How to merge EXR files with sam?

[Fredrik Averpil]

Hi,

I’m new to Tuttle and sam and I’m trying to simply load EXR files, merge them (using “add” or “over”) and then write to a new EXR file.

But I’m having issues with just reading an EXR file. This is what I do, which results in sam-do.exe running forever, without completing:

sam.bat do tuttle.exrreader C:/tile.001.exr // tuttle.exrwriter C:/test_output.exr
getRegionOfDefinition 4961 x 3508
[2014-09-22 16:21:46.160763] [0x000025e4] [info]            >-- C:/tile.001.exr

What am I doing wrong?
I’m on Windows 7 with the current production 64-bit build.

Regards,
Fredrik

Hi Fredrik,

Good to hear you're using TuttleOFX ;-)

Is it possible to test also without mention the drive C:\ ? something like:

sam.bat do tuttle.exrreader C:/tile.001.exr // tuttle.exrwriter test_output.exr

Do you have rights in the C: folder ?

Cheers,

Hi Marc-Antoine,

Yeah, I actually found out about Tuttle just in time for Siggraph but I was unfortunately unable to attend the BOF. Too much going on at once! :)

I completely left out mentioning C:/ or C:\ and that still did not work. The process seems to enter an infinite loop as the thread is active and never exits. I have to end the process through the task manager. Also, in the task manger, I can see my 8 core machine reports that sam-do.exe is stuck at 13% CPU before terminating the process. So the process is not idle.

Yes, I have rights in the C: folder. Initially, I tried to read an EXR from our file server and write it back to the file sever. But when that failed, I copied files onto my local disk and to see if that would work better. But it didn't work at all either.

Not sure what could be going on here.

Regards,

Fredrik

And not sure who it will solve the problem, but can you try with sequences like:

sam.bat do tuttle.exrreader C:/tile.###.exr // tuttle.exrwriter test_output_###.exr

Unfortunately, that doesn't work either. The process just never completes. I tried removing the numbers from the filename too.

Fredrik

Hi,

This issue is already registered:

https://github.com/tuttleofx/TuttleOFX/issues/213

This is a Windows specific trouble. We work on linux and use macos sometimes... So the windows version is not tested a lot.

We will have a look and come back to you.

Thanks Fabien, that would be awesome.
