Re: [Oiio-dev] UDim Question Responses...

The first stab at the UDIM stuff is in OIIO master. I'm mulling over how to support Bruce's suggestion about UDIM-in-one-file, it seems like a neat idea. I agree with Jono that if DWA has already proven no negative effects in practice of lifting the same-data-window restriction on multi-part fi

If I recall correctly, when this stuff was added in 2.0, there were discussions about if this should be a requirement or not. It was decided to be conservative we'd start with the requirement, and then look to lift it in a later version. Looks like it's not lifted yet, but technically could be soon

Re: [Oiio-dev] UDim Question Responses...

Hi, thanks for the feedback, Bruce. There was pretty wide consensus, so I already have a proposed implementation that works as you desired (except for the multi-part UDIMs): https://github.com/OpenImageIO/oiio/pull/1426 Also a companion PR for peo

Hi Larry, We wanted to provide you our answers to your original UDim questions listed below. We're all curious to get your thoughts. Thank you! * What text should indicate that it's a UDIM texture and which will be substituted with the tile number? ""? "%04d" or some other explicit format indica
