ISceneManager->getMesh(file.3ds) always returns NULL

[gauravjha]

Hi,

I have been trying to load a 3ds mesh on a Win CE 6.0 device using Irrlicht v1.7.3. The ISceneManager->getMesh(mesh.3ds) is always returning NULL. I have checked and double checked and the mesh file is present at the location provided in the getMesh() function.

Can anyone suggest me if there are other reasons for ISceneManager->getMesh(mesh.3ds) returning NULL pointer?

Any help in this regards would be really helpful.

not being able to open the file
not being able to find the file
finding an error in the file

Can you see any console output? if so, provide it.

Maybe try with a .obj file instead, could be an endianess problem.

Hi,

While executing the program on the device, there is no console window. Is there a way to view the console messages on the device?

I am trying to view the room.3ds file available with the Irrlicht engine.

It does not matter which 3ds file you view, as all 3ds files are binary. Since we have a very simple mechanism of checking for endianess, wit might be wrong for your platform. This would lead to broken loading of several mesh file formats. So you should try to load a different type, which uses ASCII format. You can also load the dwarf.x provided in the media directory, should be ASCII as well.
You can intercept log messages in an event receiver and print them to the screen or use system log functions. The latter is platform specific, though.

Hi,

I tried the the dwarf.x file and it was successful on the WIN CE device.

Thanks.

Ok, I'll move this one to the bug forum then, as it should be a big endian problem in that case.
