The engine rotation animation of the ini350 seems to be much slower than that of the actual device.Here I have cited two links to illustrate this issue.

Airbus A350-900 (Trent XWB) engine start

This is an engine startup video captured from the actual device. Please pay attention to the speed of the engine rotation animation.

And the second link is the engine startup rotation animation of inibuilds350.It can be seen that the engine rotation animation of the ini350 is much slower compared to the actual device.

(GREAT ENGINE SOUND!) Lufthansa A350-900 Takeoff from Frankfurt

At the same time, the second question arose. This link is the engine take-off perspective of the Reality 350.It's still the same problem - the engine rotation animation is too slow.

Can you improve it ?

I'm very sorry, sir. After communicating with you last night, I realized that the problem was not with the engine blades. The real issue was with the rotation animation speed of the cone. The speed here is really slow. You can carefully look at the link I referred to. The cone rotates very fast in the Trent model, while in the Inibuilds A350 model, the rotation speed of the cone is very slow. Moreover, the cone rotation speed in the old version v1.11 ini350 is also very fast. So, there is indeed a problem.
