Issue with proxy: AO shines through main body

[x3kj 1247]

I've got an issue with one of my tanks. I exceeded maximum vertex count, therefore i have to use a proxy. So i made a proxy of the hull, the rest is in the main.p3d

The problem is that the AO of the proxied parts shines through the main body. I tried changing the location of the shadow LOD so far (put the shadow of the hull into main.p3d and back again) but that doesn't change anything.

Does anybody have any clues what could fix this?

This may (or may not) help.

it's only the proxy that is behaving like this (shining through) - all other parts behave correctly.

I used a _ca texture (DXT5 with alpha) and have this issue - the names are correct pre conversion. I also tried a _co texture (DXT1 with alpha) - this "solves the issue" of shining through. BUT it is only a 1 bit alpha, making the tracks look very janky, which is not what i want.

This is why you should always map parts that need to use an alpha (such as your tracks) to a separate texture panel rather than including them on the main body textures. I.e. use _co for the main body and have a separate _ca for the tracks.

 

See BIS vehicles: Tanks, tracked APCs etc. have their track mapped to their own 512*512 _ca.paa (e.g. armor_f_beta\apc_tracked_01\data\mbt_01_track_co.paa) and main hull, turret etc. textures are 2048*2048 _co.paa.

 

Likewise; car, aircraft, house etc. windows are mapped on to an extra _ca.paa, weapon optics lenses are are mapped to an extra _ca.paa and so on and so on.

The tracks ARE a seperate texture. It's not the first time i do this. But the first time to require a major part of the hull to be proxied away.
When i move stuff from main.p3d to proxy, those parts will shine through, despite having standard _co textures without alpha (before and after conversion). And vice versa-> from proxy to main.p3d, those parts won't shine through anymore.
 

 

have a separate _ca for the tracks

The current A3 models have _co textures with alpha for the tracks (DXT1 with 1 bit alpha).

Right, sorry - I read this bit wrong:

It sounded very much like you were using one texture for the hull and the track

TBH that's how I read it too.
