Prop-Behind-Cloud syndrome

Here's a pic of Stuart Green's beautiful Mitsubishi G4M "Type-1 Lighter" in FSX. I've tried swapping out the prop texture with several that I know fixed this problem with other FS9 ports, but none have any effect here. And this one looks different that others I've seen. Usually it's just the prop blades that disappear behind clouds. In this case it's the entire prop disk that occludes clouds and trees. This is probably a feature of the model and can't be fixed, I'm guessing...

 
I think this is a different problem Paul. The prop model itself is excluding clouds and probably autogen too. I've not found a solution for this problem. With most prop port-overs darkening the alpha will make the prop blur almost invisible, so it doesn't show in a cloud scape.

That's what I was thinking too, but wanted confirmation before I gave up on it. I tried converting the model using Model Converter X, with expected results (virtual Betty Bits all over the desk...) :)

 
This is most likely a Z-Buffer setting in the actual prop model. The Z-Buffer setting is not making the determination that the prop is either in front or behind the cloud. This can only be fixed in the model itself.

I'm seeing this in some airplanes in P3D. Possibly something for developers to be aware of and take into consideration with new models. Old models would require a patch to fix this.

Be great to see and FsX Native Betty though!

Hello,
I agree with gman....from what I've read FS9 and FSX use totally different builds for the propdisk. I have the same issues with "Shupsters" A-26, F7F portovers. I have, however, just flown an early gun nose model of Milton's A-26, texture.stinky, if I recall correctly, and after patching some textures for it, for some odd reason the propspin was showing correctly with the cloud and autogen background. I'm not quite sure what happened there or if it was a permanant fix. But I was noticing that there was no invisible prop with cloud background, since this is a "peev" of mine also!!!!! Once I climb back into the A-26 to take her for another spin, I will take a screen shot if the effect is still correct and post it here. Cheers!!!!!
 
I've also messed with these with Kazunori Ito's models. With his it is the prop disc in the model that isn't coded to show transparency. It's correct for the model, but when moved into FSX or P3D, transparencies are handled differently and thus the "clouds and autogen" issue. You would need the source code in order to correct it.

In our library there are FsX native versions of the A-26.
 
Has anybody tested this FS9 model in P3Dv2 ?
If I'm not mistaken, the "regular" FS9 models that used to suffer from "props behind the clouds" problems in FSX are in fact showing CORRECTLY in P3Dv2. They even get self shadows and virtual cockpit shadows :)
So I'm wondering if this specific problem "props in front of the clouds" would be solved as well ?
 
I think i've got the right one.. Its Stuart Green's converted to fs2004/fsx from CS3 I think.. Just woke up.. sorry.. Program is P3Dv2 and i went straight from zip to running..

Fantastic Pam! Even cockpit shadows....well Paul that's your answer...get p3D v2:wavey:
 
Thanks Roger..
And not meaning too open old wounds but P3D is a development platform only. it isnt made to be enjoyed. You have to be a developer.. However, according to Lockheeds license agreement which I post here..

Anyone can work on becoming a Prepar3D® Developer. No matter if you are a seasoned developer, or just starting out, we want to encourage you to develop for Prepar3D.

Anyone

So get on out there and ""develop"" :;chuckles::
 
But, Pam said: "... Its Stuart Green's converted to fs2004/fsx from ..." Did somebody do a conversion of this plane for FSX? I need to find that one first. That would be good news!

EDIT: Well I found one on fs-freeware.net that claims to be a an FSX conversion, but the "prop disk occlusion of clouds and trees" was not fixed. I could live with the props behind clouds, but the whole disk standing out like that makes it a "non-player". Guess I have to get P3D!

Thanks Pam! That's the one I found too (see edit prom previous post).
 
Yep I just tried it too with the same prop issue and I think it may have been gauges that were fixed. Interestingly in Dx10 it was almost totally transparent and I used the Dx10 fixer tool box and converted the 8bit textures so now I could see the aircraft but the prop issue wasn't solved.
