Hey Friends

I'm looking for a way to create some open houses. I figured out, how to remove the door texture by editing the base asset, but the collision geometry still won't allow me to enter the house.
Is there a way to edit the collision geometry?
Or do you know any other way to create an open house?

Open houses aren't created with the same static pieces normal house are made with.

An example of an external home piece is the Shack kit.

There are a few different external home sets. You can create open houses with the whiterun kit, if you use the "both sides" walls, and tiled roof pieces.

You can't use the exterior sections created for the houses as they were created just to provide an exterior representation of the house with the interiors in an interior cell. They have one solid collision block. You have to build your structure from the interior pieces and just wrap around through the trans doorways or create your own open doorways with the corner pieces. The real problem is roof sections as there are very few in the game that are not buiit onto the solid building objects. Bethesda clearly did not contemplate using open buildings except in limited circumstances - the Dragonsreach porch and dragon trap are one example. The back patio on Proudspire is a minimal example. When they did use open buildings, exterior access is very limited.
