Smoke-Volume is too noisy

For some reason the RaymarchVolume is quite noisy. This might be caused by the jitter which could be finetuned to reduce the noise while still removing any artifacts.

Start by locating the RaymarchVolume implementation and the jitter logic; the issue does not name files or tests. Compare the current smoke volume for noise and artifacts while tuning the jitter. Done means visibly reduced noise without reintroducing artifacts, but the issue provides no automated verification.
