Normal map material issue.
Hello, I have a question if someone knows the answer. I am struggling to create a correct normal map in a V-Ray material.
What I do is: a) I create a V-Ray node material, b) I drag n drop a normal map file, c) I connect the output from the normal map file to the bump map input on my material and d) I change the bump type to Tangent Space.
When I render the bump is very weird. Please someone help.

Hello,
In V-Ray in order for the normal maps to work properly, you need to do these two things.
1) When you load the normal map into the node editor, you will need to change the “Transfer Function” to “Linear” (check 1.jpg)
2) Now, Press the “+” on the node editor and from the color add a “Normal Map” node. (check 2.jpg)
3) Lastly, you will have to connect the output from the bitmap to the map from the normal map and the output from the normal map to the bump map of the material. In the “Normal Map” node change the Map Type to “Normal Map in Tangent Space” and now it should render correctly. You can see in the Material preview how the material looks like. Please note that in order to increase or decrease the bump effect you will have to adjust the multiplier. Nothing else. (check 3.jpg)
Hope this solves your issue.

Wow, this fixed my issue. I was so annoyed by this… The bumb is now rendered correctly, but now I want to make the effect to look denser. What shall I change? Thanks again.

Hello again,
I am happy that worked for you. If I understand “denser” correctly,
1) Have you UV unwrapped your model?
2) If you can’t or don’t know how to do that, you can change the projection to “Cubic” and decrease the Length U & V to your liking. You might need to try multiple values to get your desired result.
3) Alternatively you can go into “Texture Mode” with Cubic Projection and scale down the material preview to your liking. It will have a similar effect with the 2nd method.
If your model is too roundy, you can try other projection modes. The perfect way will be to create a UVW Map.
I hope that helped.

Cubic and 60% on both did the trick. Thank you very much for your fast response.
