repeating textures

[fabs79]

Hi, I have another texturing question: I understand that I need to bake a texture in Blender if I want to export it into a collada file so I can load it into MCX, I successfully did so with a few models. But what if I want to use a repeating texture? Let´s say I create a fence 1 metre high but 100 metres long. In Blender I can apply a 1024x1024 pixel texture to the fence and have it being repeated 100 times in the y but only 1 time in the x direction. Within Blender this looks fine:

But when I want to export this object, I need to bake the texture to a blank 1024x1024 image, it looks like this in MCX:

It seems the texture is no longer repeated but stretched across the whole length of the fence. Is there any way to fix this? I wanted to attach the blender file, but the uploader doesn´t seem to allow for .blend extensions

Thanks and best regards,

Fabian

Why do you need to bake the texture? Just keep it tiled. That should work. Just keep in mind that the 100x repetition must be done in the UV map itself, not via the mapping section of the texture panel.
Also if you like to attach the .blend file just put it into a zip and you're fine.

Whenever I try to use a texture without baking it doesn´t show up in the converted collada file I load into MCX. I was told that all the textures need to be baked before exporting on this forum. Could you show me how to do the repetition within the UV map? I´m pretty new to Blender and never worked with UV maps before, I understand how they work in general, but don´t really know which special considerations I have to take into account while texturing (I only used an old Sketchup version before where texturing was done directly on the faces of the model and where could just adjust the size of the texture accordingly). I´m uploading the blender file for you to check it out. Thanks for your help!

I just had a look at the .blend file, sadly the original fence texture isn't included.

First of all:
For exporting I can't recommend using cycles. Use Blender Render instead.

Getting a repeating texture via UV is as simple: just drag the UV vertices beyond the texture sheet and the texture repeats. I your case the best is selecting everything and scaling it 100x along the according axis.

By the way you would do yourself a favor by not modeling the fence as a scaled cube but just add a solidify modifier to a vertical plane defining the thickness.
That way you will only have one face to be mapped and there is not really a point in mapping a 2cm thick rim face anyway.

Dave, thank you a thousand times, I finally understood how the whole UV mapping actually works, you probably saved me countless hours for texturing in the future. I actually created the fence using a solidify modifier, but I didn´t know that you could unwrap and texture it before actually applying the modifier. Thanks for that, too. I see I still got lots of things to learn
