Hello, kalwalt! The latest "3DCoat 4.9.69" for Linux doesn't require the dynamic library "libomp.so".
Please download it from here: http://pilgway.com/~sergyi/3DCoat/3DCoat-4.9.69.tar.bz2
But please note that "3DCoat 4.9.69" has been built under Linux Ubuntu 20.04 and I am not sure if it is able to run on OpenSUSE. Please check this test application which has been built the same way as "3DCoat" but it is much smaller: http://pilgway.com/~sergyi/TestStroke/TestStroke.tar.bz2
