Hi again.

Having problems with setNodeParamI, dont know how to use it correctly.

I try to change a material of my wall object (called wallNode), to make it transparent.

Code:

int wallNode = h3d.addNodes(h3d.H3DRootNode, wallRes);
transparentWallRes = h3d.addResource((int)h3d.H3DResTypes.Material, "models/transparent_wall.material.xml", 0);
Horde3DUtils.loadResourcesFromDisk(Settings.ContentDir);


// I have tried this
h3d.setNodeParamI(wallNode, (int)h3d.H3DMesh.MatResI, transparentWallRes);

// and this
// h3d.setNodeParamI(wallNode, (int)h3d.H3DMatRes.MatLinkI, transparentWallRes);

// and even this
// h3d.setNodeParamStr(wallNode, (int)h3d.H3DMatRes.MatClassStr, "Translucent");
//( class="Translucent" is the difference with original material and transparent_wall.material.xml)

I always get 'Invalid param in h3dSetNodeParam'.

I assume your wallRes is a Scenegraph and wallNode is a Model node.
Have a look at http://www.horde3d.org/docs/html/_api.html#H3DModel
It does not have a MatResI param, that's why you get the Invalid Param.
You can change the material resource on a Mesh node only.
If you only have a Model node at hand, use the h3dFindNodes function to search for your specific Mesh below the Model node.

Ahaa, I understand now little better that setNodeParamI method.

I wrote

Code:

if (h3d.findNodes(wallNode, "Rectangle01", (int)h3d.H3DNodeTypes.Mesh) != 0)
{
   int mesh = h3d.getNodeFindResult(0);
   h3d.setNodeParamI(mesh, (int)h3d.H3DMesh.MatResI, transparentWallRes);
}

and it worked. Thanks! :mrgreen:
