I am the developer of Basemesh Temple. I use it daily for my own work here and I like it a lot personally. I designed it to be more like Zbrush’s sample projects which lets you click on a base mesh and start sculpting in sculpting mode with no setup or clicks required. It offers bunch of other useful functions (mask <- > selection conversion, easy remeshing etc) along with easy workflow so that you loose no time with clicks or saves etc, however it is not a kitbashing kit as of now.
Every basemesh opens as a new scene with a unique name ready to be saved. If you like what you have after working on a base mesh, you just
commit which then saves it to its final place. Think of it like a scrapbooking idea.
I might expand it to have kitbashing options in the future. I might also let users to be able to add their own assets if there is any request.
