Single animation solution

[LucentDreams]

did you look under radiosity? it basically uses one larger radiosity solution (takes longer to calculate) so that there is less chance of flickering, and you cna animate the camera and such without it having to recalculate everything for every single frame, so for long animations it will save time, for short ones its may actually take longer

Thx kai,

This info should help me greatly because I have to do an animation soon for a client. I have heard C4D has a tendency to show a flicker in movies when radiosity is used, so hopefully that box being checked elevates that problem.

BTW, I looked in the C4D XL 7 PDF help manual, but it didn’t say anything in the Radiosity section, even when searching with the find tool. Even the screen shots of that DBX in the PDF file is missing that radio button, so maybe it is somewhere else and I missed it. Or maybe it's an addendum in a read me file, or maybe my brains fried and I'll see it staring me in the face tomorrow:D

Thx for the feed back! :thumbsup:

to really get rid of flickering use stochastic mode

I was trying to use the single animation solution earlier on for both causitics & radiosity but it kept no recalculating the scene each time.
I tryed setting save solution aswell & I made sure I had first time only set but it sill recalculated it for each frame.

Anyone have any idea why? :hmm:

Cinema still needs to calculate a prepass for parts of the scene that weren't visible in the preceding frames, but using "single solution" will make subsequent prepasses much quicker than they would otherwise be.

Ah ok, thankyou :D

I was under the impression it calculated the whole thing and then used it to render each frame without having to calculate it again.

One other thing: single solution is only good for animating the camera. If you have objects moving in the scene it will mess things up.

The problem of stochastic mode is that it's reaaaallly slow! finalRender brute force mode is many times faster btw.

thx Adam, I had the same impression as Arrias, but this makes sense.

Hi Kai,

I’ll have to try this again. I’ve tried tinkering w/Stochastic mode a few times but I wasn’t happy w/the result I got. I guess I’ll have to fine-tune the settings. Plus as 3rd eye stated, it’s really slooow.

Does anybody here ever really use Stochastic mode? I’d love to see a comparison between the two modes of rendering w/in C4D w/in the same scene w/times comparing the two modes.

thx,

Paul

Yeah I've already found that one out :)

I was wondering, if I were to have a moving object in a scene but it's materials illum settings were set to not recive or generate GI & Causistics, would that still mean I couldn't use single solution even though it wouldn't affect it?

Stochastic mode is slower and typically has noticable noise, but the noise isn't as bad as the jittering, many artist like it as it can often be like filim noise. I like stochastic and feel that for animation its the only way to go realy, but its a matter of patience more than anything. I don't think a lot of people use stochastic, especially in the C4D world, but I like it.

--should consider booking a render-farm, id money allows.--
Finalrender might be faster, but good radiosity with little artifacts is simply rendertime-consuming (for an idea how slow it can be, render with Mentalray with good radiositysettings and find out, that a renderfarm is not so fast after all (at least 25 machines with 1900+ Mhz. we have had rendertimes of 7 hours for one (!) frame in PAL with all machines running (Mentalray can render buckets so they all can work on one frame)).OK, that scene was quite demanding (reflections and transparencies included)and looked very nice--
but we had to ditch the radiosity for the animation and go for a radiosity-fake with lots of lights (which took a time to setup but rendered in practically no time).
And the rendertime depends very much on the scene.
A cube flying over a plane renders very fast with Stochastic mode (but when is that needed?).
So, we need faster machines!Always!
