AddAnimatedMeshSceneNode obj crash!

[Kikketer]

I have a scene running just fine if I use a .ms3d mesh and .png texture. But I need to use an .obj and .mtl.

After some work I narrowed down the problem:

Code: Select all

ISceneNode node = device.SceneManager.AddAnimatedMeshSceneNode(device.SceneManager.GetMesh(@"Turtle1.obj"),null,-1);

Console.writeline(node.ID);

The runtime error tells me that it is trying to reference a null object at the Console.writeline.

When I change the mesh to "Turtle1.ms3d" it works fine. (by the way I have the Turtle1.ms3d and the Turtle1.obj in the same folder)

Is there something different I have to do to use obj?? Please help!

Stats:
The obj was exported from blender
Using C# to write the code along with irrlicht.net

If you need more info let me know!

try exporting it from milkshape instead, irrlicht chokes on some types of obj

My modeler is sending me the meshes in .blend format. Is there a way to convert without havng to change the 3D animation suite that he wants to use?

[bitplane]

use blender 2.37 and the x exporter. I've never used it myself, but other people swear by it

This is starting to get frustrating...

I exported the model to .x and I can even view it in the Direct X viewer (when I double click on the .x file).

Still when I try to use it in the engine I get a null reference error. The crazy thing is, it still works if I use a .ms3d file that I downloaded.

I even imported the .obj version of my original mesh into Milkshape, saw it there, then saved it as a .ms3d. When I tried to use that version, it still crashed.

GRRR!

There is an update:

I didn't read the beginning of the error, it reads:

Code: Select all

Could not load mesh, because file could not be opened.: Turtle.obj
Could not open file of texture: Turtle.mtl
Could not load texture: Turtle.mtl

Then it goes on with the null reference, which makes sense because the mesh wasn't loaded.

Do I have to stick the .obj files into a differnt folder or something basic like that? I'm lost!!

Do I have to stick the .obj files into a differnt folder

no, if u can load a 3ds mesh from a folder and place ur obj model in the same folder and only change the irr code to the obj model, then u should be in the clear -however, as someone already told u 'obj' is not a unique formate.
the 'obj' file u have may not be a wavefront obj ('proper' obj) so ur turtle may simply be in a format irr can not handle
Can u open turtle.obj in anim8tor? ..if u have it (freeware)
