These elements can be allowing particles to pass through like E-wall. 正在重建 /PowderToy/3/115.html ... Element number 115 (INVS) usage: * .tmp = minimum pressure threshold. * default value = 4 (some as sim_max_pressure) * Invisible to particles while under pressure. * turns PROT into NEUT. 正在重建 /PowderToy/4/192.html ... Note: "PINV" is experimental. Element number 192 (PINV) usage: * PSCN activate, NSCN deactivate. * Invisible to particles while activated. * .tmp4 = another pmap (try creating a second pmap)? * Note: This element is pressure-insensitive.
