First time in blender HELP!!!

[harrisjosh2711]

Playing around making my first model in blender. Can anyone tell me why half my model looks as if it is cast in a dark shadow?

It did not look that way until I put the texture on it. I assume I'm making a mistake somewhere.

Hi from what i can see the cylinder is simply showing the gradients of color seen on the texture sheet. Usually in KSP strong gradients are avoided as they tend to make the light behave oddly,  highlights and shadows where there should not be any.

Thanks! ill pick out some different textures and see how that goes for me.

Parts that I hand painted white are still showing up black????? This is getting frustrating!!!!

Looks like you might have a light in your scene? Try deleting it or switching to shadeless display:

That fixed the problem. I appreciate the quick reply.

@harrisjosh2711 I am in the same position you were, newbie to blender, unity etc. I can make my cube in blender with meters as the units, export it to FBX (though I understand now I could do it via .blend) the scale of the object shows as 100 in Unity 5.4, I add a mesh collider with convex selected and add part tools, I then gave it a modified stock station hub cfg, but when I add it in the VAB it is miniscule, I need to rescale it by 100 for it to be normal size. I am missing some simple elementary step, are you able to help me, since you have done the same journey recently?

Edit: OK, it was some weirdness in .fbx export, using the .blend instead fixed it, now I just have to figure out why it is upside down.

@selfish_meme Can you please post a Unity screenshot? By default, if you import a .blend, it will be rotated -90 degrees on x. Have you tried dragging it in to the editor or have you done otherwise?

I know about the 90', but this is 180' in the SPH, I tried fixing it by dragging it into an empty GameObject as the Unity doco suggested, here's the Unity screenshot

Here it is inside the SPH, I turned on the CoM and CoL indicators

I have been trying to figure out how to orient a part with a lifting surface for a minute now. No matter what I have tried its been off. Let me know if you make any progress. Here Is a form I posted on no one has replied to. 

 

[selfish_meme]

@harrisjosh2711 I was going to go back to this thread I found, in the future, once I got it imported, it has a lot about setting CoM, CoL and CoP

@SpannerMonkey(smce) you commented a lot in the thread I mentioned in the comment above this one, have you got any ideas why the part is upside down, or at least how to orient the lift from a part?

Hi, not operating at full capacity but i'll take a guess

Regarding the parent orientation, if the image posted yesterday is correct then the orientation is wrong for  SPH and that matter VAB  .For correct alignment i always align Y up, pretty much everything goes this way around (only stock, mod parts can require other orientations)  and ensures that the part will place correctly in both assembly areas

Spoiler

main game object note rotation 0 0 0

 

Models rotation,  it never used to matter that much , BUT , since 1.3.1 we've seen some oddities appear if the models base rotations and scales are not set to zero and 1  as below  ( oddities like control position inversion etc)

Wings are odd things, but you can add a lifting module to pretty much anything that's correctly aligned and have it generate lift ,  as you're creating a lifting body following the alignment above will let it work.  For wings there are required rotations however, as illustrated below

Spoiler

KSP wing game object rotation .  At pos zero, scale1,  rotation 0 0 0

The actual wing model pivot has to have the following rotation 

 

I'd advise sorting all the rotations and scales  before you get to unity, and get in the habit of doing that way  , it'll pay off later on. 

Cant help with the blender side of things as i only use it for grabbing example objects

hope that helps a bit

[selfish_meme]

Thank you very much for this reply, I experimented a bit with rotation in Blender and I think I have it, Hope you feel better.

I ran across the dreaded 255 polygon model limit in Unity (thanks again @SpannerMonkey(smce), I found an old thread where you explained that), so I figured out how to decimate the polygons in blender to create a low poly model and then add that model to the high poly model and add the mesh collider to the low poly model in Unity. Finally seem to be getting somewhere, symmetry is off somehow, but I think I will be able to figure it out.
