If you're noticing that the hash step is slow when you're creating your tx file, then upgrade to a newer version of Arnold (at least Arnold 5.1.0) where hashing should be extremely quick compared to the rest of the maketx process.</P> Mon, 04 Jun 2018 15:16:53 GMT thiago.ize 2018-06-04T15:16:53Z how can I disable the SHA-1 checksum hashing in maketx(--hash) https://forums.autodesk.com/t5/arnold-general-rendering-forum/how-can-i-disable-the-sha-1-checksum-hashing-in-maketx-hash/m-p/11037651#M3871 Thu, 31 May 2018 15:41:22 GMT https://forums.autodesk.com/t5/arnold-general-rendering-forum/how-can-i-disable-the-sha-1-checksum-hashing-in-maketx-hash/m-p/11037651#M3871 Anonymous 2018-05-31T15:41:22Z Re: how can I disable the SHA-1 checksum hashing in maketx(--hash) https://forums.autodesk.com/t5/arnold-general-rendering-forum/how-can-i-disable-the-sha-1-checksum-hashing-in-maketx-hash/m-p/11037652#M3872 <P>I don't see any command-line options for maketx that control the hash.</P><P>Maybe you can use --sattrib name value to replace the metadata "oiio:SHA-1" : string</P><P>That's assuming you just want to remove the hash. I don't see any way to avoid calculating it in the first place.</P> Thu, 31 May 2018 15:53:22 GMT https://forums.autodesk.com/t5/arnold-general-rendering-forum/how-can-i-disable-the-sha-1-checksum-hashing-in-maketx-hash/m-p/11037652#M3872 Stephen.Blair 2018-05-31T15:53:22Z Re: how can I disable the SHA-1 checksum hashing in maketx(--hash) https://forums.autodesk.com/t5/arnold-general-rendering-forum/how-can-i-disable-the-sha-1-checksum-hashing-in-maketx-hash/m-p/11037653#M3873 <P>You really shouldn't be disabling the hash as that can cause slower renders.
