ofxAssimpModelLoader positions don't match?

Hi OF !

I’ve found something that i can’t understand …
I’m loading a simple 3D object with ofxAssimpModelLoader … it’s a cube centered in origin with sides of 100.0 length.

The strange thing is that if i draw something in OF on the position (50,50,50) which might be one of the vertexs of the cube, if i get close to it, both positions doesn’t match … so my (50,50,50) node it’s not in the same precise place as the vertex coming from the model loaded …

Some pictures to illustrate it :

?¿? I don’t have any scale or translation going on, just load model and draw …

Drawing in all of the corners seems like the 3D model read from the OBJ it’s slighlty bigger than what it should ?¿ Here is a picture where with a wide lens i can see all the vertices of the cube and my corrsponding marks slightly inside of the cube …

If i open the OBJ with a text editor i can read that the coordinates of the cube are ok … so like (50,50,50) …
And i’ve also tested with the OF example of the ofxAssimpModelLoader and i got similar unaccuraccy ?

Has anyone find something similar ? Is there something i’m missing ?

thanks !
