Hi people,

Is there any way to use a regular mapping projection while using UV
mapping on an object?
That is, once you've declared that an object uses UV_mapping, how would
i then include a map or texture as a planar projection (not using the
uv_mapping), for example?
Would it make more sense to be able to declare uv_mapping at the
individual texture level? It would ceratinly be more congruent with
other apps concepts of mapping.
It's just that i've needed to combine uv_mapping and various projections
on the same object.

Is this old news?

regards

Working on deform patch I have noticed the same problem
I wanted implement leyered textures from before and after deform
but I have noticed that some object's modifiers are privillaged.
UV_mapping in my opinion should be on/off to support pairs object-texture
just like rotate after texture rotates both - object with texture.

Originally, I tried to implement uv mapping as a property of the texture,
but I ran into some major technical difficulties.  That is why it is a
property of the object.  I am attempting to improve it for POV 3.5 so that
it works on a per-texture basis, but there are no guarantees.

yes, I know, no comments about 3.5, but can you describe a little what's the
problem ?
