Maya To Indigo Tutorial (coming...)

I think you need to set the Up Axis option to Z..
Even though you have Y as up in Maya.

Still got problems with the YZ up axis rotation

isn't it enough to multiply maya vectors by a rotational matrix?

R = 1 0 0
0 0 1
0 1 0

Yes, on objects..

But to rotate the camera it need to somehow reset the pivot pint and then translate, It is really hard

mm maybe if you explain better the problem I may be able to help you... I just had a robotics exam full with this kind of stuff

is the problem due to the fact that the camera is represented by both a rotation and a translation?

Yeah... Rotate and translate.
I made this to show

your problem should be solved by applying the rotation matrix both to the postion and the orientation vector of the camera

What does the diffrent numbers mean in the Rotaion Matrix?
(<rotation><matrix>1 0 0 0 1 0 0 0 1</matrix></rotation>)
How to rotate -90 around X? Need to know!

lego · Post by **lego** » Fri Nov 10, 2006 7:26 am

the numbers represent the versors of the system
x y z
1 0 0
0 1 0
0 0 1

a rotation of -90° around x should be

1 0 0 0 0 1 0 -1 0

or

1 0 0 0 0 -1 0 1 0

it depens on how the string is handled

p.s. I can't install maya with wine

okay... heh

Then I need to know 90X, -90Y, 90Y, -90Z and 90Z

Didn't under standhow it works

The camera is now correct, only the models left

Stupid Rotation Matrix...

When I use the -90X all the models get turned upside down...
What is 90X? ...and -90Y, 90Y, -90Z and 90Z?

I AM REALLY FREAKED OUT RIGHT NOW

After almost five months of wanting this too work...

AND NOW IT'S WORKING!!!!

YESS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

ahh....

lego · Post by **lego** » Fri Nov 10, 2006 11:11 am

yeah

I suppose you don't need the other matrices anymore

arneoog · Post by **arneoog** » Mon Nov 13, 2006 4:06 am

Just for fun I found the post where I first asked if this could be fixed

This is the date of the post: 27-05-2006 at 01:50 PM

Correcting the "maya Y" to "indigo Z"
It makes the Sky Light look really stupid

Could you try to add/fix that?

Hehe, that is well over five months

ive... never had the patience to fix the camera upvector bug... yet there it is! I stand in the light of your revelation

damn you, bugs!

edit- ARNE you have exactly 100 more posts than me

I am not sure if I use materials properly. I use Maya materials and I get the error:
No object matches name: LightLinker1.incandescence
And I don't know how to use Indigo materials.

Materials don't work
