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

My result and how it should look: www.imgur.com/a/r5VtC

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



glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glBlendEquation(GL_FUNC_ADD);

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.
