I'd integrated Magic Particle to my engine but still have error about blending texture. The boundary of texture appears clearly. Can you help me to fix it

Try to save the external textures with the help of the editor. Use File->Save As (API).
External textures are created as ready textural atlases and ptc file contains right UV coordinates.
This variant more easy that variant with creating the atlases with the help of API.
