Comparing total feature set of Carrara and C4D is not possible or practical. But I don’t think it is too far fetch to compare similar features between the two. Multi-pass render is in both and Carrara’s is not bad. It just has bugs or a bug.(*see comment below.) The images also need some anti-aliasing and some smoothing and they would match C4D which is what I was trying to say is just a little bit of polish and Carrara would be the bomb. I would not have any reason to look for other solutions. I think Carrara is so close to what I want it to do but alas I have to wait for bugs to get fixed which could take years or not at all. For still images, I think Carrara can’t be beat in this price range but for animation it is too frustration to fight.
I don’t think we are too far off in what you or I want for Carrara, polish the feature set it already has. Make the ui better. Give a better time line or dope sheet. I personally want a content rigging script to give any poser/daz/genesis figure a GUI for faster posing. Make the features work as expected. Fix bugs in a timely manner.
But improvements to existing features and fixing problems does not pay the bills. (I think Daz has even said that) I would argue that updates if it was done on a regular basis would make a difference. Because I would trust Daz more to come out with a better product and feel more comfortable spending money with them. I think others would feel the same. I just hope things will change and that Daz will deliver a solid Carrara 8.5.
And if Daz proves me wrong I will gladly eat crow. Just add some cajun seasoning and it will taste like chicken.
I think that is right on how Carrara is calculating the depth pass now that you have said it and from what I have seen in the renders. Maybe Carrara is forgetting or miscalculating the depth pass from 1 frame to the next. Instend of something like C4d where it is a constant calculation from the camera.
