Hey @imarabinda
Sure thing I can show you how to show normal maps, etc using the Inspector.
Before we dive-in, in the future, please provide a playground with your question. That is the easiest way for people to help you learn. It’s also an expectation around here. 
Let’s start with this one:
With the scene loaded, find this button at the top:
That opens up the Inspector.
Next, in the inspector, expand Materials and select “YetiMat.” This selects the Yeti’s Material.
Next, if you scroll down in the general properties:
You’ll come to the “Channels” section.
If you select the little wrench icon on the far left of Bump, it will show you the Normal Map.
You can toggle “isolation” for any of the texture channels through the wrench icons next to each item.
The inspector is definitely your friend!
I hope this helps!

https://playground.babylonjs.com/#S0KJUA#39 , this is my play ground, but i see there is no bump texture available as you’ve shown in the yeti image
Correct, it looks like you have the model, but no textures for it:
You would need to get the source textures and then apply them either in a DCC tool like Blender, or directly in Babylon.
If you go the Babylon route, there are 2 options, applying them directly via code, or using the Node Material Editor.
If you’re new to 3D, then I’d suggest taking a look at the Node Material Editor. It’s a code-free way to set up materials for your scene.
Honestly, I wouldn’t start there (sry 
). NME might be code free but it requires knowledge on how to create materials at a very minimum. I think the easiest way would be to first learn how to do it with code, using standard, metallic and PBR materials. All nicely explained in the doc and I would start from here.
Of course, my opinion only…and meanwhile, have a great day

Honestly I would go even further and suggest anyone who is completely new to 3D to start here: Introduction to Babylon.js Features | Babylon.js Documentation (babylonjs.com), as I think jumping directly into materials without having knowledge of things like camera, vectors, etc, can cause a lot of confusion 
@PirateJC could you please tweak this material to normal map type https://nme.babylonjs.com/#AZM7DN#2
Hey @imarabinda,
I’m not sure I understand what you’re asking for.
There is no “normal map” type for the node material editor.
The normal map is usually a texture file generated in a DCC tool like Blender.
Displaying that texture in the Node Material editor is incredibly easy.
You really only need 2 additional nodes beyond what the default NME template has:
A MeshUV node and a texture node.
Then you simply load your normal map into the texture node and hook everything up like this:
