You can use the rendering mode of Mecabricks for that.
Select "3D Rendering" in the top left drop down menu in the workshop.

Here's a good video by @renderbricks that maybe could help you. https://youtu.be/AUICEW6Xnn0

Thanks! I can render now.But how to add my renderings to the library?

Go to the model in the library, click renderings, and then click the + to add a new rendering. 😉

But how do I download more rendering at a time?

You can only upload one image at a time. It is quality not quantity 😉

Oh no.Thanks.
