Thanks Martin, thats what i suspected as well, but I havent done uvs in
almost 3 years so wasnt sure. I appreciate it. Will pass the info forward

   Hey guys,
 I'm passing forward a question from one of our new artists here that
 stumped me.

  Is there a quick way to check for inverted UV's in softimage.  3dsmax
 apparently has one built in.


  Basically sometimes the uv's get stitched together inverted and they
 are having a hard time detecting these.

Re: Test for Inverted UV's

[Martin]

Only one UV polyface in an island has been inverted/flipped ?

If that's the case you should be able to detect it in your Tex.Editor.

Softimage doesn't "merge" UV samples that aren't adjacent so their borders
should appear green/blue in the Text.Editor when you select them because
they are not "merged".

If the samples are adjacents and have the same coordinates, then they
shouldn't have green/blue borders.

Re: image plane?

[Martin]

I had an old script looping a folder's files so I added it to the previous
script I had sent.
Maybe it helps:

https://www.4shared.com/download/J4lYVJkg/mCreatePicGrid.js

What it does:
Open a ppg where you input your folder with pics.
Create an imageclip from every file in that folder
Creates a grid with the image clip name, applies a Lambert Material and
connects the imageclip to the material.
Resize the grid V size to match the image clip aspect ratio. It doesn't use
scale, but the primitive settings.
This for all the files in that folder.

What it doesn't do:
Basically doesn't check anything.
Doesn't check if he file is a valid picture or not.
Doesn't check if you already had those pictures or grids in your scene.
Doesn't freeze the TProjection.

Hope it helps.

And if you want to resize the object to match it's current image aspect
ratio you could do something like this:

//
//JScript
var sel = SIFilter(selection, siPolyMeshFilter)
for ( var i=0; i < sel.count; i++ ) {
var obj = sel(i)
var Mat = obj.Material
var Img = Mat.CurrentImageClip
var xres = Img.source.xres.value
var yres = Img.source.yres.value
obj.sclz = (yres / xres) * obj.sclx.value
}
//

It resizes Z Scale to match it's current image clip aspect ratio in all
selected polygon meshes.

Re: Test for Inverted UV's

[Enrique Caballero]

sorry guys, wrote that quickly

k so apparently these artists have somehow managed to create UVS where some
of the polygons in that UV island/shell/hull are facing in the opposite
direction.  So that on those polygons the bump and displacement maps are
inverted.

I'm not sure how they actually did this, they probably cut up the uv's and
then tried to put them back together, but somehow messed it up, and now
some of the UV's are flipped.

They are new starters from a company that used 3dsmax so they are still
getting used to the xsi workflow. They have asked us if there's a quick way
to tell if a UV is facing in the wrong direction. Apparently in 3dsmax the
uv's  would be a different color in the uv editor.

anyway i dont think that there is, as I've never ran into this issue
before, when I UV i just a combination of projections and uv unwrap. and
everything comes out okay

you should be able to use the existing beta install and just update the license

Yeah, in Fusion the ImagePlane3D is used to set up matte shots.
 You can feed it an image and it'll just give you a grid that's
exactly the correct size/aspect to match the image & it also uses
the alpha properly.  It's great for quickly setting up an
environment - you just load up trees, bushes, a treeline, etc.

I was thinking about it, and what would be really cool is if
there was a way for ICE to read a bunch of images, create an

Re: image plane?

[olivier jeannel]

I'm not working this week end (no Softimage), but I don't really get 
what is this image plane you're so enthousiast about.

Feel free to throw a screen grab (if you've got time).

Take care,

Olivier

Wow that's awesome!

Yeah, in Fusion the ImagePlane3D is used to set up matte shots.  You 
can feed it an image and it'll just give you a grid that's exactly the 
correct size/aspect to match the image & it also uses the alpha 
properly.  It's great for quickly setting up an environment - you just 
load up trees, bushes, a treeline, etc.


