IN PROGRESS: Invert Normal Y in 3DO viewer

Rick Stirling

Hi all, I've searched but couldn't find an answer. How to I invert the Y rendering of Normal maps in 3DO?

In Ndo I can flip how it processes the normal maps, but 3DO always seems to render them with a +ve Y.

I don't think there's a way to do it. I've just taken to working in +Y in NDO/DDO and then flipping the appropriate channel manually once I'm done.

DDO expects a +y normal to do its thing, so if you´re working -y simply check "Flip y" in the base creator and DDO will flip the normal for you. To flip the normal back on export this is up to the calibration profile, for instance the Unreal calibration profile does this automatically for you.

DDO needs the normals to be +y for a few technical reasons.

Hope this helps, let me know if you have any more questions
