I've made some good progress lately, I am releasing a guide on proper porting from 7*5 to VX soon.

I did some tests, using same setting, h5 and reshade, in a test room with locked-in lights.

Then I created poses with camera keys to compare face. Having the luxury of both installed until I migrate everything over, I was able to do this fairly easily and will again for further trials.

This is a base model Miku, using Prylypala sliders.

Comparing OLD vs NEW/port :

To tell you the truth, I expected this to fail and made changes to the model, also gave new hair. This aside, it seems like the face is identical, only the eyes off-set did not come over.

It almost looks different, but it isn't. When you view the pics, flipping them back and forth on top of one another in a program, you can see the angles and the distances from key parts of the face are identical.

Why shouldn't they be? It's the same head. It's proof there is nothing weird happening with VX, I would say.

I assure, any minor difference is due to me making slight adjustments before this test (I shouldn't have, but again I expected much more difference, but there just isn't any, I saw right away.)

So, I would say this first port is complete. Besides me making changes, including body height (slight shift,) new hair and picking wrong eyebrow etc.

The important thing is the morphs work correct. I will do more testing to see how EMFS type models work, but I think any issues is more or less solved.

When porting, consider these:

-Lighting, very huge impact on how different a model can look.
-Cosmetic change, especially hair makes a big difference.
-Level def, more light sources and things, as well as perspective in-game.
-The exact .tri file you used in whatever headmod replacer or EMFS.

I will write a detailed guide soon for every type of model port. For now I am content, on a OCD level, that base model transfers flawlessly.

If you want to do the test yourself on a model you are trying to port and have both version installed, here is the items I used:

CameraFacePoses.rar FaceTesterRoom248.rar HookAndReShade.rar

In conclusion, with the old sliders back in version p, model porting should be more or less perfect, it's all the little stuff like eyebrows that will be an annoyance at best.
All there is to do is fix the eye-offset, but there may actually be an easy solution that I'm overlooking to that too, just dont know what yet.

Here I will share this model, my first successful port, it is my remake of an old model posted on MG:
