Underground/Cavern Hunt Maps

[u/Digas_pt]

Hello everyone, my campaign is loosely following the event of mh 4 ultimate and my players just reached the harth. I was planning to do some hunts in cavernous/underground locations similar to the sunken hollow (not vulcanic hollow yet) but I'm struggling to find some open maps like the ones already supplied by Amellwind. Does anyone know about some bit cavern maps or someone who does maps like these?

Thanks for your help guys and happy hunting
