Hi all.

In this tutorial i'll tell you how to port models from cataclysm 4.03a to wrath of the lich king 3.35
Let's start.
What we need:

• 010 editor
• 010 templates (m2)
• Time

Open our *.m2 file in 010 editor. We could see this. It`s hex code of m2 file.


Now open m2 template


We have smth like this


Now, change version from 272 to 264
(10 01 00 00 to 08 01 00 00)
Go to the "nTexUnit" section. Change 0 to 1
In "ofsTexUnit" section copy Value from "ofsTransLookup" for example.

Now we should edit camera. When we load m2 template on model which have version 10 we got error.
Lets fix it.
Change the all -camera values to , and then try to reload template

Little addition to tutorial :

If you have problems with (dynamic) shadows "moving" and following your character's movement, that trick seems to fix it :

- Open the Cata/mop skin file associated with the model in 010 Editor.
- Apply the skin template.
- Go to submeshes (each of them).
- Change "unknown" field 0x10 (between startbones and rootbone) from 0 to 1.

I have no idea why, but it works xD

This attachment is the same but as rtf document.

I've just found, that this tutorial breaks models while doing the camera fix.

There has been some change in the structure of models with cataclysm. one of them has been fov now being animatable.

In order to fix this, copy the data behind ofsCameras to the end. You should copy quite some bytes as you need to make sure, you're copying all of it.
After copying the data to the end of the file, adjust ofsCameras in the header to the offset where you just inserted your copy.

Now, apply the template again and navigate to the first camera. go to fov. now, INSERT 4 bytes at that place and change the value of fov to 0.7 if the camera is a portrait camera or  0.97 if its the charselect one. (you may want to try around with these values a bit later, if the outcome is not perfect).
Reapply the template.

If there is more than one camera, now go to the next camera. It will show up bad values in the template and most likely will have caused an error once again. Go to the beginning of the camera and DELETE 20 bytes there. The data in the template should now look "normal" again. Repeat what you just have done for the fov.

Repeat this for all cameras in the file.

It should now work with 3.*.

Schu. I honestly have no idea what version you're doing this one or what you just said, Picutres and/or Laymans terms of 'Behind' Cameras. Do you mean copy before and up from the start of them or after and down?
