View Full Version : Merge Script = Scale Wonkiness

Has anybody had any problems where merging files using a script under rare situations merges them extremely distorted?

It's really weird their "scale" values are exactly the same but the editable mesh itself is like 50% taller than it should be.

I can't create an exact sequence of events which causes it but I've seen it happen about 4 times over the last couple thousand merges.

Has anyone else out there seen this happen in Max 2008?

Weren't the objects parented to some NUscaled objects in the source file maybe?

might be different in the current session of max and the merged max file.

Does taller mean NU scaled? or just bigger... otherwise I'd go for aaachoo's suggestion.

Non-Uniform.

They have no parent in the source file. There's just a bunch of editable meshes all lined up nicely.

And the 'scale' is identical between the source file and the merged file. The mesh itself is transformed... but still based on the axis point.

(Time to go through the code line by line...)

Found the source of the problem I guess it wasn't on the merge:

$.transform = prerotateX $.transform 270

99.9999% of the time that works properly. But for some reason on this one object it doesn't work.

Any ideas on why this single object isn't getting transformed properly?


Edit:
Figured out the cause of the problem:

Create a cube. Move the verticies to make it oblong. Rescale it back to a cube. And apply the prerotatex operation. I thought that operator only applied a local X rotation to the object. The local scales are getting swapped around in the process... hmmmm....

Edit2:

Workaround:
s = $.scale
$.transform = preRotateX $.transform 270
$.scale = s
