Can I somehow combine normal map and bump map in luxcore...
I like using normal maps for bigger bumps and surface uneveness and bump map to give it some high frequency details.. But I cannot do that in luxcore..?

It should be possible, but I don't know if BlendLuxCore supports the kind of node setup required: you need to multiply or add the bump map by the normal map an plug the output in material bump map input.

Not sure if it matters, but I rather mix them after both of them are transformed to bump:
Re: combine normal map and bump map
Yes, you can mix/add/etc. bump map even before the bump node but normal mapping is a special case because it is an encoding scheme (RGB values encode the X/Y/Z displacement) so normal math operations can disrupt or product odd results on the encoded values.
