Hi Jacobo, I'm glad you found out what the issue was! Hopefully it is a bug because LWO vertex normals are already complex enough as it is.

Modo was the first program that used vertex normals out of LWO format but unfortunately they decided to use them in the opposite convention of the rest of the coordinates (something like vertex position coordinates in left hand coordinates and vertex normals in right hand coordinates).

Then later on LightWave 9.6 also supported reading vertex normals out of LWO but they expect a different orientation than Modo. Then for some unknown reason they decided to change it to some other direction in LightWave v 10.

Hopefully Modo is not going to now throw in a 4th different possible orientation for the normals, since the current situation of having 3 different possible orientations to use is confusing enough as it is.

Modo 601 has not been released yet, so this must be a beta version? Jacobo's bug report will probably get it fixed before release. Maybe it would be worth passing on Michael's comments to the developers?

Hey Michale and Steve,

It sucks to hear about all the different ways to do that. I wonder why they decided to change it. Hopefully it's a bug and it will get fixed.
I've already submitted it and also asked if it was actually a bug or just a different way or reading those maps. I'll let you know how it turns out.

Thanks!

Hi Jacobo - someone else has written to me that Modo 601 seems to be using the LightWave v10 style orientation for vertex normals.

If you're using MoI v3 there are options for "Modo", "LightWave v9.6", and "LightWave v10" - if you set it to the LightWave v10 style does it then work ok for you in Modo 601.

Hey Michael,

I've just read that on the modo beta forum as well. That's a good thing then. I'm not using v3 unfortunately since I've just started evaluating it so I downloaded v2 trial version, but it's good enough to know that it won't be a problem.

Thanks for letting me know!
