With the house model provided by Substance 3D Assets, this explosion simulation was staged in Solaris and rendered with Karma XPU by VFX Artist Travis Rainford, who also included a quick breakdown of the process.
The artist has also shared some details on the performance, mentioning that every simulation was run for around 144 frames. The RBD simulation took approximately 10 minutes with 10 substeps, while the main explosion simulation was about 8 hours with 5 substeps and a voxel size of 0.025, and the inner fire simulation took about 2 hours, also using 5 substeps and a voxel size of 0.025.
