Head to the Resimulation tab and enable Resimulate. You'll notice that the contents of the grid suddenly disappear - Phoenix keeps separate sequences of cache files for the original simulation and the resimulation result. You can always disable Resimulate to go back to the original cache. The Amplify Resolution parameter increases the resolution of the resimulation grid. A value of 1.0 doubles the number of voxels for each axis, producing a total 8x increase in the voxel count compared to the original grid. If the original simulation grid consisted of 1 000 000 voxels, the resimulation grid will have 8 000 000 voxels. A value of 2.0 will quadruple the number of voxels on each axis for a total of 64x increase. The Wavelet Strength parameter controls the strength of the wavelet turbulence itself. You can adjust the Amplify Method parameter if needed. This controls how velocity is sampled. The Wavelet Nice method will produce a higher quality turbulence effect at the cost of simulation time. The Interpolate method can be used if the Wavelet channel is not exported.
Start the simulation as usual to resimulate with wavelet turbulence. |
