hi
when we try to use animation rendering something very weird occurs and render imap in black
A yes, method(described below work a lot of times, but a few times this happens) works very well
B files exist, and they weight 5mb each one.. then they are not empty
C is the same camera, same geometry than prepass scene
D yes, rendering irradiance map single frame and lightcache has good lighting results
i am attaching 3 frames
A the animation rendering starts with the B frame, calculating single frame in olightcache
B the lightcache process
C a sample of the single frame rendering
the trouble is, the method works (yes, but i need to try where is the trouble in getting irradiance map that returns black spots to rendering)
to ensure it, i did a test with a lot of possible troubles :
A moving a object after animation prepass :: ok the object appears weird but the scene renders well in other parts
B moving camera, changing angle : ok, no problem
C deleting some files of the irradiance map files, such as the impa of the frame 26, 100 and 125.. ok, not problem, vray interpolates between them
D there is somenthing that is making that those imap in black appears
could anyone help me???
thanks guys
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
method we use and it works very well
we are using this method with successful results for animation with characters
stepA
irradiance map / high settings /animation prepass / saved
lightcache / lowest settings / flythrough / not saved
stepB
irradiance map / animation rendering
lightcache / highest settings / single frame
why?
1st, you cannot save an animated lightcache
2nd, if you save lightcache and during rendering, vray cannot find in lightcache data to render a glossy reflection WILL USE BRUTE FORCE and rendering will last 10 times more
3rd if you calculate lightcache in single frame with very high settings you are spending a few seconds or minutes instead of 10 times more rendering from a lightcache saved file and rendering glossies internally with brute force
