hi to all!
here's my problem:
i have many chunk materials sharing a single SHLChunk, each one with different
uniform parameters stored in SHLParameterChunks.
At some point, i need to swap the current shader programs in the SHLChunk with
others, with different code and the same parameters.
What i do is something like
beginEditCP( theSHLChunk, SHLChunk::VertexProgramFieldMask |
SHLChunk::FragmentProgramFieldMask );
theSHLChunk->setFragmentProgram( newFragmentProgramCode );
theSHLChunk->setVertexProgram( newVertexProgramCode );
endEditCP( theSHLChunk, SHLChunk::VertexProgramFieldMask |
SHLChunk::FragmentProgramFieldMask );
now, i'm expecting that evrything works correctly, but the result i get behaves
as if all uniform parameters was set to zero values...
in fact, if i rebuild all materials i can see the correct result, so i guess i'm
missing something crucial to get the parameters updated to their values as they
was before code-swapping. where i'm wrong?
thank you in advance
francesco
