Abstract : UBE kosen was modeled in virtual space using Blender to improve the skills of participating members, cross-grade
communication skills and teamwork skills, as part of the activities of the voluntary activity group "E-Project" of the Department of
Electrical Engineering of UBE kosen. The participating members improved the technical skills through workshops for blender and
modeled some items in the school. Finally, we modeled the UBE kosen in the virtual space, and the visitors of the 62nd UBE kosen
festival experienced our modeling with a treasure hunt game. According to results of the questionnaire from the participating students,
it is found that everyone was able to enjoy their activities even if they are a beginner to the Blender. In addition, they improved
multiple skills such as communication, information collection, and so on.
