Hi there

I´ve always worked in 2d because the Z-factor alone scares the shit out of an old guy. But no play, no game. So I want to dive into the z-factor. But in my humble beginnings, I need a little guidance. There are so many formats to choose from. Kudos to agk for supporting them. But what should I go for?

I work (PLAY!!) in blender. I made a simple globe with an earth texture. I´ve saved it as both a blend file, and a blend file with the texture packed in. I´ve also exported it to the .obj format which also produces an .mtl file. I tried to load the .blend file with load LoadObject, with no luck. I dont see an object. The .obj. file worked.

Now, my questions is....

1. what format (recommended) should I use when exporting and why isn't the .blend file showing?
2. When exporting single objects, like my test-globe - should I delete every camera and light in the scene?
3. Is it important to centre the object in the world before exporting?
4. What is the mtl file produced when exporting as .obj...

Hello Tim
I am excited every time I hear someone is moving into 3D.

I'm not the most expert but I do have some expriance.

first of all
download AppGameKit 2.015b , so 3d physics will work and all new 3d commands.

second ,
when exporting from blender
.blend is a blender only file
you need to export to .dae
this is the new mainstream blender export for games and movies.. I know some uses the old formats which they are use to but the .dae is pretty simple , good and you can edit it outside blender inside the .dae file itself (xml).
third do not be afraid to play with all the 3d commands AppGameKit posses you might find it easier to understand then you think.

and the Cherry, write done Mixamo Fuse on google.. and get it while it is still free. you will be able to create wonderful 3d characters that you create and modify (you can modify everything) then export it to dae and play with it inside AGK.
do not forget inside FUSE preferences to click on "Pack Textures" as this will pack you character textures into 4 images that you then load with SetObjectImage(obj,IMG,shader) so you get a normal , specular and gloss I think..

hope this helps.

According to the documentation the supported formats are .X .3ds .md3 .smd .md5 .lwo. .ac .b3d .dae .3d .lws .ms3d .blend .m3 .obj and .ago. Yes collada is a standard format, but a .blend file should work.

I've been using .obj exported from blender for all my agk projects without any problems - V1 and V2 although I've yet to try the new 3D commands in v2.15b (I'm still using 2.14b).

Depending on what you're doing in Blender, you can just export the entire model. I've attached an image of the options I choose when exporting. You can also tick the "selection" box if you only want to export a part of the of the model.

I've not had a chance to try other formats yet so obviously this doesn't include animated models but it's a start.

Thank you, 29 Games. That is really helpful. Just what I wanted.

I´ll just go for the .obj format.

I should have added, you don't need to delete the light or the camera from the blender model. You'll need these if you plan on baking textures.

Also, at the moment I'm just applying the textures in AppGameKit using the SetObjectImage command.

This is really cool! One problem though...

Exporting to .dae from Mixamo saves the anims as separate files, with only the bones. As AGK2 cannot load anims into 3D object (yet?) this is useless for animating our Fuse characters.

Unless you know of a method to get the Fuse/Mixamo animated objects into another format that includes the anims in the object?

I would SO like this to work, even when they go to a paid version, the Fuse/Mixamo combo is really easy to use.

EDIT: Just a warning. Installing FUSE with my Adobe ID invalidated my licensing on Photoshop. I had to use the license recovery tool to get Photoshop CS4 working again!
