Voxel Realistic Scripting Explode v0.01
This asset helps to create an explosion that is not an object in the area for destruction. Instead, the script refers to the radius position of objects. This will be very helpful if the project does not need to blow up the object and its parts, which can be accessed from a script. Explosions are very realistic and simple.
