rendering objects separately
Hey guys, I’ve got a basic object that consists of a few primitive shapes and such. Was wandering how I can set it to render so that each object renders out separately with an alpha channel?
I know about object buffers but thats used for an alpha/luma matte correct? Would like to know how I can assign tags or do whatevers necessary to allow each object to render out in its own image sequence with an alpha channel (that is, without having to go through the tedious process of toggling the visibility on for each object and rendering it that way 🙂
thanks in advance! Eugene

The most efficient way to do it is to render once and separate the objects in a compositing program using object buffers. If you want to do it all in Cinema, you can place everything under a null, turn off render visibility for the null, and then just turn on render visibility override (green dot) for the elements you want to render.

I should add that there are a couple of render pass plugins that allow you to store various states (like visibility) and then batch render, which could save some time. Render Elements is one: https://adamswaab.wordpress.com/category/3d-software/cinema-4d/plugin-development/render-elements/

great I’ll check that out thanks. But say if I was to place everything under a null then switch on the green override switch for the elements I want to render out. They’ll still render out as a single image right? Because basically everything in my scene I’d like to render out but have each element rendered out in its own image sequence.

Yes, you’d need a plugin to do that, or else save out multiple versions of the file and batch render them.

I see, and Render Elements is a plugin that does that for you?
