i get this error:‘if’ : syntax error syntax error on line 34
full shader:

float brightness = max(nDot1, 0.2);
vec3 diffuse = brightness * lightColour;

float dampedFactor = pow(specularFactor, shineDamper);
vec3 finalSpecular = dampedFactor * reflectivity * lightColour;
vec4 textureColour = texture(modelTexture,pass_textureCoordinates)
if (textureColour.a < 0.5) {
discard;
}
out_Color = vec4(diffuse, 1.0) * textureColour + vec4(finalSpecular, 1.0);
}
that if statement is used to make basic transparency i dont really know what i did wrong everything seems right to me
