Without any changes in Blender, you have to export your model with a scale of 100x to get the same result inside Unreal Engine 4. The first thing to learn is, that both programms have different units / scales. UE4 can import 3D Objects with the FXB format and Epic Games was involved in the development of the newest fbx exporter inside Blender. Now we are getting closer to actually using our models withing the Game Engine *cheer*.
(UDK infos are still valid for UE4) FBX Exporter and Import meshes into UE4 To understand the problems and why something happens, these lightmapping basics are a lifesaver:ġ8 Important Principles for Creating/Using Lightmaps Even with these simple meshes I had quirky outcomes with the automatic lightmap creator in UE4. You can have UE4 create the Lightmap on its own while importing the mesh but each source I read recommends to build your own on a second UV Map channel. The Unreal Engine needs it to bake lightning information onto the model. The Lightmap is technically a second UV Map. As for my basic models I was able to use the built-in unwrap tool to place everything.Ī big help was this blog post about Basic UV Mapping in Blender. There are a lot of tutorials about this topic on the web, because the better your unwrapping is, the better your model will look in the end. The process of creating the 2D surface map is called “UV unwrapping”. To place materials, colors, textures onto a 3D model, you have to build a UV map. UV mapping is the 3D modeling process of making a 2D image representation of a 3D model’s surface. Better be slow with proper understanding and memorizing the steps for future usage! UV map and UV unwrapping You get a step by step example with all the Blender keys and commands needed. To build my first tree out of an icosphere and a cylinder I used the wonderful Secrets to Creating Low Poly Illustrations in Blender tutorial. My first steps took ages with a lot of head scratching.
So my choice for now is Blender, which is completely free to use!īlender doesn’t make it easy to start with. But the licenses are rather expensive and nothing to “play around with”. The big players on the market are software suits like 3D Max, Maya and ZBrush. While you can use your Gaming Engine to block out your levels with brushes or simple pre-made geometric objects, you really have to look into a 3D software to build your own objects (meshes). I am going to break it down and link to the resources which got me started.
Blueprints to build new objects out of different static meshes to have some variation.To get my first basic scene in UE4 with self-made static meshes, I had to learn more about these topics: So what’s the ‘pipeline’ I was writing about? This scene has only two different meshes.
