there is no nice way, but you can do something like this. For the first
render frame walk through all materials und call activate and deactivate
on each TextureChunk.
(newbie alert)
i tried to use the traversal function to do this, but i see no
change (only wild tumbling solves the problem):
...
traverse(scene, osgTypedFunctionFunctor1CPtrRef<Action::ResultE,
NodePtr>(wakeupTextures));
...
and
Action::ResultE wakeupTextures(NodePtr& node)
{
if(node->getCore()->getType().isDerivedFrom(Geometry::getClassType()))
{
MaterialPtr matPtr =
GeometryPtr::dcast(node->getCore())->getMaterial();
ChunkMaterialPtr chunkMatPtr =
ChunkMaterialPtr::dcast(matPtr);
if ((chunkMatPtr != NullFC) &&
(!chunkMatPtr->getChunks().empty())) {
StateChunkPtr chunkPtr = chunkMatPtr->getChunks(0);
TextureChunkPtr::dcast(chunkPtr)->deactivate(renderAction);
TextureChunkPtr::dcast(chunkPtr)->activate(renderAction);
}
}
return Action::Continue;
}
is this the way to do it? ;-)
