Hi,







#declare MyTexture = texture{ pigment {agate} }

#declare MyOtherTexture = texture{  MyTexture pigment{ granite} }



are legal, but



#declare MyTexture = texture{ uv_mapping pigment {agate} }

#declare MyOtherTexture = texture{  MyTexture pigment{ granite} }



cause a parser error on the second declaration: no matching } in 'texture', 
pigment found instead.



Is this a bug or there is some reason for things work this way?



I also found recently that POVRAY crashes on my system when using the old 
tiles texture without specifying one (or both) textures of the list, e.g.



sphere{0.0, 1.0 texture{tiles {tile2}} }



results in a message box:

The POV-Ray core rendering threw an unhandled exception.

The backend thread has been shut down and will not be able to perform any 
further renders.





Could someone please confirm it?







Thanks in advance,



Hugo.
