When working between Cinema 4D and After Effects, you generally have two options: render files from Cinema 4D and import them into After Effects, or use the live 3D pipeline to render C4D projects as layers inside After Effects. mamoworld CINEWARE Proxy lets you toggle back and forth between the live pipeline and rendered proxy files.
You can start working with the live pipeline and render proxy files in the background. Once the background rendering is done, you switch from the live pipeline to the rendered files, and all modifications made in the meantime are preserved. When you need to modify your Cinema 4D project, one click switches back to the live pipeline or updates your proxies to see the changes in After Effects.
CINEWARE Proxy also works with existing proxy files rendered by your method of choice, and it automatically learns your file naming conventions. Load one file and the others are found automatically, and it remembers your habits for future projects. It supports multi pass rendering, and background rendering requires BG Renderer Pro.
