Hey guys!

I’m getting used to Away3D and am happy about the engine so far :).
Just now I was following one of the tutorials provided on this website: http://blog.tartiflop.com/2008/11/first-steps-in-away3d-part-3-texture-mapping/ .

One of the lines that I wanted to use was the following:
var tiledAway3DMaterial:TransformBitmapMaterial = new TransformBitmapMaterial(Cast.bitmap(away3DBitmap), {repeat:true, scaleX:.5, scaleY:.5});

But I run in to multiple problems: TransformBitmapMaterial can’t be found and Cast doesn’t exist.

I guess this is because I’m working with Away3D 4?
In that case are there any up to date tutorials any of you knows of?

Thanks in advance
Stefan

use this
yourMesh.geometry.scaleUV(5,5);

Thanks for the reply!

I’m very interested to know where did you find out? is there a tutorial or some place where it states what the changes are between Away 3 and 4?

For me it trows an error though:
Error #1063: Argument count mismatch on away3d.core.base::Geometry/scaleUV(). Expected 1, got 2.

So you can only scaleX and Y at the same time I guess… Next to that; Than how do you set the repeat?

1. i explore 4.0’s code. Because tutorial are rare…

2. the old version of 4.0 use 1 parameter. the new one from the svn uses 2 parameters.

3. to use the repeat use the material property. yourBitmapMaterial.repeat = true;

Indeed, in early alpha version, scaling uv’s was tiling along u and v axis using the same multiplier. You can now define a different multiplier for u and v.

Thanks guys!
This helps a lot already

Now I’m trying to position this bitmapMaterial nicely on my object but am having a hard time… can’t I just do something like:
myBitmapMatrial.x -= 50; ?

:D this away thing is fun!

In 3.6 you could do that through the TransformBitmapMaterial. change the offsetX or Y…

I’m a bit frustrated that there are no tutorials but I guess there is being worked hard by some people to get some tutorials available.

do you guys know of something like the offsetX anywhere?

i don`t think that is possible for now. the UVs are protected attribute of SubGeometry. UV editing usually done using 3D modeling software.  it`s much easier to do.

of course you can, simply access the subgeom.getUVData vector, change as you please and updateUVdata again. If you end up with values lower than 0 or exceeding 1, don’t forget set repeat to true.

For uv’s projection, you also can use Projector in tools package

ow it use getter . i did not notice that . so ..
myMesh.geometry.subGeometries[0].UVData;

and the Projector are awesome too. now I’m curious what away3D doesn’t have

Awesome! I’m gonna have some fun with that.

I found some helpfull functions here: http://markmail.org/message/jq6how5zz2vfgr76

Now another related question arises:
If I have a cube and I use a BitmapMaterial which I fit nicely on one face. Are the other faces filled with repeated border pixels? What happens to the other faces?
Is it possible to make a Bitmap that wraps around the cube automatically?

Thanks for al the help so far guys. Without you I had been stuck :D
