Hi, I am in need of a De-Triangulator, that turns double triangles into square for model optimization. does such a thing exist?

I have no clue, but...

which I got from

What modelling program are you using?

[Topgun]

Blender, but I also have wings 3d and truspace. what I need is to get rid of the diagonals.

Yup, the best way is to do it by hand than trust an autmated program to do it, else you get situations where it merges two triangles that are halfway across the UV map from each other, which totally fubars the texture.

Basically, you need to select the polygons in small groups, and use a tool that will be called 'merge polygons' or the like in the modelling program.

the model has 4000 polys. what is the automated way?

...Could you try selecting polygons in large groups??  (really large, if you don't like it, try the next level down).  I dunno...

[Turey]

why do you need to do this?

I've never done that, but there's maybe something to do this in the Scripts window or a python script to add this functionality.

Tried that, it no work.

I just found a quad --> Tri button in Blender. I tried and it did the job.

yeah, in blender Alt-J is tri -> quad and Ctrl-T is quad -> tri.
