Acknowledgment

The sample Texture3D asset provided with this package was made using MRI scans found on this website.

Here's the process :

• selected the right-to-left gif
• rescaled it to 128x128 and extracted all the frames using VirtualDub
• used Unity's VFX Toolbox Image Sequencer to resample the frames count and lay them on an images sheet
• used a custom tool to build a Texture3D (basically create a Texture3D with the correct size then copy the images from the sheet as slices) from this sheet and save it as an asset
