I create a BufferGeometry and set its attributes like so: this.clearGroups(); this.addGroup(groupStart, groupCount, 0); const indexAttribute = new BufferAttribute(new Uint32Array(indices), 1); this.setIndex(indexAttribute); const positionAttribute = new Buffe…

[image] xortdsc: Now occasionally I recall this setup code if the number of vertices changes. It is not intended to overwrite existing attributes with different sizes. Call dispose() on the old geometry and then create a new one. Ideally, you avoid all of this and create a geometry with suff…

Okay. Do you see a problem with the workaround of removing the attributes before re-setting them as stated in the workaround ? This way I could handle everything inside the custom geometry class and the user of that class doesn’t need to worry about recreating it under certain conditions.
