Hello!I'm writing an exporter to write c4d files from an application using melange. I'm missing the function MakeVariableTag to generate a Tnormal tag. My first thought was, that you could use MakeTag for all tags in melange. But the newly created tag doesn't allocate any normals. What is the right way in melange to generate a normals tag?
I'm using the newest melange sdk: Build #36137 - Nov 25 2010
Cheers
Frank

I haven't really looked into Melange yet, but most of the MakeVariableTag() variants were replaced by explicit new tag-types in the regular SDK... see if there's a NormalTag::Alloc() that you can use.

Two ways that should work:
BaseTag *bt = BaseTag::Alloc(Tnormal);
NormalTag *tag = (NormalTag * )bt;
OR
NormalTag *tag = NormalTag::Alloc();

Thanks for the infos. Unfortunately NormalTag doesn't have an Alloc function in melange, but after looking at the header (instead of only looking at the docs ;-) ), I found, that there is a Resize function:
_melange_::NormalTag* nTag = static_cast<_melange_::NormalTag*>(node->MakeTag(Tnormal));
if(nTag!=NULL) {
nTag->Resize(numPolys);
.....
}

Surely, you can use the Alloc() method found in the base classes that NormalTag is derived from? (BaseTag, BaseList2D, etc...)
