• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

MSFS20 Propeller Animation in Blender

Hi all,

I'm having some trouble animating a propeller in Blender. I've successfully animated all of my control surfaces (tested in sim), and tried the same approach to animating the blurred propeller, using the Cessna 152's .xml file as my template. Unlike the control surface animations, the propeller code has a bunch of nodes which leave me absolutely befuddled! At first, I thought they were just object names, so I tried replacing each value with the object name of my blurred prop (just to see if it worked) and changing the ANIM_NAME appropriately, but that doesn't appear to work, as shown in the in-game screen-grab attached. The prop spins at ~1200-1500 rpm (unless I fudged the ratio in the .cfg, in which case ~3000), so it should be visible, right? Even when static in the hangar, nothing appears. I'm using Blender 2.90.1. Any ideas?

Thank you!

Best way is to have a single empty as the root object for ALL of the propx_still/slow/blurred and animate that. This becomes your ANIM_NODE_ID entry.
Then the other nodes control the visibility: STILL_NODE_ID etc
 
Thank you, that worked perfectly! And showed me another issue...if I may ask, what shader is used for the blurred prop? I have the albedo map from the default Cessna 152 mapped onto a low-poly rather lentil-shaped mesh. It appears with transparency (though no gradation) just fine in Blender, but shows up as an opaque disk, albedo applied, in the sim! I'm using the MSFS Standard shader under the Material Params in Blender. I can only imagine I'm missing something dumb, but I just can't figure out what.

Make sure you have the Render Parameters in the MSFS Material Params set to: Alpha Mode: Blend

Yep, have Alpha Mode set to Blend. I even tried it with a new texture, just a transparent 1024x1024px square from GIMP. Still just a white circle. Here are my rendering settings, and the shader (should be as-generated, but maybe I'm missing something?).

Yea I can see immediately that the graph has not connected the Alpha. Recommend recreating the material OR change the alpha to Opaque and then back to Blend. Will try send a screenshot of what it SHOULD look like later.
