Komazec had great performances during the 1986–87 FIBA European Champions Cup season, and he led his team to the fourth place of the top 6 semifinal group stage.

After six years in Zadar, where he became the absolute leader and scorer of his team, he made the big step in his career for the transcription of the Greek League (which was at that time the best national domestic league in Europe) and Panathinaikos, of the head coach Željko Pavličević and the Greek superstar Nikos Galis.

In a year that began with ambitions to win the championship, for Panathinaikos and him also, won only the 1993 Greek Cup, in a final against Sato Aris.

The impression that he made by his performance in Varese, caused Buckler Beer Bologna, which was the dominant team of the Italian League the previous years, to buy his contract from Panathinaikos, and close a deal with him for the next two years, in an effort to replace the large void left in the team by Saša Danilović leaving for the NBA's Miami Heat.

In the summer of 1998, came the third and final chance for Komazec to make an important achievement in a great club of European basketball, as he agreed to play for head coach Dušan Ivković, at Olympiacos.
