Grimrock

Hello,
I've problem with creating new model of secret button (or any button) for Eye of the Beholder wallset. I am trying to assign "temple_secret_button_large" animation to my model. I hope, someone from you can help me (especially @phitt, I see you make new models for secret buttons in your Mine tileset .

I'm using Blender to create the models, and the process: BLENDER export model to .dae -> GMT import model using assimp, change nodes, materials, etc. and save as .model for Grimrock. With door (gate) models I've no problem, just add some X-axis rotations to the process: BLENDER rotate model by X axis 90, export -> GMT import model, rotate root node (scene node) by X axis -90 and the door animation works fine in Grimrock.

But I'm really frustrated with the button animations on the new models.
I have two meshes: button frame mesh (wall with hole) and button mesh. Button mesh have the pivot at the same position as the temple_secret_button_large button mesh (to do this, I must export this model from asset pack, import to blender and get the position of the button mesh).


There is the model in blender format to download.

If I use the DAE export/import format, animation in grimrock is scaled, rotated, moved. I see in GMT (after comparing with temple_secret_button model), it can be some problem in node matrix. A can handle the animation in Anim tab (rotating and positioning) and save it as new animation, but this is not right solution, because it is almost impossible to set correct position of mesh in GMT.
If I use the 3DS export/import format, all meshes (nodes) have always the same pivot position as the root node in GMT.

Any tips, or simple "how to do new buttons using default animations" ?

I am not at home and I cannot test it, but you can try this:
- select and export 2 meshes (wall and button) as obj from blender
- import obj into GMT
- rename button to button_mesh
- load animation
- test it

Thanks Leki, but I don't have problem with renaming the nodes, of course my button meshes are always named "button_mesh" . And by the way, OBJ format don't support the multiple meshes/nodes (I think) and is useless in using with this type of objects like buttons/walltexts/etc.

Slovak version:
Myslim ze s tebou mozem aj v rodnom jazyku co som velmi rad Snad ti to takto lepsie vysvetlim, dufam ze som to v anglictine nenapisal nejako nepochopitelne.
Videl som tvoje objekty co si robil a Tombs of Winterfell a vyzera to skvele. Neviem ci si vsak uz skusal robit tlacitka alebo dvere. Ked robim novy objekt pre dvere, musim ho pred exportnutim v blenderi otocit (X axis 90) a nasledne v GMT otocit root node o -90 (a samozrejme premenovat node dveri na "gate") aby animacia fungovala spravne.
Myslel som ze podobne jednoducho priradim animaciu tlacitka novemu objektu. Animacia sa teda priradit da, ale nie som schopny dosiahnut to, aby bola spravne nastavena, cize v prislusnom smere a s prislusnou velkostou. Najlepsie by bolo ak si to vyskusas. Mam problem s presnym umiestnenim a otocenim tej animacie tlacitka.
Format OBJ myslim nepodporuje viac objektov, co som skusal vzdy mam po importe v GMT vsetky nody spojene do jedneho, neda sa teda na toto pouzit...

OK, here is answer in Czech

Hello John,
I have one feature request for GMT, with your OBJ import.
Can you add the other OBJ import option like "Import OBJ as new node"? (in the File -> Import menu).

Because of:
To create new model of the secret button with assigned one of the default button_press animation, I need to import 2 meshes (nodes) with the default (clear) matrix like 100|010|001. I'm using blender and only one exporting format, from which I'm able to import mesh with "clear" matrix is OBJ (using your OBJ importer). But for the OBJ format restrictions, there is only 1 mesh imported.

It is possible to create this sort of import meshes from multiple OBJ files? Added as new node with parent "RootNode".

Thank you for answer.

Not johnW.^^, but you can test if you can import the obj via assimp importer. This gets you more objects.
Ah, and i think you can move the button around, but not the root node, only the mesh itself. So root node stays as old position, mesh is at your desired pos.. will test that.

Thanx germanny, I don't know where I had my eyes, assimp importer supports OBJ
Tested and it works like a charm! Now I have completly new working model of the secret button in the game.

But another prob appears...
I see that the bounding box in the game (clickable area) is always taken from the animation and not from the mesh/node
If I create new button model with different dimensions from the original animation, clickable area in the game is still on position (and with dimensions) of the original animation...

- Import model as obj usig assimp (wall_mesh and button_mesh)
- load anim in GMT
- test anim - button will jump in different position
- select button_mesh and move (GMT animation tab) anim to the right place
- save animation
- create new game object and use your new animation in his definito
- hope it works, othervise you need "complete solution" (mesh and anim) as I said before

EDIT: it does not work - scale anim gives terrible results and target click zone is still in the size of old button. I am afraid you must go for a full solution.

This is a really great addition to Grimrock. I've been playing with it, but I'm not that technical a person, so I'm stuck until a manual can be made for it.

I've imported my cricket bat sword, but I don't know about bringing textures in and all that other stuff.
