I'm trying to import this bike. It worked fine but then i modified a bit the mesh hierarchy in blender, reexported as collada, and then the textures started having problems. I could not understand what caused it but i didn't touch in any way textures, materials or techniques.
Does anyone know what this could be?

[Jagerbomber]

I think it's because

giucam, after adding some vertices the whole UV-map needs an update. Because the old uv-map has to handle with less vertices. So it doesnt fit to the new mesh. Or what do you mean with hierarchy?

[giucam]

No, i didn't modify the meshes, i just changed the positions and the parent/child relationships:

[necro]

oh, then it depends on the importer i guess. Do you have multiple texture files for within the object?

[giucam]

Actually it has no textures, only solid color materials.

EDIT: I noticed that if i do "Apply location" in blender i also see that effect.

[necro]

But apply location does not impact textures. Thats strange.

Could you send me the .blend file? I could check this then.

[giucam]

Sure, thanks: https://www.dropbox.com/s/ehmclhqnscf5knv/untitled.blend

Ok, i could figure out the problem. This model has wasted normals. Actually someone has to recreate the model completely. The problem is, that this model only has triangles - no quads. Therefor blender is confused about the normals.
I'll see, what i can rescue, but it needs time


This is what i could rescue so far - but some parts need a complete recreation.

Either your grass is shorter than mine use to be or that thing is HUGE

[necro]

Lol, i didnt recognized it, but you are right. The bike has correct proportions, so i guess the grass is shorter.


but there is no parameter for that ^^ so its surely the bike, which isn correctly proportioned.


This is the tree as reference:

Just spawn the 8x8 behind the bike.

[necro]

I thought the tree would be evidence enough, but just for you i post a nice foto ^^

[giucam]

LOL yeah, that bike is quite big. I've found 0.15 to be a quite good scale factor.

Thanks a lot necro! I've also found a way to work around it: I export the correct hierarchy from blender, then i manually edit the original and the new dae, I copy the hierarchy over the original dae, adjust some things and voila! It's quite a cumbersome work though, I'm still halfway.

....just a little bit, a tiny, wemy wamy minuscle piece of a bit - bigger than it should. Simply said: an ogre giant could not ride that thing.
