Hello, everyone,
I'm implementing Volume Rendering using [this](https://github.com/mlavik1/UnityVolumeRendering).
And then, this example code uses the `tex3dlod` function to sample 3d texture.
When I use other function to sample 3d texture for example `tex3d` or `tex.Sample`(https://docs.unity3d.com/2019.4/Documentation/Manual/SL-SamplerStates.html), compiler requires loop unrolling.
`tex3dlod` don't reqire loop unrollling. What is the different criteria to `tex3dlod` and others?,Hello, everyone,
