Hi everyone,
I have a problem with an assert popping up in ImageCacheImpl::check_max_mem.
On line 1952, ASSERT (full_loops < 100) becomes false.
I get this error on a scene with 4 meshes, having each 3 tiff maps
applied through different material channels. Each mesh has its own maps
=> i have 12 maps total. ( file size varies between 16 and 70Mo. Maps
are 8k*8k)
Depending on how much cache i set, i get the error sooner or later. If
i set more than 1.5GB, which seems enough to load everything, there is
no problem. I tried setting the limit to 1000, thinking maybe there was
really a lot of tiles to free, but it crashes the exact same way.
I run several evaluations at the same time ( up to 24 ) through a single
texture system.
I made a test and restricted the number of evaluations to 1, and it
worked. It seems to me that with several evaluations running, we try to
free memory but we can't because everything is used. So I uncommented
the log that displays the size of the memory freed, and i was suprised
by the numbers :
Freeing tile, recovering 67108864
Freeing tile, recovering 67108864
Freeing tile, recovering 67108864
Freeing tile, recovering 201326592
Does this mean the file has no tile ? Or a single tile ? In these cases,
shouldn't the image bypass the cache ?
Am I using the library correctly or not ? I'm not sure...
Michel
