That should not be the case: each view has its own set of independent options. How do you specify the options?

Sure: you can animate any number of views, each with its own options. If you want to visualise the same dataset with different options, instead of loading it multiple times you can create an alias, which will be memory efficient.

Don't hesitate to send us a more detailed explanation of what you try to achieve, tother with a sample .med file so we can provide more detailed explanations.
