May be a bug in CreateSurface ....

[Icare]

Hi

 

I'm thinking that I found a bug in object with multi surface...I found a temporary solution, but it's very strange, it looks like the surface doesn't reset after a create

 

In first time my code who created 2 plans and I assign 2 materials, but the second surface doesn't show correctly the material. And the screen shot

 

	_mesh = CreateMesh()

	surf = _mesh.AddSurface()
	surf.AddVertex([1.0, 1.0, -1.0], [0.0, 0.0, 0.0], [0.0, 0.0])
	surf.AddVertex([1.0, 1.0, 1.0], [0.0, 0.0, 0.0], [1.0, 0.0])
	surf.AddVertex([1.0, -1.0, 1.0], [0.0, 0.0, 0.0], [1.0, 1.0])
	surf.AddVertex([1.0, -1.0, -1.0], [0.0, 0.0, 0.0], [0.0, 1.0])
	surf.AddTriangle(0, 1, 2)
	surf.AddTriangle(0, 2, 3)
	mat = LoadMaterial("abstract::skyright.mat")
	PaintSurface surf, mat

	' Front Face
	surf = _mesh.AddSurface()
	surf.AddVertex([1.0, 1.0, -1.0], [0.0, 0.0, 1.0], [1.0, 0.0])
	surf.AddVertex([1.0, -1.0, -1.0], [0.0, 0.0, 1.0], [1.0, 1.0])
	surf.AddVertex([- 1.0, -1.0, -1.0], [0.0, 0.0, 1.0], [0.0, 1.0])
	surf.AddTriangle(0, 1, 2)
	surf.AddTriangle(0, 2, 3)
	mat = LoadMaterial("abstract::test.mat")
	PaintSurface surf, mat

 

And the screen

 

the solution, I must Create two Time the First vertex on the second surface

 

	_mesh = CreateMesh()

	surf = _mesh.AddSurface()
	surf.AddVertex([1.0, 1.0, -1.0], [0.0, 0.0, 0.0], [0.0, 0.0])
	surf.AddVertex([1.0, 1.0, 1.0], [0.0, 0.0, 0.0], [1.0, 0.0])
	surf.AddVertex([1.0, -1.0, 1.0], [0.0, 0.0, 0.0], [1.0, 1.0])
	surf.AddVertex([1.0, -1.0, -1.0], [0.0, 0.0, 0.0], [0.0, 1.0])
	surf.AddTriangle(0, 1, 2)
	surf.AddTriangle(0, 2, 3)
	mat = LoadMaterial("abstract::skyright.mat")
	PaintSurface surf, mat

	' Front Face
	surf = _mesh.AddSurface()
	surf.AddVertex([- 1.0, 1.0, -1.0], [0.0, 0.0, 1.0], [0.0, 0.0])
	surf.AddVertex([- 1.0, 1.0, -1.0], [0.0, 0.0, 1.0], [0.0, 0.0])
	surf.AddVertex([1.0, 1.0, -1.0], [0.0, 0.0, 1.0], [1.0, 0.0])
	surf.AddVertex([1.0, -1.0, -1.0], [0.0, 0.0, 1.0], [1.0, 1.0])
	surf.AddVertex([- 1.0, -1.0, -1.0], [0.0, 0.0, 1.0], [0.0, 1.0])
	surf.AddTriangle(0, 2, 3)
	surf.AddTriangle(0, 3, 4)
	mat = LoadMaterial("abstract::test.mat")
	PaintSurface surf, mat

 

And the screen

UpdateMesh ( mesh )

Did you updated the mesh?

[Icare]

Yes , There is no change with updatemesh .... And a mesh with multi surface exporter with Leadwerks tools 2.2 for 3ds max doesn't work too.
