  • Can't open previous vray material after updating

    Hi, impossible to open Vray Material Builder Node after updating to Houdini 20.5.332 and V-Ray for Houdini hash:8c90a65 from 02 Dec 2024 10:37 V-Ray Core 6.20.24 [2d08c24a] from 29 Nov 2024. The Vray Material Node has become a "Add" node with a "+" Symbol and can't be open. Very annoying to lose all the materials. Is there any known fix? Thanks​

    Hey creac ,

    This usually means the nodes themselves are missing, probably due to a corrupt installation. Are you seeing any errors in the console when starting Houdini?

    Best regards!

      Hi Gosho.Genchev, nope nothing. No log about possible corrupt installation. Vray is working normally. I can create materials using Material Builder, render.. no issue. Which install could be potentially corrupted, houdini or vray?

        Hey creac ,

        I was assuming the UI definitions were not being loaded properly due to a corrupt V-Ray install. If you're seeing no errors, that's probably not the case.
        I'll grab this specific build to check on my end, and message back in a bit.

        Best regards!

            Hey creac ,

            It turns out both me and a colleague of mine are unable to find this particular build. When did you download it? It's very likely it was deleted from the nightly builds a long time ago after we found issues with it.

            Best regards!

              Gosho.Genchev, not sure actually, in the last past 4months I would say.. but that's fine I will update with a more recent one and hopefully it will solve it. Thanks!

                    still have the issue after the upddate.. so basically all vray materials nodes have been "converted" to "Add" Node, and all Vray Node converted in "Merge" Node.. total mess. if anyone has an idea that would be great , so much materials t and setup that we can't loose. Thx
