BW Modelling Tool on SAP HANA Studio issue

Issue: modelling functionality does not available when using BW Modelling Tool on SAP HANA Studio (Windows Desktop client) for SAP BW 7.5 on HANA. Of course, RSA1 does not provide such functions any more in BW on HANA.
We resolved it just by installing native Eclipse, applying SAP HANA addon over it and then applying BW Modelling Tool over it. This way we resolved issue on all computers of our team.
