Did you make the blast wave radius a real size, or did you cache it and then increase the size?

I made the blast radius a compatible size with the mushroom cloud, and then once I cached the sim I was able to adjust the blast radius scale. However, once it's cached the resolution remains the same so if you increase the scale too much it will look bad.

@@jrffe yeah i know. I did something similar, the same atomic explosion (or rather the blast wave from it), but I ran into the problem that the simulation is very difficult to scale up. If I added the radius of the shape (which I had as a ring) and added velocity, and also increased the size of the world, the particles stopped being displayed at all. I couldn’t set the quality of the simulation higher than 200, because unreal crashed all the time. As a result, I had to write the result to the cache and increase it 10-20 times. Naturally it looked so-so, but I haven’t found an alternative yet.
