I’m using CesiumJS to view point cloud based 3DTiles. I’d like to be able to toggle showing points in a specific color range but it doesn’t seem to work. Should the following code work to hide any points that don’t have a red value of 242? tileset.style = new Cesium.Cesium3DTileStyle({ show : “${Red} !=242” }); ---

Your point clouds tileset likely doesn’t have the `Red` property. You may need to access the `Color` property instead: ```auto tileset.style = new Cesium.Cesium3DTileStyle({ show : “${COLOR}.x !=242” }); ``` You may also have to change the 242 to its corresponding value between 0 and 1. We have a specification for 3D Tiles which you can access here: [https://github.com/CesiumGS/3d-tiles/tree/master/specification/Styling#point-cloud](https://github.com/CesiumGS/3d-tiles/tree/master/specification/Styling#point-cloud) ---

Thank you. Here are the values I’m seeing in the .pnts file being rendered. ## (py3dtiles) [ec2-user@ip-172-31-12-146 ~]$ py3dtiles\_info /lidar/cesium/6-61-28-29.pnts Tile Header Magic Value: pnts Version: 1 Tile byte length: 390622 Feature table json byte length: 144 Feature table bin byte length: 390450 ## Feature Table Header {‘POINTS\_LENGTH’: 26030, ‘RTC\_CENTER’: [-402461.359375, -5509823.703125, 3176833.640625], ‘POSITION’: {‘byteOffset’: 0}, ‘RGB’: {‘byteOffset’: 312360}} ## First point {‘X’: -3.470625, ‘Y’: -3.656875, ‘Z’: -3.050625, ‘Red’: 242, ‘Green’: 242, ‘Blue’: 242} Based on this I’d expect to see the red property unless it’s getting transformed in the API itself. Also, can you expand on converting a color value to between 0 and 1. There is no information on how that’d be done in the link you provided. ---

@omar Any thoughts on how this would be done? ---

For converting values from 0 to 255 to 0 to 1, you can reference this post: > This post might help with the `Red` attribute not found issue: > [@Per point attributes in cesiumjs](https://community.cesium.com/t/per-point-attributes-in-cesiumjs/7795/8): > > If you check the first part of your .pnts file (either with head or with your browser's dev tools) you can see something like: "pntsè,ì€+X{"BATCH\_ID":{"byteOffset":..." which indicates that each point has a BATCH ID. Now if you look at the Batch Table of your file, (which in the case of this file that was made with the point-cloud-tiler binary is at the very end) you will find this string: '{"Classification":{"byteOffset":0,"componentType":"UNSIGNED\_BYTE","type":"SCALAR"}}'. Unfortunately it do… It might just be that you need to use !== instead of != for the comparison. Were there any errors that were shown in the console? ---

I’m getting no errors in the console and I’ve tried the following with no success. “{Red} !== 242" "{Color}.Red !== 242” “{Red} != 242" "{Color}.Red != 242” “{Red} !== .949" "{Color}.Red !== .949” “{Red} != .949" "{Color}.Red != .949” “{Color}.Red != 242" "{Red} !== ‘F2’” “{Color}.Red !=='F2'" "{Red} != ‘F2’” “${Color}.Red != ‘F2’” Is turning point display on and off with a Lidar based 3DTileset based on color something that’s been tested and known to work? ---

@dzung I’ve applied this example to ion asset id 168554 and it doesn’t seem to work. Would you be able to look at that asset and see why it isn’t? The color I’m trying to turn off should be 242,242,242. ---

Yeah, somehow I must have made a mistake when implementing because when I tried building the sandcastle example it worked fine. Appreciate the help!