I was thinking about it, and what would be really cool is if there was 
a way for ICE to read a bunch of images, create an array and then 
apply them to the ICE rectangle particle shapes individually. 
 Basically the way you'd normally pick a group of objects for your 
instance shapes, but just with images.


Thanks!

If I haven't misunderstand what you need, you could do something
like this:

//---
//JScript

// Load Texture
var ImgFilePath = "Pictures\\TEST.tga";
var newImg = SICreateImageClip(ImgFilePath)(0);
xres = newImg.Source.xres.value;
yres = newImg.Source.yres.value;

// Create Grid
var r = ActiveSceneRoot;
var imgName =
ImgFilePath.substring(ImgFilePath.lastIndexOf("\\")+1,
ImgFilePath.lastIndexOf("."));
var grid = r.AddGeometry("grid", "MeshSurface", imgName);
grid.vlength = (yres / xres) * grid.ulength.value;

// Apply Material
ApplyShader("$XSI_DSPRESETS\\Shaders\\Material\\Lambert.Preset",
grid, null, "", siLetLocalMaterialsOverlap);
var Shader = grid.Material.shaders("Lambert");
SIConnectShaderToCnxPoint(newImg, Shader.diffuse, false);
var TP = CreateProjection(grid, siTxtPlanarXZ,
siTxtDefaultPlanarXZ, null, "Texture_Projection", null, null,
null)(1);
SetInstanceDataValue(null, Shader+".Image.tspace_id", TP);
grid.Material.name  = imgName + "_Mat";
//---

It will create a grid, keep the grid U value and change its Y
value to match the texture aspect ratio.

Make a loop with FSO and your folder with your textures and do
your 100 grids in seconds.

It's nothing more than a simple grid with an image mapped to
it.  But the nice thing is, there's no need to create UVs or
a material and the grid is automatically sized to match the
aspect ratio of the image you're feeding it.

I have a project where I need to create probably 100+ of
these simple image planes, so it'd be fantastic of Soft had
something like that.

Test for Inverted UV's

[Enrique Caballero]

Hey guys,
I'm passing forward a question from one of our new artists here that
stumped me.

Is there a quick way to check for inverted UV's in softimage.  3dsmax
apparently has one built in.


Basically sometimes the uv's get stitched together inverted and they are
having a hard time detecting these.

Thanks,

-Enrique

Re: Camera match to User View

[Vincent Ullmann]

Just to add something...
I just found, the place where User-Cameras (and Top/Left/...) live..

Set your Explorer to "Application" -> Views

Re: image plane?

My mistake, it was xres and yres.

And now that I have opened SI, I wrote something.

If I haven't misunderstand what you need, you could do something like this:

//---
//JScript

// Load Texture
var ImgFilePath = "Pictures\\TEST.tga";
var newImg = SICreateImageClip(ImgFilePath)(0);
xres = newImg.Source.xres.value;
yres = newImg.Source.yres.value;

// Create Grid
var r = ActiveSceneRoot;
var imgName = ImgFilePath.substring(ImgFilePath.lastIndexOf("\\")+1,
ImgFilePath.lastIndexOf("."));
var grid = r.AddGeometry("grid", "MeshSurface", imgName);
grid.vlength = (yres / xres) * grid.ulength.value;

// Apply Material
ApplyShader("$XSI_DSPRESETS\\Shaders\\Material\\Lambert.Preset", grid,
null, "", siLetLocalMaterialsOverlap);
var Shader = grid.Material.shaders("Lambert");
SIConnectShaderToCnxPoint(newImg, Shader.diffuse, false);
var TP = CreateProjection(grid, siTxtPlanarXZ, siTxtDefaultPlanarXZ, null,
"Texture_Projection", null, null, null)(1);
SetInstanceDataValue(null, Shader+".Image.tspace_id", TP);
grid.Material.name = imgName + "_Mat";
//---

It will create a grid, keep the grid U value and change its Y value to
match the texture aspect ratio.
