Add BMP, ACT and SPR to a Skill?

[Kyunhee]

This has burned us with my brother, we have made a skill called SM_VANGUARD, it was only for the concept of creating a skill to know how it worked, the point is that the skill works but the image it shows is that of am_berserkpitcher

We have inserted the files corresponding to the skill in the folders
data/sprite/¾ÆÀÌÅÛ
Here we have put the Act and Spr

and in data/texture/À¯ÀúÀÎÅÍÆäÀ̽º/item
We have put the BMP

The error is always the same, we have made these changes both in the data.grf and in the Rathena.grf, I have also created the same routes in the folder where the client is and gives the same error, even with everything simultaneously gives the error, something is missing? What are we doing wrong?

The worst thing is that the skill works, we can level up and even fulfills its function, but the first time you open the skill tree the error is the same

PLEASE HELP

I have solved it. I do not delete the post in case someone else solves the doubt

when saving the bmp put IMAGE>MODE>INDEX so the data.grf (Photoshop) will read it
