LoadMesh and AddMesh problem?

I used createcylinder to make some tubes and combined them into 1 mesh with AddMesh no problems. I'm trying to load a mesh for the junctions between the tubes with LoadMesh (tried LoadAnimMesh too just incase) and it loads and displays fine but add mesh doesn't seem to do anything with it. I can scale the mesh, move it etc, all with the mesh commands, just not add it to another mesh.

Known bug? Am I forgetting a step?

You might be adding the meshes in the wrong order, i.e. mesh1.AddMesh(mesh2) rather than mesh2.AddMesh(mesh1)

Whether the mesh has been loaded or created shouldn't make a difference.

Double checked, adding in the same order I am adding the tubes that work.

AddMesh(Tube, GameMesh) ' works

AddMesh(Junction, GameMesh) ' doesn't work

So it's not addmesh that doesn't work, it' something possibly stranger.

the add mesh works, however if I apply a texture to the loaded mesh data it seems to vanish. If I load the obejct I can see it. if I texture it it goes away, that includes with wireframe enabled. I can load and add the mesh and see it, but if I texture the mesh I'm adding everything to then those loaded segments vanish but the rest gets textured and works. again, those segments are gone in wireframe mode too.

Don't suppose you could knock up a quick sample that reproduces the problem could you?

I'll see what I can knock together. I assume it's just my model however. I'm going to poke around at my .b3d exporter and see if I can get it working by playing with some settings. when I invariably fail there I'll put up a sample :0)

little demo stripped out of my app

W and S toggle wireframe and solid mode

T and C toggle the texture

A and D turn the camera


with the texture dissabled you can see the junctions, with it enabled they seem to vanish in both solid and wireframe.

Looks like it could be something with the texture coords of your junction model. Have you tested the junction model with a solid texture, so that you know it's right? And what 3D modeller have you used for the junction?

That's the trick. I forgot to map coords on the model entirely. I usually texture models in blender before I export them and somehow assumed it would have coords even though I never set them. Thanks Tue! problem solved.

I'm still a little confused about why it vanished in wireframe since I would think wireframe doesn't have anything to do with textures but apparently another bad assumption.

[solution] check your model, does it have coords?[/solution]
