Hi All, 

I have a strange issue involving Houdini not reading a UDIM sequence. The file names are ordered as BaseColor.1061.exr through to BaseColor.2994.exr I can read the files into COPs just fine when reading them as a frame sequence ($F) but trying to read the as a UDIM sequence into a Mantra texture node, I get "Error reading file". I haven't come up against this problem before, I have verified the files aren't corrupt and run through the sequence in Nuke. There are a few gaps in the numbers but I didn't think that would cause a problem. If anyone has any insight it would be greatly appreciated. 



Thanks, Tom
