Abstract : UBE kosen was modeled in virtual space using Blender and Minecraft in order 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 were modeled in the UBE kosen in the virtual space, and
the visitors of the 61st 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.
