FOSS gamedev and creative worlds

Hi,

I made a chicken to run around in MT and for some reason it's moving backwards even though in Blender, the orientation of the model is right.
Also, there are gaps in the texture at the edges of the model, even though there are no gaps in the texture file itself.


(Look at the beak.)

The model is made in Blender and exported as a DirectX file.

Any help with these issues will be greatly appreciated.

The gaps are probably caused by non-manifold errors in the mesh as for the direction, minetest is just weird like that and it's unlikely to be fixed for legacy reasons. Just rotate the model in Blender before you export.

I checked for non-manifold errors and none turned up, so I guess that's not the problem.

Just noticed that, in fact, the chickens are floating. Any idea what's the cause of that?

The only other thing I can think of is a UV mapping error, use snap-to-pixels to make sure you've not mapped any of the transparent background.
For floating chickens, I'd need to see some code. I don't think that has anything to do with the model itself.

Perhaps you need to tell them about gravity?


Edit: Be sure to set physical=true if you do that or your 'chickens' will disappear into the ground forever...

Maybe I should've added that the texture error only occurs in MT and not on the actual model in Blender.

Sorry , I am not sure why that would be. If you upload your .blend file, maybe I or someone else can figure out what is causing the problem.

There you go. : )

I know that one of the legs is not appearing because of a missing texture, and the armature isn't working right at the moment, my focus lies on the texture errors which e.g. occur at the beak and seemingly only in MT.

Ok I think I've got it, your texture has a partial transparency around the lower beak area, unfortunately minetest does not support partial transparencies on entities and will display them as fully transparent, hence the gaps.

Thanks, that was the problem! :D
My chicken's now happily running around without any holes.
