Turn off Gamma Warning

[dj_buckley]

How can we turn off the annoying normal map gamma warning.  It makes me want to throw my PC out the window.

This.

Also "Ignore similar messages", if that doesn't help, to get rid of them, at least for that instance of 3ds Max.

My normal maps are setup correctly.  So I don't fancy using that button in the converter.  I'll give ignore similar messages a go.  Hopefully it's global and I don't have to set it every time I run max.

It's because of the setup in the screenshot.

If I bypass the mapping randomzier the error goes away, but ALL my materials are setup like this

Your normal map is wired incorrectly. You should plug Corona normal between bitmap and randomizer, not between randomizer and material. Don't know if that would help with false warning messages, but your way of connecting will give you wrong normals whenever rotation is randomized.

Thanks Rom, although I don't randomize the rotation after having an issue way back with a leather material I was working on.

Good to know though, as I always thought it was Bitmap then Randomiser because it's the bitmap I'm randomising

I just checked this to be sure - rotating a texture is not quite rotating a normal map, as the axis/rotation interpretation for normal map is different/more complex than simply rotating a texture.

You can still get correct results with normal map after randomizer - you may just need to flip different axes to achieve it, which may not be quite straightforward.
So it is best to let randomizer know that a specific map is a normal map and its rotations are to be treated so.

Another quick question about this Rom, what about when mixing normals, should it be like this

Looks about right, but don't just trust me, better run quick test and see if there's any issues. I personally never used a setup like that, so i don't know if there's some catch :]
