Godot Version
I am using the latest version of Godot 4.7.2.
Question
Hello, this is my first time posting on this forum. I’ve spent several hours trying to solve this problem with GPT, but I still haven’t been able to fix it, so I’m asking here. I used GPT to translate this into English, so please excuse any awkward wording.
- What I wanted to do
I simply wanted to create a box mesh using a MultiMeshInstance3D node.
- The problem
As shown in the image below, the MultiMesh does not appear at all.
There is one strange thing, though. If I adjust the Custom AABB values under the MultiMesh section in the Inspector, a strangely distorted box mesh appears, as shown below.
After that, changing the Custom AABB values again does not change the shape shown in the image.
Oddly enough, if I change Material → Albedo while it is in this state, the mesh becomes colorful.
Below is what happens when I set the Instance Count to 2.
In other words, when I create two box meshes, they appear like this.
Every time I increase the Instance Count, another one of those blade-like shapes is added.
- It’s hard to believe that such a simple but serious problem is happening only to me…
However, I couldn’t find anyone with the same issue even after searching the web.
I’m fairly new to Godot, so I suppose it’s quite possible that I’m doing something wrong. However, as far as I can tell, I’m following the correct procedure.
I also tested this with previous versions of Godot.
4.6.3 — Same behavior as 4.7.2, including the strange behavior when modifying Custom AABB.
4.5.2 — Same overall behavior, although the shape that appears when modifying Custom AABB is slightly different. In this version, it appears as a straight pillar.
GPT keeps telling me to run more tests. However, even after pasting and trying various scripts that GPT provided, the box mesh still does not appear.
I’m exhausted. I feel like Sisyphus at this point.
Does anyone have any idea what might be causing this?
For reference, I am using an RTX 4070 and 16 GB of RAM.
