Learn about adjusting time stepping solver attributes.
- [Instructor] Like any area of 3D graphics,…liquid simulations are all about finding…the perfect balance between image quality…and resource usage such as computation time.…We can adjust Bifrost's time-based calculations…to prevent issues such as particles…going through colliders…and also to give us better overall motion.…Before looking at that,…let's check in on our master voxel size.…In the outliner I'm displaying Shapes.…I want to go into BifrostLiquidProperties1…and select the Container node,…BifrostLiquidPropertiesContainer…and open up the Attribute Editor.…
Under Resolution we have the master voxel size…which is currently at 0.033 meters…or 3.3 centimeters.…That's about one and a quarter inches.…This is just barely small enough…for production-quality results.…It's going to give a look that's pretty chunky…and won't have the very small fine details of water.…If I wanted to reproduce the look of water,…I would need to reduce the master voxel size…but remember that this will greatly increase…calculation time and disk usage.…
