Normal values are not being passed in shader

[kashyappiyush1998]

Hello everyone,
I am using Sofa scene file to load obj files and draw them. Before running the draw function I am activating my shader.

myShader.use()
sofa::simulation::getSimulation()->draw(vparams, groot.get());

Then inside my vertex shader, I am taking position, normal as input

#version 330 core

layout (location = 0) in vec3 pos;
layout (location = 1) in vec3 normal;

The object is being drawn showing that position values are correctly taken as input. However when it comes to normal...
Then I visualized those normals. Below is an image

I checked inside Sofa's Meshobjloader.cpp file in function MeshOBJLoader::readOBJ. Normal values are printing correctly.

What could be the issue??
Any help is welcomed.
Thank You

Hi @kashyappiyush1998

In your code, how do you connect the normal data from the OBJLoader to the one in your shader code?
However I never worked myself with shader.
