If the mipmap chain is incomplete, the developer should clamp the computed mipmap LOD index in the shader. We'll show this in the next update of the sample. Note: We're amazed the GPU hardware vendors haven't implemented this feature directly in silicon yet. It's extremely useful, even necessary at the largest ASTC block sizes. This is a form of "GPU texture compression-aware shading" or "GPU format-informed reconstruction".
