MSFS20 Model exported glitches

[Socorrista22198]

Hi all,

In blender I see the model OK: (don't worry, it will be a mirrored UV)

But after compile it in MSFS I see it like a hippie version:

The glitched areas are wing and tail. I found the problem is when I add new materials, once compiled in MSFS the color change. The first material for main fuselage, Generic_LOD5, looks OK. The others materials, wing and tail, are copies from Generic_LOD5, they are exactly with the same parameters. but they look glitched.

Why could this be happening?

(I've tried the exportation with the latest Asobo and Flybywire plugins with the same result)

I just discover that the problem aren't the copied materials, the problem is the position on the list of materials in Blender :S The material positioned at first position looks OK, the others no. Some ideas?

Cheers

Hi,
Usually only one material is applied to a part. But from what I can see, you have 3 materials on the object, hence the problems.
It is possible to split your object in several elements: fuselage, right wing, left wing, tail, stabilizer ... and apply only one material (or one set of textures) to each element

Upsss I didn't know that, thank you! I will try

(or one set of textures)

Is it possible to apply several textures to only one material? I mean, if now I have three material with one texture each one, would be nice to have only one material with three different textures.

I think I see what you means: three textures distribued on one "file/texture" and the UV are distribued on this texture.
But in my opinion, it is better to create one material for each element/objet: it is more easy to realize that you have in mind.

PS: a material normally consists of one (albedo) or more textures (albedo, comp, normal, emissive ...) and parameters (metalic level, roughness level, etc) applied on this texture

Instead of using multiple textures. you might consider combining the textures and reworking the UV mapping. MCX has a feature to optimize drawcalls that can do this. I'm not sure if there is a addon for Blender to do this.

Oh yeah it works!! I'm reading the SDK little by little and didn't found that rule... Is it at the SDK documentation? I think i need to start reading a totally noob MSFS 3D creation documentation xD.
I never would have figure out that rule, because imported models from Asobo to Blender, have several materials per object, I thought I could do the same to optimize a little bit more the model like the original:

Yeah, that's what I have in mind for the "livery creators" versión of this fix. I´m trying to fix the c152 LODs to avoid missing liveries from parked aircrafts while I'm taxing. One version will be for users, the model will automatically load the default liveries textures. And other version more optimized for creators, only one texture with all the other textures combined.

Thanks for all! Cheers

Hi,

Remember this: do not confuse material and texture.
Combining several "textures" (i.e. material) is not easy because if this material has an albedo, a comp and a normal, you will have to combine these three "textures" as well
