Texture shadow & rayshade

[Daniele C. <dca...@in...>]

In rayshade there is a problem when one or more texture are present.
The texture in shadow are completely black when a light are present .
I try to modify the code and it seems work fine.
I modify the function:

  void CImageTexture::Apply(
                 Geom                *prim,
         Ray                 * /*ray*/,
         Vector              *pos,
         Vector              *norm,
         Vector              *gnorm,
         Surface             *surf)

.. ... ...

switch (tComponent) {
                 case kImageTextureType_QD3D:
                         tmpsurf.diff.r = outval[rchan];
                         tmpsurf.diff.g = outval[gchan];
                         tmpsurf.diff.b = outval[bchan];
                         //my modify
                         tmpsurf.amb.r = outval[rchan];
                         tmpsurf.amb.g = outval[gchan];
                         tmpsurf.amb.b = outval[bchan];
                         // old code
                         /*
                         tmpsurf.amb.r = 0;
                         tmpsurf.amb.g = 0;
                         tmpsurf.amb.b = 0;
                         */
                         break;
