I use this simple code to draw a line: if (lineUniqueID == null) { lineDirection = BABYLON.MeshBuilder.CreateLines(“lines”, {points: myLinePoints, updatable: true}, scene); lineDirection.color = BABYLON.Color3.Red(); lineUniqueID = lineDirection.uniqueId; } else { lineDirection = BABYLON.Mesh…

Maybe is the same problem/solution from here [image] Drawing lines for debugging positions Questions It seems the bouding infos are not refreshed when updating a LineBuilder. Corrected playground: https://www.babylonjs-playground.com/#75U928#1

Are you able to setup a repro PG for this one? Else we can’t do much.

Project is too large for PG :frowning: I must looking for a bug…

Described playground does not work but thanks - I’ll try it.

Oh, then check line90. this was the trick

“refreshBoundingInfo” is really solution of my problem. How this function really works? In help is one sentence about it.

I think if ‘CreateLines’ has updatable property set to true then the bounding box info of the shape is automatically refreshed, if not, you have to tell him to update the bounding box, using this function. And, I hope to not be wrong, the boundingInfo is used in the culling system

[image] MarianG: the boundingInfo is used in the culling system Correct (if alwaysSelectAsActiveMesh= false, which is the default);

Line is not visible under some angle of view
