Blender Unwrapping Issues

[Chihuahua]

Hello, I have just started with blender and could use some pointers on unwrapping this wall piece I made today. I am using blender 2.63 (The latest recommended release)





Please tell me if you need more information, like the wireframes/etc and I will try to provide it to you.

If each square is going to be the same thing, unwrap the squares sticking out separately with the 4 faces on each side attached then stack them on top of each other for the most UV space possible. It all depends on how you're going to texture it really. For the lightmaps you could just do a planar projection and smooth it out as one solid piece.

i show a little uvw mapping in my blender videos might be an idea to have a watch

Alright, I've watched a few of the UV map videos and while they have helped immensely with basic setup and understanding, I'm still unsure of what to do. I have, however, done a lightmap project and arranged all the faces as they would be on a completely disassembled mesh. It's very ugly, but hopefully it can help you help me with how to arrange it like Jessie G stated.



The final mesh would hopefully be plastic, seamless plates with possibly metal trim on the bottom. so stacking all the plates into one would be very viable. Lightmapping via planar projection I'm unsure of how to do, and it is not listed in blenders unwrap menu.

ok if you can "stack" the uv's for the first channel thats great, but for the second uv channel (lightmap) all faces must have unique uv's, you can achieve this by removing the "seams" that you created for the first channel, i know i didn't show this in my videos this link might help you understand the why's but not the "how to"

Alright, Using orthographic and project to view I was able to create these UVs. Are they good enough for UDK?


Channel 1 (Diffuse/Texture Coordinates)





Channel 2 (Lightmapping Coordinates)





And here is the result in blender's viewport

should work fine
