I have read all the relevant information, which was not much, and began to carry out tests but did not manage to obtain results.
I thought 3 images in TGA 32Bits, with an alpha chanel in photoshop, and I entered them in hmp, putting them in the following order...

SKIN0 Alpha 1 (tga,32bits) 512x512
SKIN1 textura ROJA (bmp,16bits) 128x128

SKIN2 Alpha 2 (tga,32bits) 512x512
SKIN3 textura AZUL (bmp,16bits) 128x128

SKIN4 Alpha 3 (tga,32bits) 512x512
SKIN5 textura VERDE (bmp,16bits) 128x128

With this test I wanted to understand a little about the workings of script, based on the information from "http://manual.conitec.net/amaterial2.htm",
it seems very simple but I had no luck. I have the correct version of 3DGS, and I believe the problem will be something daft, but I continue to do the tests without obtaining any result.

Some questions...

- how do you put the textures of MED in order?
- is a configuration in the MANAGE SKIN of the MED required?
- would anyone know where I can download a HMP prepared for this script, in order to see how it should be ordered?


Please do not refer me to the manual, because I have read it over and over again, thanks to everyone!
