Strange render times

[Tommy L]

I have an animation with a pre-calculated irradience map (muti-frame incremental every 10 frames). When I render a test frame, it quicker to run the irradience map on 'single frame' (7min21s) than to load the pre-calculated map (7min31s).

I know the time difference is minimal and the main reason for the pre-calc is to prevent flicker, but I wondered if anyone could shed some light on why the render time is not shorter when its already got the light calcs?

Tom,

 

thats really strange... i've had this same problem my latest animation??? although the difference with mine was more like 30 sec to 2 hrs?

 

have to say tho i've not got to the exact root of it but a few things to try, that i did to rfix the problem are:

 

redo your precalced irr map... it could be corrupt

 

do you have any xrefed geometry in your main render file?? if so merge it (only mean xrefed viz / max files)

 

i think my problems came from a combination of the above as it was a little hit and miss regarding when the render time issue occurred.
