Hi,
Thanks for the info, I’ll look into it but I’m not inclined to spend more money ! ☺
I actually figured out my problem, while opening the project on the problematic computer. It was coming from a missing effect, Duik_spring, which is weird because I installed Duik, and it’s working on all computers. Anyway, I rewrote the Duik expression with custom sliders, and then… Tada, the render worked correctly.
So any missing thing will actually cancel the render, which sounds logical. I still wish there was a message or something to tell me what’s wrong.
