Hi Ajver. I forget exactly what I told you now. See if this helps. It's a typical animated prop for Engine 1 as used on my own designs. They work well in CFS2 & FS2002.
The prop actually consists of only 2 different basic parts but each is duplicated making a total of 4 separate parts to give the full animated effect. I've moved them apart on the Z axis so you can see it more clearly.
prop0_blurred is a transparent disk with transparent texture applied to the front.
prop0_still is the 3D 4 bladed prop, visible when the engine is off.
prop0_slow is a duplicate copy of prop0_still with a different part name.
prop0_blurred.1 is a duplicate copy of prop0_blurred with flipped polys.
I've selected View/View Surface Normals so you can see the direction the polys are facing on the transparent disks.
The prop disks are simple 2D parts which can be viewed from one side only so the polys on prop0_blurred.1 are flipped to display from rear views.
(The transparent texture is applied to the front only of both disks & the texure assignment is not changed for the rear view. This is a lttle Hagar trick which looks good in the sim.)
The part names are important & selected from the "aircraft stock animation" part names list in FSDS2 Part Properties.
You can create your own transparent prop texture or use an existing one. These do not always look as you might expect. It would be a good idea to check out some you particularly like from existing designs to see how it's done. I must admit to "borrowing" other designers textures from time to time, with full permission & credit of course.
