I bought ultimate unwrap today and I made a texture file for a character, but when I apply the texture I cant see the character any more.

The code is

[Code]
guy=loadmesh("wingman.3ds")

guy_tex=loadtexture(wing_map.bmp")
entitytexture guy,guy_tex
[/Code]

Works fine without the texture.

ext: .bmp or tga file
size: 1024,1024

the mesh was created in wings

you forgot a " in the filename ... but i don't think it's the error, however it would return an error while compile the program.

Maybe you specify a mesh that have no UV Coordinates => result is all uv are setted to 0,0 , and generally corner of textures are black. If you have a black background viewport, you won't see your model.

Fuller,

did you texture it in Unwrap? If so just export from UU3d as a B3d and load that mesh instead.

Check all textures are in the same folder as the mesh and the filenames have to be 8.3 btw. Also move the camera back a forwards incase something has happend with the scale of your model.

This will draw the UV map on screen, use it to see if there is a correct UV map or not. Replace CreateSphere() with LoadMesh("yourmesh.x") e.t.c

Graphics3D 1024,768,32,2

mesh=CreateSphere(16)

drawUVs mesh,512,0

WaitKey
End


Function drawUVs(mesh,scale,uvset)

	surfCount = CountSurfaces(mesh)

	For i = 1 To surfCount
		surf = GetSurface(mesh,i)
		triCount = CountTriangles(surf)

		For j = 0 To triCount-1
			u0# = VertexU(surf,TriangleVertex(surf,j,0),uvset) * scale
			v0# = VertexV(surf,TriangleVertex(surf,j,0),uvset) * scale

			u1# = VertexU(surf,TriangleVertex(surf,j,1),uvset) * scale
			v1# = VertexV(surf,TriangleVertex(surf,j,1),uvset) * scale

			u2# = VertexU(surf,TriangleVertex(surf,j,2),uvset) * scale
			v2# = VertexV(surf,TriangleVertex(surf,j,2),uvset) * scale
			
			Line u0,v0,u1,v2
			Line u1,v1,u2,v2

		Next
	Next
End Function
