I redid all of this and doing it a different way .. went back to an older save to wipe 2 1/2 hours of work .. But going to leave it for your viewing. (I save the game as I do different building parts, so I have something to fall back to.) helps with crashes.

But still there is an issue with snapping .. some go with No problem and Others are telling you to stick your head in the MUD _ Lol .. No, I don't want to go there.

I do not know what is causing your problem. I'm going to try building a structure like the one in your pictures and see if I can get it to happen for me. That will help me figure out the problem.

What order do you put the pillars down in? Do you do a whole row or a column at a time? I want to imitate what you did as much as possible.

Good day Xylch ..
When I was doing it .. to be honest both ways .. first time _ laid a roll and then came to add second roll ........ next time I put down the first 1 and then tried to add 1 on top .. like I said some would and others would not.

On the Rebuild I found that, if I put down some ceiling pieces on top of them _ connected all with the ceilings _ so that you had a roll going over them .. and .. then they would go into place.

BUT .. once you get it all working together, it does make a great looking wall .. just takes alot of time.

Just strange that they are so hard to use at times.

PS: ARE .. the wall foundation pieces suppose to attach to them ?? If so, I could not.

I did some testing with the pillars and I noticed when I built on sloping ground, I reached a point where I was below the snap points of the previous pillars. I could still place pillars in the ground, but they might not be aligned exactly with the other ones. That is probably causing collisions on the upper row. Attaching them to ceilings keeps them aligned properly and avoids this problem.

Working with snap points is still confusing for me. Except for fixing the ones from triangle floors to pillars, I have just copied them from standard elements without changing them. My pillars have the same snap points as vanilla pillars and I do not think those snap to floors.

I think the best way to understand them would be to make a new element and give it its own snap points one by one. I have already found some things in this game that to me seem unnecessarily complicated, where the engine allows a simpler implementation than what has been used, and I wonder if snap point might be another. In any case, I need to learn more about snap points before I can fix the problems you have been having.

Good day and thank you for looking into it. Have a good weekend.

Question .. I know you have .. half walls in wood and stone .... Can it be made into a header type half wall .. in others words turned upside down _ used at the top .. is it possible, Why I ask .. is it could be very useful at times in roof building (instead of having to use a whole wall).

This mod makes it worth while to play again, never really liked the Vanilla stone and we have interior wood walls when needed.

Now .. I like the NEW Window Option. Looks Great.

Good day Xylch

IS there a way to make a Porch roof "guess you would call it a half roof" for player that want to add porches to the building ..
I have seen some vanilla ones in game stuff that Atlas did .. but didn't know it can be done as an add-on and maybe post to support something like a door frame , but smaller _
Just wondering

Something that could attach to building or a roof section for a 2nd floor setting.
