Latest Blender Export Script [Wed Aug 25, 2010 - v1.4]

[SRombauts]

@SRombauts I'm pretty sure you just linked to an exporter that's unrelated to the one that is being discussed here.

Yes I understood that too, but it could help Onsokumaru.

Look HERE

So...... This should mean that some kind soul could make a 2.5 Blender exporter now eh? If we bribe them or something

We already have a not so bad exporter compatible with Blender 2.56+SVN r35672 (not so far from the 2.57 r35899), and I'll update it as soon as possible

First release for Blender 2.57 is out, please give it a try : http://www.ogre3d.org/forums/viewtopic. ... 18#p424018

Wow that was fast! Thanks I'll give it a go as soon as I can.

Hi guys, I've been trying to install the script, however, the readme says to copy the OgreMeshy folder to C:\Dependencies, except there is no dependencies directory on my computer. nor is there one located in my blender directory, nor in the ogreSDK folder either. Am I supposed to create that directory or what? Help is greatly appreciated.

[SRombauts]

Hi guys, I've been trying to install the script, however, the readme says to copy the OgreMeshy folder to C:\Dependencies...

It says "... copy it to C:\
Dependancies ...", it might be a problem with Linux endlines and your editor...
But in fact all this is optional and configurable in the blender2ogre.cfg

[mortalhuman]

Hi, downloaded and extracted the script to my blender addons folder,
enabled the script in the addons manager within blender,

Can export, only need to export .mesh with it, figured that out, at least the basics though I haven't messed with the options, looked for tangent calc/rotated tangent calc, other things that may be useful.

So far it's cool, but one problem: I don't see any interface changes, and I don't particularly like the interface being changed, being new to blender and all. But is it supposed to change the interface? There is an image that seems to point out new buttons and stuff within blender, but I didn't see new buttons?

Thanks for your work so far, it probably could be streamlined or given its own floating panel, but it's good work.

edit: actually, I can see now, there are errors when I push buttons and the interface has too many buttons/redundancy now, something is wrong, scaring me away from this script, very saddening, as it appears it's the only real option for 2.57. Looking forward to trying updated versions still.

[GenesisRage]

no this export script is for 2.49 not 2.57
there is no official 2.57 exporter yet, lf3thn4d is still working on it
there are 2 other exporters floating around that work with 2.5x but havent used them in a while so not sure of their current status

I have a question about bone parents.

In my model none of the bones have parents because I move them around manually. I notice the blender exported XML file says

Code: Select all

	<bonehierarchy>
	</bonehierarchy>

I ran into a problem where my converted models would act as if bone index 0 was the parent of all the rest. Could there be an error such that either Ogre or OgreXMLConverter will treat bone 0 as a parent to all bones who have no parent?

[zeromath]

im not sure how exactly to state my problem...

right now Im relying exported .mesh models from blender to my programmer, who then in turn puts the .mesh file (with .material and textures) into his ogre powered engine then send me back screenshots. the thing is, he says the models I provide him with do not export the normals correctly he is unable to apply shaders to the models (like toon shading, etc)

I made sure the models have their normals recalculated to face the right way but it still gives the same problem. Can someone help me? Is the .material file that could be the problem? I would send some screenshots and paste some code but Im not at my working computer atm....

[mkultra333]

You can have a look at the .mesh.xml file and see if the normals look alright. That might give you some hint about where the problem is.

Try making a cube and sending that to your programmer, after checking the normals in the xml. That might make tracking down the normal problem easier. Send the programmer the xml too so he can have a look.

[zeromath]

Thanks for the reply, but I wouldnt know what I would be looking for in the .xml file....I'm srry I'm not a programmer in any capacity

[zeromath]

Hey sorry for the double post:

My programmer told me that the reason why the .mesh/.material file can't support shaders: He said it's because I exported using ogre verson 1.4 while he is using ogre 1.7...Is there anything I can do to use ogre 1.7 to export the model?

[LiMuBei]

Get the latest Ogre command line tools with the 1.7 OgreXMLConverter. That should enable you to export 1.7 mesh and material files.

[menglixiaoyi]

Install:

1. Download python and install: http://www.python.org/download/ (Note: Get v2.6.4. Blender is compiled against v2.6. Hence only this version will work.)
2. Copy the the script and all subdirectories either into ".blender/scripts" or the user defined scripts directory.
3. In the "Scripts Window" run "Scripts → Update Menus".

I don't know how to implement these steps, please show me thanks. If possible , put a picture of howto do , such as where is "Scripts Window", How does " the script and all subdirectories " refer to ? Hope you reply, thank!

Seriously: You've got to show some self-initiative. Then things you asked about can easily be answered by a bit of effort from your side!" E.g. just use google with something like "Blender Script window" and it should solve that "mystery" .

[Ilovechocolat]

Hello World !

First sorry for my poor english.

I used this add on for export static meshs and it worked very well !

But when i try to export skeletal animation, i have a strange result, the mesh export is correct but when i apply my animation, the vertices become crazy.

I made you a screen, at the top you have the mesh without any modification and at the botom, you have the mesh with a simple idle animation :

PS : We dont se it on the screen but the bottom mesh is entirely symmetrical.

I hope you could help me !

[mkultra333]

It's possible you've got bone movements/scaling done in Object mode instead of edit mode. Have a look at the skeleton.xml file and see if the bone positions there are the same as what they are in blender.

[Ilovechocolat]

Yes your right, the bones positions in my .skeleton.xml file are looking strange, this is a part of the file :

A lot of bones have 0.00 position, maiby it came from it.

My Mesh and my skeleton are scaled to 1:1:1, positioned to 0:0:0 and rotated to 0:0:0 in object mode, i tried with and without 'link scale' option, my armature modifier have 'Vertex Group' and 'B-BoneRest' checked (i saw it in the exporter's documentation)

I got a problem when I tried to export a human model from blender it doest include the animations. I am using the Makehuman as a model. Then error is something like this

That's a make human materials problem, you need to create your own materials for use in OGRE, there are some problems with the materials directly from MH.

I got another problem I tried to export the Sinbad.mesh to ogre using blender export. Im using blender 2.49b and the error is about the materials thingy, The texture for the sinbad hasnt been exported or something like that.

[Mafioso]

Hello guys (if someone is still here),

I'm using 2.49b blender and the old exporter for it. I'm trying to export a path as a mesh. In other words I have an edge loop with no faces, just one vertex is connected to another and so on, I want to export it, but it seems that exporter does culling, so it removes all the vertices that aren't in a face, how can I avoid it? I just want a plain vertex to vertex thing. If anyone can help me with this and save my day, I would be really grateful
