Hi.
In our game we use time dependence in materials. This means, that instead of using “Time” node directly, we store the time value in MPC (Material Parameter Collection) and use it in the materials. The issue is that by doing it the WPO based animation, it gets instantly blurry when used with a TSR or TAA anti-aliasing. I know, that it is probably due to the motion vectors being incorrect. but I have no idea what can be done. If any of you knows more about those issues and how I can fix it, please help.
Thanks.
The “previous frame switch” node was designed to solve this problem. You will need to store both the current value for the MPC, and the previous value. Access them both in the material and input them into the previous frame switch node before passing it into WPO. This will enable the engine to calculate a velocity value between the two frames for use with temporal effects like AA and motion blur.

Hello BananableOffense, thank you so much for your answer.
I will try to figure it out in the next few days and will come back here with the results.
Have a nice weekend!
The “previous frame switch” node worked flawlessly. The smear is gone and temporal effects are all OK!
