Holy crap , dejavue or copy paste?

How dare you say this in a public forum. This is exactly,word for word what I was told earlier this week with quite insulting consequnces for myself.
You guys are out of control and need to stop attacking people when they dont say what you want to hear.

this has to be some kind of all time low, I am simply shocked and I hope that bjorn comes in here and moderates this quickly before I explode.

I can't speak for others, but based on my experiences, the work is getting more demanding out there and each year the bar continues to be raised. Work that was once reserved for high end film vfx has trickled down into almost everything--just poke around Vimeo and you can see smaller mograph shops and even single freelance guys churning out great stuff.

I think these rants are just a reaction from those of us who want to remain competitive. As Priest said above, I too do not wish to change careers and become a full-blown vfx guy, but I do recognize the need to (and would like to) strengthen those abilities. C4D has always been the tool of choice for the freelance generalist. What it means to be a generalist now and 5 or 6 years ago has changed. C4D has done an excellent job over the years keeping up with the changing needs of its user base, and I guess I (we) just hope it continues to do so.


well said, this sums up parts of the problem and my general experience as well..

Chi, can't the 10 million limit can be removed with the addition of a zero in maxon's code? That would solve the problems faced by those importing cached data and could be part of a small update for R14. If they don't want to feature it as a permanent number, a simple checkbox indicating the desire to raise that limit for special purposes would work.

..

This week I missed out on a killer project and sadly a lot of money too. I was all over the forum trying frantically to find a solution that rendered many particles quickly with dof and motion blur. I didn't actually exceed the particle limit, but ran into a lot of dead ends and basically threw in the tower.

C4D was the right tool for the Mograph portion of the work, no doubt about it. It was the right tool for all the other creative freedoms that C4D affords you. But it was wrong choice in the end for rendering the particle data. There's other work out there and I won't lose any sleep over the missed opportunity, it's just a shame the tools weren't there for the job is all, as it would have made a killer portfolio piece. Maybe next time.

I don't hold any resentment towards Maxon, it would great though if they got on board and paid attention to the countless requests to address these problems. As even solo artists would love to dabble in a more robust particle solution.

Thanks to Joel for the scene, I checked on the problem in it was a limitation of the Tracer. It was not supplying the spline data for hair to use. However, as requested somewhere else in this thread a way to cache the Tracer solve this and other problems:



The new update of pCache can now have a Tracer (or any spline generator) put in as the input Particles link and will cache it. It can then output this to a spline object, particles, points or from its own Generate tab it can generate splines/objects from the cached Tracer (or tracing of the tracer) plus render with Hair directly from pCache so you can use any standard CINEMA Material to render the spline and not just limited to hair materials.

Just a follow up on the original topic...

David was kind enough to look at my file and acknowledged a bug/limitation with it in regard to the tracer object, cloners and rendering hair. The tracer was not generating points in the picture viewer hence no hair was rendered. He also added new functionality to his pCache plugin which can now cache tracers and as a result, allow the hair to render.
"happy emoticon here"

(whoops--see above)

once again: thanks a lot david!

Nice teaser on the site David. Great update to PCache, very useful. Sure as heck beats re-sampling the tracer every time I want to scrub my animation.
