animating with rpcs

[skeay]

Hello,

 

I have a question about animating a scene with rpcs (not too sure where it should go-I hope this is the right forum)

 

I have a scene which is 900 frames long, starts in a carpark and moves away-200cars in the carpark.

Each frame takes approx 13mins to render (too long) its because of the rpcs (take about 10mins to prepare)

so my question is: can I turn the rpcs off for a section? -after the first 200 frames you can't see the cars anymore.

 

I've been playing with visibility track but I can't work out how to add a track to an rpc object-anyone know if this is possible? and will it stop preparing the objects each frame?

Or, is there another way?

 

Thanks very much for your time I appreciate any input.

ok not to worry it is figured out- track view visibility seems to be the way to go.

still

can u tell us the method that finally worked

because for me its something even i have been trying but havent been able to do it

 

Thanks

well I worked out that using track view (dope sheet) visibility track worked. - i'm new to it but it does the trick- So a key at frame 0 fully visible, a key at 200 visible,201 invisible, 900 invisible. and object properties objects set to by object. It worked best with scanline although I'm working with mr so will continue to experiment.

so what happens is for the first 200 frames the rpcs are prepared + rendered, and then the rest they are unrenderable so not rendered.

 

Will post more results as I find out

can u post some screen grabs to support it if u have time

 

thanks

ok, but note these are only to show the process, no finished images.

 

the circled bits relate to -

 

cars-group making track easily applyable

by object- make sure the group is rendered by object or it won't work

visibility track applied by dope sheet under graph editors, select the object; cars, then menu; tracks-visibility tracks-> add

 

i hope this helps
