client, are actually j2k files. These can be encoded by image_to_j2k from openjpeg. There is a Linux script or Windows script in perl, that does all the work for you. It uses imageMagick and image_to_j2k to make valid input files and converts them to j2k fileformat. It then renames the j2k file to jp2 extension, so these can be used within the viewer.

• Download the blender texture cd (as an example)
• Prepare your imagefiles (jp2 files with 16,32,64,128,256,512,1024 resolution and aspect ratio's 1:1,1:2,1:4,1:8,1:16,1:32,etc. are supported)
• Copy the jp2 files(including directory-structures) into the /opt/opensim/library directory
