Vehicle with windows

[SledgeNE]

Hello together! :-)

I am new with the UDK and i hope you can help me with this little question. I want to import a vehicle that has windows. How can i do this that the UDK shows the windows transparent? Sorry for my english. ;-)

(What i am using: Blender 2.65, UDK 10-2012, Gimp 2)

you would need to apply 2 materials in blender (you might need 2 textures and UV's as well depending on how you do it) and then for the windows in UDK change the material setting to "translucent".

@ smokey13

Thanks for your answer. My first idea was to take the texture and create in gimp a alpha texture for that i have two different things. I would delete the windows from the texture and in the alpha the windows are contained. It's very confusing. :-)

Edit: I think i am beginnig to understand. I must set Vertex Groups for the parts and in the UDK i can change it to translucent.

In maya I simply assign a different material to the geometry of the window, import the mesh to UDK, edit the translucency of the material in UDK, bam done.

vertex groups are used to assign vertices to bones.

I must watch you tutorial with your buggy. It's confusing. :-)

@ Henrik
I must create a extra material in gimp for windows?

I am very confused because, i understand that a vehicle must be one mesh. With one mesh i can only set one material. That's seems my problem. :-)

No, you can assign different materials to certain parts of your mesh in blender.

Gimp does textures, not materials. And yes, you probably want to have a separte texture just for the windows, or at least for their opacity.

Thanks! Now i've got it! :-)

A very little question: What is the problem, when i import my mesh and the mesh has no blue-white tiles?

you would need to apply 2 materials in blender (you might need 2 textures and UV's as well depending on how you do it) and then for the windows in UDK change the material setting to "translucent".

So are you using a regular material for the vehicle? I've been using Material Instance constant materials for vehicles cause that's how I was taught to do it for vehicles. So with that said, how would you switch a MI material constant to translucent?

what does it have instead of the blue and white material?

well I use "material instance constant" and "material instance time varying" because I use the UT code but you can use normal materials as well. I don't think you can make MI's translucent but i'm not very good with materials so I could be wrong.

@smokey13

A blank texture. I put some Screenshots from my progress of modeling, so you can see i effort me to learn. When i make a mistake, please say that. ;-)

In a Youtube-Video you can see that someone put the Material for the windows of his car in UDK.

[smokey13]

what do you mean by a blank texture, if its just dark grey its a UV or material issue.

to your lambo, your diffuse texture is 640x400, it needs to be a power of 2 (64,128,256,1024,2048,4096). because you are using a basic texture you can overlap more of your UV islands. also you don't need a lightmap UV for skeletal meshes.

there is more then one way of making a vehicle with windows, I did the windows of my example almost the same way as the guy in the video but used a basic texture for the diffuse in the material.

nice model

Thanks, but without the great Tutorial from Peter Drakulic from youtube i would never be so far. I will see how long i need when the Lamb is driving in the UDK. :-)

Edit: Just a little Update. I had setting up the bones, but they are not parented so far. Here is a new Screenshot from my progress.

So, i forgot to take a bone for the socket. I must create Vertex Groups, too. There's a lot to do. But it makes fun. What do you think? I've got it, or not? ;-) About the damages from the wheels: Must i do take the vertices from the wheels within the vertex group from the damage-bone on every side?

Edit2: You can take a look on my Youtube-Channel. It's nothing special there, but some Blender-to-UDK-Videos, more or less. :-) https://www.youtube.com/user/SledgeNE/videos?view=0
Well, i found a little tutorial about windows and creating glasses in GIMP: http://usingudk.blogspot.de/2011/07/...texturing.html
