Dalai Felinto 8d3cc431d7 Fix T41471 Cycles Bake: Setting small tile size results in wrong bake with stripes rather than the expected noise pattern
This problem was introduced in 983cbafd1877f8dbaae60b064a14e27b5b640f18
Basically the issue is that we were not getting a unique index in the
baking routine for the RNG (random number generator).
