Hi,
It looks like channel names in files are truncated to be 31 chars (plus
trailing zero) maximum. That seems to be defined in ImfName.h.
In Blender we make use of the features as described in
ImfChannelList.h, for image files with many channels to group them into
nested layers. Unfortunately the maximum of 32 chars seems to be for
the total name, not for the individual nexted parts.
For example; in Blender you can define per render command:
- Layers (geometry based, like foreground/background)
- Passes (shading based, like per Lamp or Combined)
- Channels (R,G,B,A or X,Y,Z, etc)
I get errors reading back files with a channel named like:
Characters_and_platform.Combined.R
Which is just 34 characters...
So, is this limited naming behaviour as expected?
Thanks,
-Ton-
