 ## Limitations and Idiosyncrasies
 
-- **One channel/frame at a time**: for performance reasons, one channel/frame is streamed for tracing at once. Commands that require all channels/frames available simultaneously (e.g., [Multispectral Refinement](./manual#multispectral-refinement)) are not supported
+- **One channel/frame at a time**: for performance reasons, one channel/frame is streamed for tracing at once. Commands that require all channels/frames available simultaneously (e.g., [Multispectral Refinement](./manual#multispectral-refinement)) require [materialized regions](./manual#materialize-regions). 
 - **Fixed search algorithm**: the A* search algorithm is used for interactive tracing; the alternate NBA*/Fast Marching options available for in-core images may not be offered in Stream mode
 - **Cached image statistics**: Access to cost-function tuning and [image-statistics options](./manual#algorithm-settings) remains available. However, since _Compute Now For Whole Image_ scans the entire streamed dataset once, it can be _slow_ depending on dataset size and network/disk speed. Use _Compute Real-Time_ (the default) instead: It recalculates local statistics as you trace new regions.
 - **3D Scene recentering on click**: whether/how the view recenters as you place tracing points is configurable from the toolbar's options menu (_Never_ / _Adaptive_ / _Always_). _Adaptive_ is the recommended default for streamed data: it skips recentering for clicks that already land close to the focal plane, and briefly gates subsequent clicks after a recenter fires, giving tile streaming time to catch up

 [Big volume viewer](./manual#big-volume-viewer) and [Big data viewer](./manual#big-data-viewer) are at the core of Big-data support. Standard formats (TIFF, and anything readable via [Bio-Formats](/formats/bio-formats)) are loaded as regular in-memory volumes, with an option to downsample automatically if a volume exceeds the GPU's 3D texture limits.
 Imaris (.ims) files are supported via an automatically generated BDV-XML sidecar written next to the original file.

+### Non-pyramidal and Oversized Volumes
 
 BVV's 3D renderer requires a multi-resolution pyramid, and a single GPU texture has size limits. If the _Main volume_ does not satisfy these and BVV is chosen, SNT prompts you for how to proceed:
 
-- **Non-pyramidal N5/Zarr**: Choose _Build Pyramid_ to have SNT compute the coarser levels on demand (volumes that fit in memory are first copied locally, which may take a while for remote datasets)
+- **Non-pyramidal Zarr/N5**: Choose _Build Pyramid_ to have SNT compute the coarser levels on demand (volumes that fit in memory are first copied locally, which may take a while for remote datasets)
 - **Image too large for a single GPU texture**: This happens when a dimension exceeds the 3D texture limit of your graphics card, or when the volume has too many voxels per channel. You can choose between:
   - _Downsample_: Shrinks the image so that it fits. Opens quickly, but fine detail is lost
   - _Load at full resolution_: Loads every voxel into memory as a tiled pyramid. Requires substantial memory, and is a rendering only: it cannot be used for tracing
