Changing mapping modes (spherical, cyclindrical, parametric, etc.)

Is there a way within DAZ Studio to change the mapping modes used by a shader (that is not already built into that shader, and without remapping the object in a 3rd party application)?

for example if I have a shader with a pattern or tiled to be a pattern that is in rows and columns, and I wish to apply it to round object like the ring in the screenshot, it would be nice to apply it in a spherical or cylindrical mode so it had a round pattern similar to the sphere in this screenshot rather than just a rectangular pattern that does not line up with the shape in question.    I'm wondering if there is a way to choose amongst several common basic ones rather than using the default of the object.

I've also attached a Bryce screenshot showing the types of options there in case that helps illustrate what I'm trying to say.

    No, not as a rule - the standard shaders are all UV mapped so you would need to chnage the UV mapping (in an external application), then load that as a new UV set. If you have a custom procedural material that uses some form of 3D projection then of course that code (or those bricks) could be changed, but it's soemthing that the original developer or soemone with access to the code/brick network would have to do, not a simple switch.

    What happens if you export to Bryce, change the Texture mapping mode to suit & then export out of Bryce & re-import  back into DAZ?

    Chohole can correct me if I am wrong, but as I recall the projection modes used in bryce do not use or affect the UVs (unless you use UV mode) so the exported OBJ would still have its original mapping, or none.

    Although it's been years since I've used it and I'm going to have to go relearn (hopefully I wrote something down), I assume I could just use UVMapper.  I just wanted to make sure I wasn't spending a lot of time doing something I didn't need to do if there was already a built-in option to do it.
