  • Triplanar bump mapping - weird issue

    I've been trying to update my personal material library with triplanar nodes, and something i've noticed is that whenever i connect a triplanar node to a bump slot, it completely screws up the amount / type of bump effect.

    This object is unwrapped, and i tried to have a similar scale with and without triplanar, and indeed something is wrong. With a bump amount of 10, the regular bitmap without triplanar works as expected. With triplanar, it's like the effect is scaled by 1000%. For a similar effect i have to put the bump amount to something like 0.01 which is completely unusual. But even at that bump amount the bump effect is very weird too...

    Others slots works normally, but in the bump slot i have this issue.

    Any ideas?

    Would it be possible to send us one of those scenes for investigation?
    Thanks in advance.

          What do you mean ticket number? I directly sent an email via wetransfer with a link to this post and the download link. I can send in another way if you need. It was sent at 18:36 GMT.

            Our system automatically replies when email is received with six digit number which helps finding the request more easily.
            In this case you didn't receive that number since the request has been sent from wetransfer email.

            Never mind we have found it and we will proceed with the investigation.

              The issue is considered as a bug and reported into our system.
              Meanwhile you may use the latest official 3.40.02 versions, it looks like the issue doesn't exist in it.
