Can't find filter: Parametrization: Trivial Per-Triangle

[Ethanol10]

Hi, so i've started using this as a way to automate vertex color to texture operations, but when performing Parametrization: Trivial Per-Triangle filter and filter Vertex Color to Texture, it can't find the filters and halts.

When using the Vertex Color to Texture:

`(base) PS C:\coding\meshlabxmltesting> python main.py
meshlabserver cmd = meshlabserver -i "quatrefoil_color.ply" -o "final.ply" -m vc vn wt -s "C:\Users\ethan\AppData\Local\Temp\tmpuv09xnii.mlx"

Houston, we have a problem.

Here is the snippet of code I used, it's based off the example in the folder, hence why there are some similar variable names:

def main():
    os.chdir(THIS_SCRIPTPATH)
    #ml_version = '1.3.4BETA'
    ml_version = '2016.12'

    # Add meshlabserver directory to OS PATH; omit this if it is already in
    # your PATH
    #meshlabserver_path = 'C:\\Program Files\\VCG\\MeshLab'
    #"""
    if ml_version == '1.3.4BETA':
        meshlabserver_path = 'C:\Program Files\VCG\MeshLab'
    elif ml_version == '2016.12':
        meshlabserver_path = 'C:/Program Files/VCG/MeshLab'
    #"""
    os.environ['PATH'] = meshlabserver_path + os.pathsep 

    file_color = 'quatrefoil_color.ply'
    # Cross section parameters
    length = math.radians(360)
    tube_size = [10, 10, length]
    segments = [64, 64, 720*2]
    inner_radius = 2.0

    quatrefoil_color = mlx.FilterScript(file_in=file_color, file_out="final.ply", ml_version=ml_version)
    mlx.texture.per_triangle(quatrefoil_color, sidedim = 0, textdim = 4096, border = 0.1, method = 0)
    mlx.transfer.vc2tex(quatrefoil_color, tex_name="final.png", tex_width=4096, tex_height=4096, assign_tex=True, fill_tex=True)
    # mlx.create.cube_open_hires(quatrefoil_color, size=tube_size, x_segments=segments[0], y_segments=segments[1], z_segments=segments[2], center=True)
    quatrefoil_color.run_script()

The commented out command "mlx.create.cube_open_hires()" works fine, but when using the other functions in texture, it mentions it can't find the filter.

Sorry for the multiple edits, I was figuring out the formatting.

Which version of MeshLab are you using? It's likely that the upstream filter name has changed and I haven't updated MLX yet.

[Ethanol10]

MeshLab 2020.07 I believe.

[3DLIRIOUS]

Are you able to use the older 2016.12 release? This is the last release MLX was regularly tested with.

[Ethanol10]

I'll try grab a copy of that tomorrow when I get back on.

Hi, I found a copy of MeshLab 2016.12 and ran the following code again. This is the output.

Ok, this should be fixed in 2ae3974fc46dfef80af57da4f0ed2fd14bb101db. If it still doesn't work please let me know.

Forgot that Vertex Color to Texture needed fixing as well; this is now corrected in 2a26c1ff8b1ff14086eb96b54f8fde340cf55f36.
