Problems Reading Compressed Exr With Shake 4.0 On Linux

[user_deleted]

We currently use both Mental Ray and Air to render out EXR's in our production pipeline (with scenes genereated in Maya). We've noticed that EXR's rendered with Air will not load into Shake for Linux, unless they are uncompressed. Shake will try to read the EXR, but will crash with the last line of the output being:
"segmentation fault".

If we render our EXR files out of Air with no compression they come in just fine, but they are also much bigger files.
EXR's rendered our of mental ray come in just fine.

Has anyone run into this problem, or have a suggestion as to how we might be able to fix it, without resorting to rendering uncompressed EXR's?

Thanks.

What compression are you using and what version of openexr does Air use?

[user_deleted]

Air is using OpenEXR 1.4.0 (we're using version 5.0.17 of Air).
Any of the following compressions schemes crash shake:
zip scanline, zip block, Pxr24.

It's not even related to Air. If we render out files from shake using those compressions schemes that I mentioned as being problems, and try reading them back into shake, it crashes shake.

setting compression to RLE, or piz, or no compressions load the sequences just fine.

Thanks for such a quick replay btw.

I suppose the solution is to use piz or RLE compression, instead of the other trouble ones, but I wonder why it's like this. I also wonder if this is the case with shake for OS X?

Also, FYI, mental ray for maya defaults to RLE compression when rendering EXR's

I just noticed you are using Shake 4.0. Why not upgrade to 4.1? Openexr reader/writer was upgraded(4.0 was the first version to include exr). Lots of bugs were squashed with it.
