Well, this is exactly what I'm trying to do, replace baked piston animations with restricted procedural one, but LookAt refuses to work... Or I didn't understood you. =)
According to the workshop importer in game its 1,500 for the plague ward with a 256x256. They're under the ability replacement button rather than the general workshop item button.
Good choice to replace the middle part. Now, the new sinkhole makes for a much better focus point of the scene. And I like the colors in the scene overall. Cheers!
Yeah modo and C4D have pretty solid set of modeling tools. And houdini is a good replacement for Maya for rigging and animation, sidefx has good pricing options
Turn off isoline display. I wrote a little script that replaces export/export selected. It just turns off isoline and then exports. simple but a life saver.
