I am working on a large model and would like to mirror one side of the model to the other side by using instances.
When I create an instance and set the Z axis scaling of the instance to -1 I get the result I need, however it results in an additional draw call which I would like to avoid to improve performance.
I found out that the extra draw call is caused by using a different scaling for the instance than for the source mesh. Changing the position of the instance on the other hand does not result in an extra draw call.
I also tried to attach my instance to a new TransformNode and to only scale the TransformNode instead of the instance. However this also caused another draw call.
Do you have a suggestion how I can mirror/ scale an instance without causing a new draw call?
