Yeah, so anyways, I tried starting a rifle model from scratch, completed it, exported and used it. However, in game, it was facing to right and was behind the player holding it. I suppose theres probably certain coordinates the model must be in order to be held by the player correctly? I would be extremely thankful if someone could let me know what those core coordinates are, and If theres a way in Slab6 to move the model to the correct area without having to redo the entire model.....

Any help is appreciated, and if I get this to work I will release the *original* but *generic* looking combat rifle for download.

What I did was mark the original voxels on the regular semi where the player hands touch, then built around those marked voxels. I had hell when making my arm cannon and busters, but this method helped me.

Tools>Adjust Pivots.
Took me literally four seconds to work out so I'm not going to write a tutorial or anything.

Exactly what Master Paradox said.

Also, here is the base model that I use for every one of my guns. The grip and trigger guard are correctly positioned in the players hands, the stock extends to the correct spot on the shoulder, and the scope is eye level.

@ Master Paradox, sorry but I'm new to this, Alright so as for the coordinates on the top, i matched up everything on the left side of the slash with the correct coordinates but I can't figure out how to change the numbers on the right side of the slash, I think this is why it's still coming out wrong.

So far for my models, I've just copied, renamed, and repalleted the current semi model, and then adapted the shaping, maintaining the barrel positioning and stock placement. I'm hoping to add arms to the models themselves in the future for realistic grips on different guns (plus a nicer-looking interface), but for now the easiest way to make new gun models is to adapt the default one.

The issue is now: the rifle is in the hands correctly, but now it's completely facing to the right

Change the pivot, under tools.

I've used ''Adjust pivots'' and the rifle is now the correct position in the hands, the problem is it's facing outwards to the right

Alright, sorry, I should've done this before, heres what I'm dealing with: http://imageshack.us/photo/my-images/580/riflemodelglitch2.png/

The X pivot is out of whack.
Go above the rifle and change the pivot on top.
