We simulate shock propagation in a wide range of core-collapsing presupernovae: from compact WR stars exploding as SNe Ib/c through very extended envelopes of the narrow-line SNe IIn. We find that the same physical phenomenon of radiating shocks can produce outbursts of X-ray radiation (with photon energy $3kT \sim 1$ keV) lasting only a second in SNe Ib/c, as well as a very high flux of visual light, lasting for months, in SNe IIn.
