# Troubleshooting the 3D explorer#

When viewing larger and more complex models in the 3D explorer on OSBv1, and depending on the computing load that the OSB cluster is experiencing (with multiple users for example), it can sometimes take longer than expected to load the explorer interface. Here are some general tips to follow if you experience delays when loading the project:

• If you see a white page with the text “Loading project …” but the explorer does not load, please refresh the page a few times (using control + r or F5 in most browsers, or the “reload” button). This re-initialises the explorer.

• After the 3D explorer has loaded you may see the Open Source Brain logo rotating in the page (either in the centre of the top left hand corner), this is the progress timer showing that the operation you attempted to carry out (for example: loading connections or recorded data in plots) is being processed. Depending on the amount of data being loaded, this may take a few minutes. If it does not load after a few (say 3-5 minutes), please refresh the page.
