How to combine 2 normal maps?

Hi!I’d like to know:

I have a tiling brick texture,with of course a normal map of it.

I also have a normal map from my high poly mesh baking

How can I combine them together with the node system?Would love to have a picture if possible :slight_smile:

Thanks a lot!

Hi!

This is a docs about the various method of blend normal maps:

Thank you! This is exactly what i was looking for!

The BlendAngleCorrectedNormals node is great to add a detail/surface detail normal map to an existing normal map, but just adds one map to the other.
Sometimes you want to use an alpha mask to use more subtle blending. Adding an extra step with the FlattenNormal node before the BlendAngleCorrectedNormals seems to work nicely…
