Imeshcvt in irrb doesn´t work

[RobbyRob]

Hello,

RobbyRob has a little problem installing the imeshcvt plugin for blender getting this nice and fast binary mesh files;
I set the environment variables to IMESHCVT=c:\irrbutils\imeshcvt.exe and in the render menue I got the bottom "create binary meshes", so farwell, done,
exporting .irrmesh works great, but no .irrbmeshes will be created in my scenes file and the console says
input mesh: -v
output mesh 1.6
Error input mesh doesn´t exist,

the rest is really great work !!!

anybody an idea what happened or how to solve it

Thank´s for every support

RobbRob

Hello RobbyRob - It looks like you're using an older version of imeshcvt so you'll need to replace it with the latest version from: irrbUtils-0.4-win32.zip.

Hi pcOde.

thank you for your answer. I did it, but same result, I used the latest version, but there wan´t be an irrbmesh in my folder; it´s strange that the button is in the render menue, but no result, I will work on this problem, if anybody else has an idea, everything s appreciated

It may help if you email/pm me your "irrb.log" file. It's saved in the "Output Directory".

Hi PcOde again;

it´s nice that you care about my problem, so here is the .log file content:

Remove the "-v" in your IMESHCVT environment variable. It should be:

IMESHCVT=C:\Python25\imeshcvt.exe

[RobbyRob]

Dear pcOde,

it´s as simple as can be; the reason for the error is python itself, blender console says it could not find "mesh input" and my file path starts with "Dokumente und Einstellungen" but python doesn´t forgive any empty space in the file names;
so I changed to python\scenes\mdl and the binary was created succesfully,

yes we can, thank´s again for any support

Robert

So there were a couple of things happening here. The first was the "-v" parameter erroneously included in the environment variable. irrb automatically adds the version parameter when invoking imeshcvt and this is why you were originally seeing:

Code: Select all

input mesh: -v
output mesh 1.6
Error input mesh doesn´t exist,

The second problem is a bug in irrb in that the irrb->imeshcvt call isn't taking into account spaces in the "Output Directory'. This had been fixed in 0.5.

Thanks for bringing this to my attention RobbyRob.

Hello pcOde,

it´s me again, now I tried to implement irrbmesh into my code, but I but I have some trouble with this code fragment in the irrBMeshWriter.cpp

Code: Select all

void CIrrBMeshWriter::updateMaterialLayer(const video::SMaterial& material,u8 layerNumber, irr::core::stringc& textureName, struct IrrbMaterialLayer_1_6& layer)
        {
            if(layerNumber > 3)
                return;

            memset(&layer,0,sizeof(layer));

            textureName = material.TextureLayer[layerNumber].Texture->getName().getPath().c_str();
            layer.mBilinearFilter = material.TextureLayer[layerNumber].BilinearFilter;
            layer.mTrilinearFilter = material.TextureLayer[layerNumber].TrilinearFilter;
            layer.mAnisotropicFilter = material.TextureLayer[layerNumber].AnisotropicFilter;
#if IRRLICHT_VERSION_MAJOR == 1 && IRRLICHT_VERSION_MINOR <= 6
            layer.mTextureWrap = material.TextureLayer[layerNumber].TextureWrap;
#elif IRRLICHT_VERSION_MAJOR == 1 && IRRLICHT_VERSION_MINOR == 7
            layer.mTextureWrap = material.TextureLayer[layerNumber].TextureWrapU;
#endif
            memcpy(&layer.mMatrix,material.TextureLayer[layerNumber].getTextureMatrix().pointer(),sizeof(f32)*16);
        }

the errors are:
getPath : is not a member of irr::core::string<T>
left of .c_str must have class/struct/union type
[/code]

So I guess I am missing a header file, but I don´t know, where getPath is included;
I included all the headers which are neccessary for the fileloaders and writers and check it double,

do you have an idea, what went wrong?

Thank you for your help,

RobbyRob

Hi again,

now I can answer the question myself, it is very easy, just cancel getPath(), because this method does not exist and the compiler is quite satisfied;
now my program runs perfectly and I fall in love with these binary meshes, very fast and accurate, great job pcOde...

and now I go to bed, because it´s late, I am 46 and I have to do a hard job tomorrow,

till soon

RobbyRob

My bad, obviously I didn't test against 1.6 and it looks like getPath() was added after that. The quickest fix for you would be to update to the 1.7 release of Irrlicht. If that's not an option, I should be able to modify it for 1.6 within the next couple of weeks.

Also I'd like to reiterate that the .irrbmesh format is still experimental. In fact, I don't like the code for handling structural changes between versions so that's going to be removed/replaced. Still working it out in my head...
