Hi everyone,
I'd really like to find more in-depth technical information on render logs, I was wondering if that info is available anywhere? Really quite interested in the "OpenImageIO Texture statistics" for example.
I've found this doc, but it unfortunately doesn't go into much detail.
https://docs.arnoldrenderer.com/display/ARP/How+to+Read+a+Render+Log
The main goal is to be able to tech check assets / spot unhealthy assets and shots in terms of render optimizations etc.
Edit:
"OpenImageIO ImageCache statistics"
- File I/O time -> Are higher/lower times something to look out for?
- - Redundant Reads vs Cache Memory -> If redundant reads are high, should the cache size be increased for better performance?
- - Tiles -> I'm guessing the higher values are more of the tiles being seen in shot? Is a higher or lower value something to keep in mind for any reason?
- - Total pixel data size VS Total actual file size, the pixel data generally being higher than actual file size?
---- Other: ---- - The warnings "displaced objects have very poor bounds. This can severely affect ray tracing performance." and "Scene creation was a significant amount of total time (57%). Consider optimizing this process first." -> Something to worry about?
- - The amount of "Shadow" ray counts generally always being one of the highest value, is the a normal occurrence?
shadow 7205071109 (3474.67, 345.41) ( 80.58%) ( 0.90) ( 9)
- - What does fairly high "light filter" values/percentage mean, in terms of Shader Calls? Is it that a lot of light decays and gobo's where used? What sort of render impact can those have?
| light_filter 12533780797 ( 6044.45, 600.86) ( 32.26%)
- - In terms of .ass file caches I'm assuming that the higher percentage of "reused" caches would mean increased performance and lower ram usage?
| unique (loaded from disk) 283 (5.93%)
| reused (found in cache) 4493 (94.07%)
Thanks very much,
Andrew
