Game – Dumpster
Here’s the completed low poly model of the dumpster, accompanied with a few bin bag buddies. All objects were baked from a higher poly version.
The dumpster contain 2310 tris. I decided not to go overboard with the dirt and grime overall and kept it to a minimum; having only heavier dirt where it would be required like the inside of the dumpster, this gave a general use appearance to the model.
On the bottom surface of the dumpster, I’ve added some piles of scraps and rubbish, this was done with the aid of Crazybump to generate the normal and occlusion map to add some subtle depth to it.
The high poly models of the bin bags started out from a normal sphere that has been altered using the FFD 3x3x3 tool and the Noise modifier to give some randomness to the shape. Then in edit poly I used the paint deformation to brush in the creases to give that authentic material look.
After I was satisfied with the models; I imported them into Polygon Cruncher which optimizes the high poly down to create the low poly version. After a few tweaking of the edges it was ready to be baked.
The low poly model of the small bag contain 282 tris and the larger one has 242 tris. To add some variety to the models, I’ve created two versions for each, one white plastic bag and one typical bin liner bag.
I knew before texturing that the plastic see-through bag would add more realism and interest to the overall piece and was worth the extra texturing work involved. As it was a spherical shape I thought it would be difficult to texture the pieces of rubbish together without showing large visible seams, but the randomness of the texture help hide most of it. I tried not to spend too much time on getting it perfectly seamless since it’ll be shown quite faint from the plastic material.
Crazybump was used again to generate a normal map from the scrap image to add presence to the rubbish and tin cans, this was blended in subtly with the crease normal layer to create the final look.
