If you make props, please break them up into smaller bits that can be used individually. It's so sad that e.g. the Turin keep must always be used as a whole.
What I mean is: break it up into individual walls, make the stairs separate props, as well as any addons like a fireplace or wooden roof, etc. If you want to make some walls destroyed, please also include intact versions, it's so silly that there is the same hole in the wall in the Turin keep in every map that uses it.
If you make good new props that are included in cRPG, many people will love you.
