Wrong rotation values in Blender GUI

Well, today I successfully found out why the rotation does not work in my script if I try to replace some brick: it is because of LDR Import script - although it places all the bricks in the exact right rotation to the scene it states brick's rotation values wrongly in Blender's GUI in object rotation fields where all bricks are stated as their rotation is always 0, but it should correspond to .ldr brick's rotation (which is not), and therefore newly replaced bricks are always not rotated (rotation = 0) simply because of this fact alone I am not able make my script rotate replaced bricks right upon old bricks rotation values...and I think this could be clearly taken as a bug in LDR Import addon scrip

You could have a look at my version of the importer in #69. I corrected this and some other stuff.

I would like to but where to download your version? When I open that link there is not link to your file

I think I understand your issue. For example, if you rotated a brick on it's side in MLCad (or another LDraw program), you want the brick to be set to that rotation in Blender. Basically, Blender is applying the rotation of the brick so it says 0. (I guess that's right?) We will look into this. Currently, we are working on a new rewrite (look in the rewrite branch of the repo) and it should fix lots of issues. I think I'll label this to be fixed in the rewrite. :)

@rioforce yea, you got it right, that is what I meant, see: as I said elsewhere I made addon that works together with your importer and part of it was that it automatically replaces all bricks from my array with bricks from external .blend file having for example grain on skew part on slope bricks etc., but I was facing this proble mthat bricks were replaced very fine except the rotation

Sorry, I assumed you knew github.

Here's the link to my fork: https://github.com/Banbury/Blender-2.6-LDraw-Importer/tree/rewrite

Copy the io_ldraw folder into the addons folder:
c:\Users\AppData\Roaming\Blender Foundation\Blender\scripts\addons\

Banbury, I tried your importer on Car.dar, and the headlight 1x1 rounds plates are set to the 90 degree rotation, unlike what bublible was talking about. He wants the rotation to not be applied to the brick.

yea, what we need actually to do is just SET THE ROTATION NUMBER VALUE to the corresponding field in Blender GUI WITHOUT REAL RE-ROTATING...so I think you can rotate it in the script so it becomes prerotated "wrongly" by the amount needed as value for GUI rotation field AND AFTER THAT actually physically rotated it by setting the right value to the Blender GUI ;) ...that way the bricks will be rotated as they should + they will have also the right rotation value in the Blender GUI

hey guys, to me just as a concept, it looks quite easy:

• when taking rotation data from .ldr file save it to temporary variable - maybe even array, then set rotation to 0, so when placed to scene they will be wrongly rotated for a while...
• after physiscal placing the model to Blender scene APPLY those variables for all bricks and that will make the magic for us having our bricks still rotatetd right but having their real rotation values in Blender GUI... ;)

See I would do it for you myself like no problem,,it is quite easy part, BUT I am really new to Python so I do not know which part of your importer deals with .ldr rotation values...actually Imsaw something as matrix which values looked to me as it could have rotation to it but never figured out how it works, but I guess you know so here are my two cents...

[rioforce]

Yes, I struggle at times with Matrix. Like I said, we'll look into this. This could be a valuable feature. I'll see if I can look into it maybe tomorrow. :)

@rioforce great, just let me know if you will then, please

I forgot to tell you, I looked into the Matrix rotations in the normal script (not the rewrite), and I couldn't get it to stop applying the rotation. Too many things rely on it. :P I'll have to look into it again, and see if I can fix it in the NextGen rewrite script. :)

pitty there is non one who would be able explain me how the Matrix thing work, maybe if I understand it I could play with it too
