![]() ![]() This parameter specifies the strength of this small scale turbulence. The Up-Res'ing post-process also adds small scale turbulence to the fluid that will create additional detail. This parameter specifies how much larger the resolution will be. ![]() When running an Up-Res'ing post-process by clicking the Up-Res button, the resolution of an existing simulation will be increased. the parameters in Simulation/Temperature, Density, Fuel and Burn). Simulation Steps for the up-res post-process as well as the channel parameters (i.e. When up-res'ing a cache you don't need to cache the velocity again unless you need it for rendering (for sub-grid detail or motion blur). Make sure you enable velocity caching when running the lo-res simulation. In order to be able to up-res an existing simulation cache, it needs velocity. The result will look pretty much exactly like the lo-res version but with additional small detail. Up-res'ing is a simulation post-process that allows you to increase the resolution of a simulation cache without running a full simulation at the higher resolution. While the differences won't be huge, they may still be undesirable after you got the overall look right in a lo-res simulation. Not only will there be more detail, but even the coarse shape of the fluid motion may be different. When running a simulation at a higher resolution (lower voxel size) it will take longer to simulate and may produce different results. ![]()
