This mod adds animated "piston arms" to Thermal Expansion dynamos, similar to BuildCraft engines. It uses a smooth animation, a lot like the old RedPower2 Blulectric engines.

It uses no reflection, ASM, or other trickery. Thermal Expansion doesn't register a special renderer of it's own, so this mod just adds one.

This mod is optional on the server-side, but if it is only installed on the client, you will have to open a dynamo's GUI for its animation speed to update. If you install the mod on the server-side as well, the RF/t will be automatically synced to keep the animation speed up-to-date.

Yes, you can use this in modpacks. The MIT license grants unlimited redistribution.
