Hi! I've tryed writing on the youtube video but seems the commet are disappeared.

The problem I was asking is that i can't get the color attribute to the points, I've defined the shader with the "attribute" "Col" as base color, and then the geometry node both with instance or mesh to points, but the points still has no colors

May I ask for help? Thanks :)

Certain JWF formulas will place additional nonstandard property fields into the PLY file when exporting. This was reported by Brad Stefanov on Feb 4 2022 and replicated on my end. Patched in v1.01, will revisit for more comprehensive solution.

I've been working on a ply writer for some particle simulation data which can map one attribute to RGB, another to alpha, and a third to emission. With very little coding experience myself, I've been working on a personal set of edits to this reader for an additional column but I figure this may be something useful to others as well, hence why I bring it as a suggestion here.

Hello,

Thanks for such nice tool.

I have some problem when import the pointcloud as it seems it modifies the coordinates while importing. In the image, you can see that in blender (left) the two models do not overlap as they should. When open the models on meshlab it does work (right image). Is this a problem that can be solved?

Best, Bryan

Hi, thanks for creating this updated ply importer! I wrote something that creates a material and geometry node tree:

import bpy

mat_name = "pointcloud"
materials = bpy.data.materials    
if materials.get(mat_name) is None: 
    print("creating pointcloud material")   
    mat = materials.new(mat_name)
    mat.use_nodes = True
    materialtree = mat.node_tree.nodes
    materialtree.remove(materialtree.get("Principled BSDF"))
    materialtree.remove(materialtree.get("Material Output"))
    
    attributenode = materialtree.new(type="ShaderNodeAttribute")
    attributenode.attribute_name="Col"
    outputnode = materialtree.new(type="ShaderNodeOutputMaterial")
    pbrnode = materialtree.new(type="ShaderNodeBsdfPrincipled")
    mat.node_tree.links.new(attributenode.outputs[0],pbrnode.inputs[0])
    mat.node_tree.links.new(pbrnode.outputs[0],outputnode.inputs[0])
mat = materials.get(mat_name)

#import object
bpy.ops.import_mesh.ply(filepath=r"C:\Users\User\Desktop\file.ply")
importedObject = bpy.context.active_object
#create geometry node tree
bpy.ops.object.modifier_add(type='NODES')
nodeTree = bpy.context.active_object.modifiers[0].node_group

cubenode = nodeTree.nodes.new(type="GeometryNodeMeshCube")
CubeSize = 0.001
cubenode.inputs[0].default_value[0] = CubeSize
cubenode.inputs[0].default_value[1] = CubeSize
cubenode.inputs[0].default_value[2] = CubeSize

instancenode = nodeTree.nodes.new(type="GeometryNodeInstanceOnPoints")
materialnode = nodeTree.nodes.new(type="GeometryNodeSetMaterial")
materialnode.inputs[2].default_value = mat
shadenode = nodeTree.nodes.new(type="GeometryNodeSetShadeSmooth")
realizenode = nodeTree.nodes.new(type="GeometryNodeRealizeInstances")
geonode = nodeTree.nodes[0]
outnode = nodeTree.nodes[1]

nodeTree.links.new( geonode.outputs['Geometry'] , instancenode.inputs['Points'])
nodeTree.links.new( cubenode.outputs['Mesh'], shadenode.inputs['Geometry'])
nodeTree.links.new( shadenode.outputs['Geometry'], materialnode.inputs['Geometry'])
nodeTree.links.new( materialnode.outputs['Geometry'], instancenode.inputs['Instance'])
nodeTree.links.new( instancenode.outputs['Instances'], realizenode.inputs['Geometry'])
nodeTree.links.new( realizenode.outputs['Geometry'], outnode.inputs['Geometry'])
