[SOLVED] How to fit decal to transformed mesh?

[ozRocker]

With this cat, if I add the decal then it works fine, but if I rotate the cat then add the decal it will not show.  How can I transform the decal so it would fit on the rotated cat?

In general, if I rotate and translate a mesh, what do I need to do to the decal position and normal to fit the rotated/translated mesh?  I'm using decals on specific areas, like on a person's heart or bellybutton and I want to be able to apply that decal anytime after the mesh has moved.

This seems to be a bug!

Actually after the rotation your point1 is no more valid (not on the mesh surface)

regarding your second question, you can just set decal.parent = mesh and it should work

so what can I do to make that decal fit on the rotated surface so it's in the same place on the cat when there is 0 rotation? Is there some kind of maths to apply to the position vector of the decal?

All good! I figured it out.

If I set the decal before any transformations and parent mesh to decal, then I can simply change my decal texture when I need to change decal.

Just to clarify, what I needed was a pattern on a person's t-shirt which can be changed to any image you want.  That image was a decal on top of the person.  I thought you had to remove the decal then create a new one in order to change the image but turns out you can keep the decal there and just change the diffuse texture.
