Irrlicht Engine

we use mul to transform vector (v_pos) from 3D space to our 2d screen.

Does that mean if I use:
outPos = mul(v_pos, ViewProjectionWorldMatrix);
I have as result in outPos the 2D position on the screen of the vertex?

its still a vector with 4 components with normalized values from -1 to 1
the ...

Hi shaders are mostly math so its hard to get started
in hlsl:
struct_name.v_pos = mul(float4(v_pos, 1.0f), wvp_matrix)
we use mul to transform vector (v_pos) from 3D space to our 2d screen.

v_pos has x y z.
but for the shader vectors have 4 components: (x,y,z,w)

w=1 indicates that it is a vector ...

it should work if you use these settings:

You can also try the .b3d blender plugin (only for export):

I opened the Bullock.blend and exported with these settings and it played the animation
i think it was the "Export Skin Weights" option you forgot

Hi i am also new here
this code creates the cube and sets the texture you want


IVideoDriver* driver = device->getVideoDriver();
ISceneManager* smgr = device->getSceneManager();

IMeshSceneNode *meshnode = smgr->addCubeSceneNode(10,0,1,vector3df(5,100,25),vector3df(0,0,0),vector3df(5,5,5 ...
