Sprite to world coordinates weirdness

[cedar chasm]

Okay so. For some reason things are not lining up where they should be.

My blender setup uses a 45 degree tilted camera pointed at the subject. Between this is a 3200*3200mm plane (scale is needed to get the coords to translate properly, doesn't matter at all for this).

Using a shrinkmap modifier, I can pinpoint verticies on my 3D model, and have them "stick" onto the plane; this results in what should be a pixel-perfect projection of where that vertex is on the sprite.

But it's not. For some reason the coordinates in game do not match and I can't figure out why. Below shows the problem:

Fig 1: My blender setup shows these coords for the turret

Fig 2: Vehicle position is 0,0 in the world

Fig 3: Turret position set to my blender coordinates

Fig 4: Sanity check with my "print cursor coords" item

To prove that things should be lining up. I aligned a screenshot from in game to my blender scene. Kind of hard to show via pictures but the vehicle sprite is basically dead on.

So if my rendered sprite matches my 3D model, then my vertex positions should also.....no? If so where's this difference coming from?

Okay I've figured out the how, but not the why.

My turret scale was set to 0.8. Multiplying my hardcoded coords by 0.8 aligns everything properly.

I have no clue why this is though, as far as I can tell entities are origined at their own center, scale shouldn't affect anything?

Entities are origined at their center, but if the sprite image's center isn't aligned with the entitiy center, that could also be the cause

Btw, entities usually have a scale of 0.5 and a resolution of 64 pixels per tile. You can use whatever you want, but that's the standard and can be good to follow

Atm all my sprite are 1.0 scale bar the turret, I'll rescale everything properly for LR/HR when I've got all the "basics" done

The turret sprite should be central to its entity 0,0. Everything I can check seems to confirm this apart from this one weird issue.

I've got the rocket bays on top to do next, I'll see how they look

[strange jolt]

You shouldn't need to (and can't) specify for low resolution and high resilution separately, the game downscales sprites automatically

[cedar chasm]

Isn't the norm that LR is 1.0, and HR 0.5?

[strange jolt]

There is no concept of LR and HR at all since factorio 2.0. Its all in high resolution, and at a scale of 0.5.

Oh apologies I'm back at 1.10

Probably should have started with that
