Need some updated info on texture map with Ksp 1.1.3

[Warsoul]

I need to know wich map exactly Ksp support for his shader for better visual result with Substance Painter 2 and Designer 5.

Base Color/Albedoe,Height,Roughness,Metallic,Normal,Ambient Occlusion,Emissive,Diffuse,Opacity,Specular,Glossiness,Reflection,Displacement,Etc

Unity 5 use PBR, how we can use PBR in Ksp if we can.

How many polygons for each models and collision mesh. My collision mesh can be multiple collision box ?

How i can use Rescale Factor on X/y/z only ?

How i can use dynamic material in Ksp ?

I searched on forums but they look outdated for Unity 5.3

You'll find varying answers on this, I've been advised that even around 10k shouldn't affect performance much, but I've rarely pushed anywhere close to that. The real performance hit is the physics, so you should keep your colliders as low poly as absolutely possible or even use Unity's primitive colliders if you can. Yes, you can have multiple collider meshes.

Instead of:

mesh = model.mu
rescaleFactor = x

Use:

MODEL
    {
        model = yourmoddirectory/model
        scale = x,y,z
    }

Unlike using rescaleFactor, you will need to manually adjust the attachment node locations in the config when scaling in this manner.

Dunno about the rest, hopefully someone can answer them for you.

Model polycount is apparently not an issue at all, although that's no reason to be excessive if you can use multiple primitive colliders instead of a mesh collider do that - also remember mesh colliders can't be higher than 255 tris ( or polys? I forget ) and have to be convex.

Shaders are usually still diffuse+specular/opacity with a seperate normal map - PBR isn't officially supported yet, there is a mod around to config & load a PBR shader. Writing your own is fairly trivial. AO would be a layer in your diffuse map, the rest aren't supported as maps unless you write your own shader.

KSP is unity 5.2.

[Warsoul]

How i integrate my sketchfab models into ksp forum ?

AO will be the alpha channel of the Diffuse map ?

Ksp Shader = R=Diffuse G= Specular B=Opacity A=AO ? + Normal map Grayscale 16bit ?

[Van Disaster]

What's in the alpha channel depends on the shader - usually Specular, each shader will tell you what's where in the Unity inspector. For KSP/Specular it's RGB diffuse, A specular. KSP/Bumped Specular is the same, with a seperate bumpmap ( not a displacement/height map ).

To integrate AO map into that, load your RGB diffuse into a paint package & put the AO map in as a layer on top of it, blendmode Multiply ( or Overlay, whatever looks better when you've finished tweaking ) and use the combined result. Well, that's the traditional way using baked AO maps from say, Max, I don't know anything about Sketchfab or the minutae of it's terminology.

Normal maps I'm not sure about now - I try not to use them, the one time I did I exported one of the blue ones directly from PS as I'm used to for other things, but apparently Unity does something itself. I'd rather spend polys on detail & not have the drawcall for the extra map, but that is a bit mad for rough surfaces.

Thank you; thats an clear answer. Too bad Ksp don't use height map and PBR.

RGB = Diffuse+AO(Blended) A=Specular

Bump Map instead of Normal Map

Bump Map 8bit grayscale ?

Can't find any tuto for addind fairing to my engines.

Don't use spaces, and don't use .mu

model = MaErDa/AtlanderSupersize/model

No idea about fairings, I suspect it's a named gameobject with a specific layer. You could try using the KSP PBR shader, I don't think it's officially supported but it's in the Parttools distribution already. I haven't tried it myself.

Can't find your Ksp PBR in my Parttools. I think i have the last Parttools version.

@Warsoul As far as PBRs go right now, there is this thread (seems VERY experimental, though):

last I heard, PBR had been pushed back to 1.2, which is the next update that we are getting. Should be out within a month or two.

Hi sounds to me like you'd be better off taking a look at a couple of part modelling for ksp tutorials, than just picking random advice.  Although the the game itself has moved on to a new version of unity most of the old part modelling tutorials with the exception of wheels and landing legs, are still current and still valid.

There is no need to use a matching version of unity to process your parts, unless for some reason you want to use the new asset bundle format ( which converts the parts and scripts into a machine readable package instead of the normal .mu and associated textures)

I'm sure I'm not the only modder who converted projects to unity 5 and then wished they hadn't.  It's probably easier if you're just starting out as you wont know how easy animations and heat/emissive animations were to do in unity 4,2,2 compared with the convoluted U5 onward methods.

It's considered good practice to carry out all your scaling in unity than through the cfg and it's very rare to find anything scaled as you intend (there was for a long time a scaling bug with the model node)

I'm in no way inferring that you are new to modelling or texturing, but a couple of good tutorials are easily capable of saving hours of wasted time, and will give a good grounding in the basic procedure for unity etc. The tutorial below is generally considered  to be one of the best and many popular modders have used it as a first step.

 

[Van Disaster]

Yeah, the KSP PBR shader I have seems very much a WIP, given it's got a fair bit commented out :p.

[martinezfg11]

I do most of my texturing in Painter 2. I just use the Unity4 Diffuse option when exporting, which creates a spec map from the roughness/metallic values and puts it in the Alpha channel; then convert to DDS once texturing has been finalized. Other maps such as normal and emissive can be used without issues.

[Warsoul]

PBR is supported with the 1.2 patch ?
