libtiff.so.3 needed

Wanted to install Substance Painter but libtiff.so.3 is needed.
Libtiff5 and libtiff-devel is installed.

libtiff3 is in Graphics Repo:
http://download.opensuse.org/repositories/graphics/openSUSE_Leap_42.2/x86_64/

What should I install I don t want to mesh up my already graphic workstation. Libtiff5 is installed but i guess we need libtiff3?

Could not install verification error.
libtiff3-3.9.5-2.5.x86_64.rpm:
Header V3 DSA/SHA1 Signature, key ID 4f311b1d: NOKEY
V3 DSA/SHA1 Signature, key ID 4f311b1d: NOKEY

Ignore it.

Is tthat smart could give integrity problems which leads to an instable system.

If you enable the Repo, you will be asked to trust the Key.

You install only one package, so you will not be asked for trusting the key…

Yes it worked. thanks
