animation with moving objects basic workflow

[MikeeMax]

Hi,This is my first post here.

I searched the forum, but didn't find what i was looking for.
I just bought vray, and i ' d like to render an animation with moving objects.
Do i have to use "use camera path" option ?

This is what i do for the moment :
1 Light cache for primary and secondary engine. "use camera path" activated. save file to a specified location. RENDER ONE SINGLE FRAME."don't render final image" checked
2 primary Irradiance "use camera path" activated / animation(prepass) mode
secondary Light cache / "from file" mode pointing to the LC calculated in first step. RENDER ALL FRAMES. "don't render final image" checked
3 primary Irradiance "use camera path" unchecked/ animation(rendering) mode pointing to the first irr file calculated in step2.
secondary LC from file caluculated in step1 ."don't render final image" UNchecked
RENDER ALL FRAMES

Could you tell me if you see a big mistake here ?
what would be a proper workflow ?

Thank you very much

Mike

or if anyone could point me to a thread dealing with workflow for animation, that would be great.
Thanks

everyones got their own techniques. i think its what works best for you and that comes from playing with vray every moment you get and learning all the ins and outs of the software

i was expecting something more specific.... my bad. perhaps it's to me to be more specific.

which file should i point when switching to animation(rendering) after i have calculated all the irr maps with animation(prepass) ? is it the first irr map of the sequence calculated with animation(prepass) that i have to browse to ?

is it coherent to check the "use camera path" box when calculating the irr maps for very frame of a sequence ?

i thought "animation(prepass)" with "use camera path" checked would automatically calculate the irr maps for all frames. am i wrong ?(because here, in order to calculate all the irr maps, i have to render all the frames, not "single" as in LC calculation)

Thanks

as you said, you searched the forum, you must have seen many people discussing their own ways to do things

thanks,
i get it.
i found some usefull posts.

think of the lightcache and irr maps as being three dimensional views of how light is distributed - so you can have two irr maps for a room - one sees the left - the other the right - and to get the middle view the renderer can add the two together to work out how the middle lighting is distributed - it wouldnt be perfect as the more irr maps the more accurate the distribution

you can actually render a view from a new, different angle, using previously generated irr maps - providing they 'see' more or less what the new view sees

pre-render irr maps are often accurate enough rendered at a smaller frame size, for speed
