How To Get Rid Of Swimming Textures?

[craig88]

I have followed the tutorial for the crackerbox (Lesson 1 UV texture mapping in the Maya tutorials) and at the end of the tutorial tried to animate the box to rotate . The texture then moves over the surface. I tried texturing -> create texture reference object, but that didn't seem to help. The troubleshooting section says "Move the original 3D texture node from the original object's hierarchy into the referenced object's hierarchy. " But just how is that done?

most likely the issue is that the texture projection is not being rotated along with the geometry. just parent the projection node (which you can easily find in the outliner) to the geometry and you should be good to go.
you really shouldn't need to reference anything just to rotate the box.

Texture referencing does not apply to uv mapping! It applies to texture projection mapping. (which is different, than projecting a uvmap, the other works on the surface underworld and the other on the shading process).

Think about your history the uv mapping operation should be put before the transformation in history chain.

I didn't use a projection, it was "normal" uv mapping using the "create uvs" -> "automatic mapping". The Outliner only shows my crackerbox, no other objects that i can find. Also if i redo the tutorial and texture the box with the builtin "checker pattern" I can rotate it and the texture won't swim. Seems to have something to do with the UV mapping.

OK i'm looking in the hypergraph, is see the shape node and the transform node for the box. The shape node looks some thing like this: polyCube1->polyAutoProj1->polyMapSewMove1->polyMapSewMove2->polyMapSewMove3->polyMapSewMove4->polyTweakUV1->cracker_box->lambert2SQ

the transform node is currently not connected to the shapnode. The transform node is only connected to a cracker_box_rotateY node. Am I supposed to connect or parent the transform and shape nodes in some way?

delete history. if you must change the pcube then it gets tricky as youd need 2 cubes.

OK that fixed it! Here is a summary for the newbie FAQ section:

PROBLEM: Textures swim when animating an object after using UV texture editor to position texture.
SOLUTION: After texture is positioned as wanted, delete construction history!
Select the object, Select Edit > Delete by Type > History

Dont draw that conclusion, it just happens to work here since your not actually doing anything that needs the history for anything, you cant go deleting the history if your actually using it as a building block. Wich is the case most times.

Just your not using the history for anything so yu dont need it.
