When signals are transmitted between the models running at different rates, no AI or AA filters are automatically applied. We need to fix our models.
|
This is known, but we just haven't fully groked it yet. We need to look closely at every place we have IPCs between models running at different rates. The sender has no information about receivers, so it can't reasonably do anything to pre-filter the signal on it's own.
So for transmission from:
- faster -> slower models: add anti-aliasing on the sender side
- slower -> faster models: add anti-imaging on the receiver side

*sigh* This is one of those things that I meant to take care of months ago, but haven't yet. I agree that it needs doing. It's been on my whiteboard to-do list for a long time now. Bad Jenne for not taking care of it. |
