Game Asset Creation: A Simple Crate


Simple Crate Model

This week I created a simple crate asset in Autodesk Maya. To start my project I had to adjust the scale in Maya so that when the asset is imported into the Unreal Engine it is in proper scale.  I set my length and width to 200 units and my grid lines to 100 units.  I also set y subdivisions to 10 for easy snapping and I put some simple coloring on my grid so that it is easier to work with. 

Adjusting Maya to the Unreal Engine Scale

Then I began to create my proxy crate in which I made 100 units all the way around and checked it's scale to the mannequin.  The Mannequin is about 6 feet tall.  To create my proxy I did some simple extrusions. I then exported it and gave it a collider.  I noticed that the lighting on the crates were creating weird shadows so I brought it back into Maya and fixed it's UVs before re-importing it into the Unreal Engine.

From here I began to create a more high poly crate that has details.  To begin I used a cube that was the same size as my proxy and scaled it down to that it was the same size but was thinner and fit the face of the proxy.  I used some simple Booleans to create the frame and beveled it and then created the smaller pieces and gave those bevels.  For the piece that goes across I duplicated my Boolean and created a face and from there I used my multi-cut tool and deleted the faces I did not need.  The I extruded it and beveled it.  I placed it and scaled it to fit on the crate. 

Proxy for Crate Details

To continue, I grouped, named, duplicated and rotated the first face to create the other faces.  Some of the faces a bit different weather they don't have the middle piece or they need their edges snapped so there is no inter penetration.  This allowed me to create my gaming asset crate.

I then began to prepare my crate to be exported into it's next journey into ZBrush! I duplicated my create and created a new group.  Within the group I merged the bottom of the crate into one geometry and then merged the top so that the crate has a top that can open.  I then created a simple layer so that I can change the color of the wireframe.
