OGRE doesn't work

[Sebe]

I tried to get the OGRe examples to run but it seems the Load functions are broken. LoadTexture and LoadMesh don't work but the paths are correct For example LoadTexture in combination with CreateMaterial gives me the error: The specified TextureID is null.

[Kale]

Got any code?

[Sebe]

Well, nothing easier than that. Just take any of the 3D examples that come with PB 4.02, like:

That means that the specific texture is either missing, damaged or in some inappropriate format.

[Hydrate]

Are you by chance loading any of these from the help files? If so try not doing that, I had the same problem, loading it from the help file seems to load it into a tempory directory and its missing all the images etc.

[Sebe]

The textures are fine. I took a look at them and they are ok. The path is correct as well. There are other examples (sprite) that load from the same directory and have no problems. I also load the sourcefiles directly (not from the helpfiles). So it seems the problem lies within the 3darchive functions of the 3d engine (OGRE).

[Brice Manuel]

are you making sure you put the engine DLL into the directory of the source file?

[Fluid Byte]

are you making sure you put the engine DLL into the directory of the source file?

Why should he do that? He's just running sourcecode not a complied .EXE. Putting the Engine3D.dll in the sources directory is redundant because it's already in the compiler folder.

[Brice Manuel]

Why should he do that?

Why shouldn't he? Obviously what he is doing isn't working. When that is the case, you should try everything.

We are dealing with Windows, right? Its not like XP is even compatible with itself. There are all kinds of obscure bugs in Windows that will let something work for most people but not for one person.

Of course one could ask why he is bothering since the 3D support in PB is useless :roll:

Agreed!

Not useless, just "special". But oh well, that's another story and not the right place for such a debate.

[Sebe]

I already tried to put the engine.dll with the compiled exe in the same folder as the sourccefiles are. But the engine.dll is not the problem. I see the 3d preference option window and then even the 3d mode starts and shows me a white background with a black plane. I can even move the camera with the mouse and all. It's just the mesh and texture loading functions that are not working

What's your video card?

[Comtois]

I tried to get the OGRe examples to run but it seems the Load functions are broken. LoadTexture and LoadMesh don't work but the paths are correct For example LoadTexture in combination with CreateMaterial gives me the error: The specified TextureID is null.

Have you try MeshManual.pb example ? can you see the cube ?
May be you can try MouseOver3D in my signature, i use LoadMesh and LoadTexture and they work fine here with PB4.02

[netmaestro]

All is working here.

Video Card: ATI Radeon x1600

I have tried all OGRE examples that came with PB 4.02
Will try other examples like the ones of Comtois when I'm at home again (tomorrow).

@Brice Manuel: 3D support in PB is far away from being useless. The features surpass the ones from Blitz3D (physics, stencil shadows). Hopefully OGRE will be updated soon to support DX9 and shaders.
