Hi,
I haveshape points with type and height for individual trees.
I would like to know how to write a rule that I can use to place the .obj models using
the attributes from the shape-file. The points are loaded in CE at their right
locations.
I manage to
get the right height and rotate them use this rule from the forum, but I get
Unknown Texture… The mtl is in the assets folder.
attr Hojd = 0
attr TREETYPE = "Witch_Hazel_Model_0"
cowTex = ("assets/Trad/Witch_Hazel_Model.mtl")
getAssetPath = ( "assets/Trad/" + TREETYPE + "/Witch_Hazel_Model_0.obj" )
@StartRule
TREE -->
alignScopeToAxes(y)
s(0,Hojd,0) center(xz)
r(0,rand(360),0)
i(getAssetPath)
texture(cowTex)
Tree.
Best regards Tomas
First, omit the line "texture(cowTex)", since the model should have textures applied - the i() operation is all you need to get the textures.
Next, make sure the file "Witch_Hazel_Model.mtl" is in the same folder as the "Witch_Hazel_Model_0.obj"
This brings up another possible problem. I notice your OBJ file is "Witch_Hazel_Model_0.obj", but the texture file does not have"_0.mtl" at the end. That may or may not indicate a problem. Open the OBJ file in a text editor, and search for the string "Witch_Hazel_Model" (a few searches until you find reference to the ".mtl" material file). Does it say "_0.mtl" or just ".mtl" at the end? What needs to happen is that the OBJ file must find its texture file. I'm seeing a possible path problem, and a possible naming problem here. Try those and let me know.

Tanks for quick respons:)
I am new to programming, learning by the CE tutorials and at the same time building developments models at the goverment at Gotland, Sweden...
I found this rule that I manage to change it and to work as well:
attr TRAD = ("assets/Trad2/Witch_Hazel_Model_0.obj")
attr Hojd = 0
@StartRule
Point -->
alignScopeToAxes(y)
s(0,Hojd,0) center(xz)
r(0,rand(360),0)
i(TRAD)
