Question about swimming textures

[sandra7]

This fits both Character rigging, Rendering and animation. So I felt it would fit better here. I have a character that was boned, ik'd, UV mapped and materialed. The textures seem to swim. So I used a tecture reference object, did not work. I created a file texture (baked it), didn't work. I knew it had to do with the order of the dependancy graph. I made sure I checked apply before deformers was on, but they were after deformers. So I tried to move them in the dependancy graph. You can't move the UV's in the dependancy graph. I fixed it by transfering the uv's to another mesh which then put the uv's before the deformer.

My question is.....1. Why can I not move UV's in the dependancy graph, 2. why did my mapping not go before the deformers when I made sure it was checked, 3. why did the reference object and the bakeing not work? Also...Was this solution the best solution here?

thanks

What type of surface is this Poly or Sub-D?

[sandra7]

Poly. Why would sub-d be different, especially with a poly proxy object?

[gmask]

I'm not sure that it would make a difference but I wanted to know anyway..

According to the dcos
file:///C:/AW/Maya4.0/docs/en_US/html/UserGuide/Rendering/Texturing3.html#207844
You have to make the reference file before you animate the object

I cannot imagine why the convert solid texture function did not work for you either?

So when you say it appears to be swimming.. is this severe of is is it minor even if you translate the surfac ein question? Is this every surface of the character or just one surface?

[sandra7]

It is on the face and the texture stays when the head and jaw moves.

And convert file texture did not work either.
Shouldn't you be able to move any of this in the Dependancy graph?

[gmask]

Uh.. I don't really think the dependancy grpah is going to help your with this..

It sounds like you used some sort of projection to texture the face and unlike the deformations you cannot tell Maya to texture first then deform texturing allways goes on top.. that is what texture reference objects and convert solid textures is for.

Make sure that the new shader that is created by convert solid texture is assigned to the face. At this point reference objects won't help you unless you unbind the face then make a reference and then rebind the original face shape.

.. OK I played around a little bit with some bound polys and if you created a UV planar projection for the face then the texture should stick even with deformations but if your texture is using a projection map then it is not going to stick during deformation.

A few notes (dont know about maya 4.5 tough), texture referencing doesnt work on subds... it works fine on polys and nurbs tough.

And as gmask pointed out make sure your texture reference object is proper... ie make sure its compleetely animation free. Or use uv mapping... which should work fine since you use polys.

And one thing... referencing wont work if your uv maps overlap eachother, since it works on uvs. so you cant just referece and forget about uvs.

[sandra7]

The uv's were set up properly. That's why the reference object and convert file texture should have worked, but didn't.

My question still remains....WHY does it not work???
I have fixed it. I wanted to know WHY the normal methods did not work. And why my uv's did not set up before the deformers when I had checked it?

[joojaa]

Make sure the uvs are in base uv set not in naything else! Oh and i think the uvs have to be in 0 to 1 space too...
