I'm a complete n00b with the program. I just wanted to render a simple model as a PNG with a transparent background.
Spoiler:I looked at a couple of tutorials online and they all told me to go to the render settings. The problem was, the options that they told me to look for were not there and when I found what looked like the correct option elsewhere, it was greyed out. The option is just a simple check box saying "Transparency" which I want to enable for PNG output.
Eventually I found a clumsy work-around. I created a project in an older version of Cinema4D, enabled transparent rendering, saved it, and then opened the project in the newer version. Voila! the option was now enabled. So, I was able to get my image rendered (see spoiler), but I'd rather not have to go through that process again.
For info, the versions that I have access to are:
r11.5 (old, but simpler, quicker and easier)
r18 - really only useful to me because files saved in version r11.5 cannot be opened in versions newer than r19. So if I want to upgrade a r11.5 file to r21, I have to open it in r18, save it and then I can open it in r21.
r21 - the newest version I have access to via my work. I *think* the program is up to r25 now but r21 is newer than r11.5 (obviously) and has more features. However, it is more complicated and, importantly for this thread, I can't seem to find how to enable transparent rendering in it without going through the daft process outlined above.
So, anyone know?
