Rendering Normal maps in Turtle

If you try to render a normal map in Turtle for Maya , you will notice that the result image will render as bump calculation.

 

This is due to the fact that the bump2d node in Turtle is implemented to be an exact match of Maya’s bump2d, so it doesn’t support normal maps be default.

Instead one should use the ilrNormalMap node, by connecting the image directly to that node then  the ‘normalCamera’ attribute on the Shader.

 

Now the render should be fine.
