When using standard normal maps, an error occurs. To fix this error, you need to save normal maps with an alpha channel (in order to get a normal maps in RGBA format). And I don't know how to make this alpha channel.

Oh, sorry then I have no clue how to do that either

It's going to be drawing-tool specific, but look for some menu or dialog that mentions "channels" and typically there will be an option to add an alpha channel there.

So its been some time since I made a planet, but I am trying to make a titan analogue (Tekto is nice, but not what I'm looking for), and I'm having the same problem.

I don't remember what I did last time.

Can anyone tell me what needs to be done to generate a proper normal map from a heightmap?

This video covers Planet Creation well.
