Blending textures

Hi! I’m stuck with adding tree object to my program and i need your help :frowning:

My result and how it should look:

Link to tree .obj:

I tried this code but it doesn’t change anything (with GL_ONE it did but in a strange way):


Vertex shader:

#version 330 core
layout (location = 0) in vec3 position;
layout (location = 1) in vec3 normal;
layout (location = 2) in vec2 texCoords;

out vec2 TexCoords;

uniform mat4 model;
uniform mat4 view;
uniform mat4 projection;

void main()
    gl_Position = projection * view * model * vec4(position, 1.0f);
    TexCoords = texCoords;

Fragment shader:

#version 330 core

in vec2 TexCoords;

out vec4 color;

uniform sampler2D texture_diffuse1;

void main()
    color = vec4(texture(texture_diffuse1, TexCoords));


How do you load the texture for the leafs? Because it looks like it’s missing the alpha channel.
