Hi everyone I have 4000 cubes, and I have built them with the aid of the json file, then I put them as a child of one Box, to rotate whole of my structure. the Box is in the (0,0,0) point, and the other cubes are in near of (8000,6000,300) point, the problem is when I rotate the box , the other cu…

You did not update the right mesh in your orientateX / orientateY methods. Contrary to what I said, the position of the dummy mesh should be (0,0,0), only the pivot point matrix should be set to the big value: https://www.babylonjs-playground.com/#ZEZLAT#8

the problem is I want to know how can I rotate the structure (which has include 4000 cubes) like a single mesh?

Set the pilot at (8000,6000,300) and its pivot point to the same value: https://www.babylonjs-playground.com/#7DVSRP#3

should i write pilot instead of parent in the code?

I didn’t reuse the cylinder you named pilot, I created a TransformNode instead that I named “parent”. You can use the “pilot” mesh instead of my TransformNode if you want, just replace all occurrences of my “parent” variable by “pilot”.

sorry for taking your precious time again, should I set parent at exact point of 4000 cubes center?

You should set it at the center of rotation you want for the 4000 cubes as a whole. Given your description, it seems it is (8000,6000,300) but I may have misunderstood what you said.

i have a json file which has X,Y,Z and size of 4000 cubes, I fetched the json file and built cubes with the for loop, this part of my code: //**************Fetch Cubes **********/ // cube factory and transition color const color1 = new BABYLON.Color3(0, 0, 1); const color2 = new BABYLON.Color3…

i did above code, but the structure goes out of camera view.

Please, make it work in a PG ( https://playground.babylonjs.com ), it will be easier for everyone to see what’s going on. Note that you can put your json in the PG, even if it is several MBytes.
