These textures are H.E.V. Charger and Health Charger from the Black Mesa game released in 2020.
I spent a lot of effort preparing these textures and sounds. These textures are 99% like original. Textures will look similar to 3D wherever you look at them. The reason for this is that the light and shadow are proportional in the texture.
You must have a Wad viewer to upload these textures to the Wad file. Those who use detail textures can directly copy the textures and transfer them to the "detail" folder. This textures mod replicates the original half life wad. Don't forget to copy a save before changing it.
