Yes. I am afraid that 3D chart exports are not possible at the moment.

As far as I understand ECharts, it uses WebGL to render any type of 3D chart. (See https://echarts.apache.org/en/feature.html#gl.) This means that WebGL support must be provided for Node.js somehow, but I am currently not aware how this can be done in such a way that ECharts server-side rendering can use it. I am not even sure whether this is possible. If anybody knows more about this and could share some information about that topic, that would be really helpful.
