Jawset turbulencefd for cinema 4d12/8/2023 ![]() ![]() ![]() To get an idea of how the modes differ, compare the histograms in the shader's mapping curve editors. The decision of which mode to use is mostly driven by your shading settings. It models the way dust slowly dissipates in air. This is the type of decay that temperature and density have. And the speed at which is drops will get slower and slower. Therefore the emission never drops back to zero - only very close. As the current value becomes smaller and smaller, so does the value that is subtracted. This mode works well for flames that have a sharp contourĭecay the burn channel by subtracting a percentage of the current value (of a voxel) in each frame. If you emit 1.0 into the burn channel, setting Decay to 0.1 in this mode will let the emission live for 10 frames before it drops to zero. Linearĭecay the burn channel by subtracting a constant value in each frame. The Decay Mode specifies which will be used. Specifies how fast Burn diffuses (see Temperature/Diffusion above for more details).ĭecaying a channel can be done by a constant amount or by a percentage of the current value. In this case, increasing this threshold allows the sim to keep the container smaller. However, often shading settings are such that low values aren't visible anyway. ![]() If this value is zero, no voxels containing temperature will be lost. If the Adaptive Container option is enabled, this value defines the minimum temperature that will cause the container will consider non-empty. Check this to enable simulation and caching of the burn channel. ![]()
