Blender Cookie has 2 tutorials that can be very useful for UT 3/UDK mappers. They cover many techniques including baking high poly meshes to low poly meshes, creating diffuse textures in Blender as well as others.
I have followed and replicate the Sci0Fi pan tutorial with good results.
Part 1 covers creating the model in blender, then creating a UV map.
Part 2 covers taking the UV texture that was created in part 1 and importing it into Photoshop. Once there, sample textures are used to create the diffuse/specular/bump maps. The tutorial also shows how to continue creating the texture while in Blender. It also covers creating materials that can be used only in Blender and how to setup the model to render.
I like the second tutorial as it was interesting how to create a texture from source photos and how you can alter your texture in Blender as well.
This is a great tutorial for those who are still learning the basics of Blender and those who want to get a better idea of the workflow.
3D Buzz has released their first group of video tutorials available for everyone. They cover the basic layout of Blender. You can download them individually (.RAR file that contains a MP4 video).
MCampagnini created a little explanation about smoothing groups and how they are calculated in his exporter.
The other day I was trying a few things and came up with these simple, but effect “techniques”.
Here is a picture of a simple floor tile mesh. I created 1 square [64×64 units], then UV mapped it. I then duplicated them over and over again until I had a 1024×1024 floor mesh. The material shown is from a stock UT package, [Material’LT_Floors.BSP.Materials.M_LT_Floors_BSP_Organic05b_TileBreak_NoBump’].
Using the same 1024×1024 mesh and following this tutorial from Blender Nerd, I was able to create a simple normal map from a mesh. This can be combined with a simple base stone/concrete texture/material in the editor for a custom material.
I was browsing the Epic/UDK forms and fond out that MCampagnini updated Rich is Bored’s ASE script to offer better support with Blender 2.57 and the UDK/UT 3 editor. I tested out most of the known features and have updated my Blender To Unreal page. If you are an Epic forum member, please drop by and say a thank you or you can visit his site where he explains the updated script.
