No. This seems to be an offset table. You're supposed to search for an array of short intergers which are in an increasing order overall, as I descripted in this post:

2-8 floats (pale purple): it could be from 2 to 8 floats, didn't see more. it's a vertex modifiers as I call them. they could be related to the morphs or something else

Tosyk wrote:so, for example, in Model Researcher I can set vertex block start and vertex count to build vertex cloud in a few seconds, can I do the same in noesis to just understand the basic?

or you just search for a certain byte sequence which I don't really recommend unless there's no other way.

Bigchillghost wrote:It's just a piece of pseudo code in C to help you understand the structure of the vertex format. It's equivalent to the following pseudo code.

Why not use python with ModelResearcher (MR)? http://lazov.ru/mr/tutorial.php?name=tut_mr_scripts
