Working with materials that sample RVT that will exist inside of multiple different RVT

  1. I use RVT for my landscapes

  2. I sample those RVTs for objects on the landscape to blend

  3. I have multiple landscapes (different levels) and now have a problem where the materials sampling an RVT texture are only able to sample from one of my landscapes

Do i need multiple instances of the same material? or is there some other smart way to switch RVT samples in material alone somehow for different levels?

Something like this would probably be highly unsmart

Yet another thing they never finished.
Take it up with support, maybe logging the 1000th bug report will get them back to working on it.
