This week I finished the first scene, added the blood decal effect to the scene and started building the second scene.
The principle of decals is to create a projection that projects the decal onto the object and adds bump, reflection and other effects.
I found some blood decals from the internet, created decal materials in Unreal Engine 4 and tested them. Here are the results.
I then placed the blood decal in the scene, but I found that the blood was not projected on the plants but directly on the ground, which was weird. After some research, I found that the reason for this was that I had used a plant brush to paint the plants, and they were not in the scene as a mesh. My solution was always. This gave my scene a lot more detail.
After completing the first scene, I started working on the second scene, which was a scene of two investigators searching the forest. With the experience from the first scene, the second scene went much more smoothly. There are a lot of resources, such as trees, rocks, terrain, etc., that are common. I also added some ferns to enrich the scene. I copied the lighting and fog from the first scene.
Nevertheless, I took some time to set up the scene so that the plants would look realistic; for example, the ferns would grow close to the big trees. I also placed the rocks according to a reference map I had found.
Next week I’ll be working on exporting animations from Maya to Unreal Engine 4, and I also need to export the scene that I’ve built to Ziying so he can do the animation. There are two more scenes I need to finish. Go for it!
