Click the Redo previous render (Krakatoa) icon - the individual particles become a bit less pronounced, but there is still a bit of shadow casting from particles onto particles:.Change the Final Pass Exponent to -5 and leave the Final Pass Density at 1.0.Reducing the Final Pass Density from its defaults of 5.0 and Exponent of -1 to 5.0E-3 or 5.0E-4 does not change the result at all!.This is why we will have to reduce the Final Pass Density multiplier of Krakatoa a lot more than in the previous tutorial where the Buddha statue a was significantly larger object.This is because the per-particle density will be distributed into a much larger volume.But if the same particles are simulated as a larger cloud occupying a cubic volume of 10x10x10 units, the average spatial density will be 1000 times lower per cubic unit. ![]()
