Question by SVKsuli · Dec 26, 2020 at 01:32 PM · blenderrendererbounds

Wrong positions from bounds

Hello, i have problem with Renderer.bounds positions of imported object from blender. I have script that create box around selected object/objects depend of their min/max bounds.


When i test it on prefab objects from unity then it work. alt text


But when i try objects from blender then it works only sometimes. alt text


  • Both objects have only one mesh. Object on left is correct, but object on right have box like 50% bigger.

  • Both are made exactly same, difference is just a bit in visual. When i check the values from Renderer.bounds of that wrong object then values was already there wrong.

  • I tried create two sphere prefabs and placed them in position from bounds and there was exactly on corners of that created box.


  • Know somebody what can cause this ?

  • is there way how to avoid this ?

  • if its necessary i can share whole code how i creating that box. Thx for any help.

Well, the bounding box is always axis aligned. Renderer,bounds essentially represents the AABB of the mesh's local bounding box. See my answer and the comments below my answer.

You are right, problem is in object rotation but it dont look like it because model is created in rotated Z axis so it look like its not rotated so it mess up my code.
