i’ve got a very very simple look on this competing between cinema4d and other renderers.
-
can c4d-renderings look really photorealistic? yes they can look more real than reality (maybe you know what i mean, because we often dont realize some effects and visual impressions in the real world, which a rendering holds us under the nose (or before the eye, like you see it).
-
is c4d fast? of course it is. competing it with renderers of high-end 3d-software like maya and 3dsmax, it kicks out their basic renderers. of course, maya got mray, 3ds got final renderer and brazil and more and so on and so on, but AE costs only about 400 $ and cinema 4d basic about 800 $, makes 1200 $ and that’s what you would pay for brazil.
-
is it stable? yeah man, i knew 3dsmax to get crashed so often and to use such an huge amount of systems ressource, this counts for maya too.
my resume: c4d cant compete with PRman and Mray, but just take a look what you can do with cinema4d for that price - should tell you more than any other argument. we have included general GI, then comes especially hdri-support, which is not that kinda industrial rendering option, but for a freelancer its great 
thats why i render with cinema4d - it’s great and i got it together with the programm, and i’m able to realize anything in it - so i dont need Mray.
i dont talk about character animation, or about lack of modelling tools. thats not the topic and because i’m not the animator guy, even not the texture artist (but i read “c4d 8.2 - ein workshop für profis”, because i’m german, and i first started to bodypaint, just to fall in love with it).
ok, the ThinkingParticle thing and the COFFEE thing are hard to use for me, cause i’m really not the coder guy (just HTML, and lil bit of Perl, SQL and PHP, i would called it advanced nothing-knowing), but thinkingparticles seem to me to produce kinda really phat and nice animations.
i tried character animation in cinema4d, and i chose to buy MotionBuilder if i ever should want to do the animation stuff.
but for the modelling part: i dont have mesh surgery, because i cant afford it. i even dont use diTools and so one, my only used plug-ins are some organization helpes cause sometimes i seem to be the 200 objects in a scene guy, and they all are called "Polygon-object, polygon-object1, polygon-object2, and so on, and thus i needed a solution for this lack of discipline). but i like the modelling flow with c4d. in max, you have some great and really really mighty tools, but for me (thats MY opinion, worx for me but i never reflect it on other people’s preferd workflow) c4d is not only working, its kinda great fun to work in it, and in max for me its more like work, based on my disliking of max’s interface, where i would say c4d has one of the most clear, ergonomic and easy-to-use interface, but ok, you say it, it’s just a matter of time to rework any interface cause every big 3d-package has the option to build your own one.
mainly, what i dislike, is that lots of max and maya users look down on c4d-users, once a max user asked me with what i did a certain work which he liked really much. i said thats c4d, and he instantly, i mean just the time to write it, repeated: oh, c4d…thats not much of art because its easy to do in c4d.
what should i say to this, someone complaining to me that a certain 3d-solution is not as good as his because some things in it are easier to realize cause of better built tools for it?
thats a major problem, its kinda C+±people looking on delphi-coders, thinking c++ is the big deal and delphi the kiddy n00bie stuff.
