Error: Not filled all elements of the vertex

Doesn't happen every time.
Strangely, this mostly happens when shaders are not enabled.

I propose that this mod is worked so that it does not do anything at all, unless a shader is enabled.

Can confirm, suffering the same crashes. I was able to reproduce this :

• without any shader enabled
• both on Fabric (with Iris) and Forge (with Oculus)

Here's some crash reports :

• fabric-crash-report.txt
• forge-crash-report.txt

If necessary, i can provide reports from other players on the server i'm playing with.

Hope this helps!

Same for me on forge 1.20.1 with this mod and like foxy's, mostly happens when shaders are off.

It also seems to happen when I change a deployer's mode.

Here's a crash report from me:
crash-2024-06-16_22.09.08-client.txt

Hope this helps!

fabric 1.20.1
crash-2024-06-22_16.53.32-client.txt
Hope this helps

Can confirm
Fabric 1.20.1, only crashing when shaders are disabled.
crash-2024-06-29_16.56.41-client.txt

Any one try this?
Delete this line,

Still crash
Not having crashing issue for 1 hour.

This is a real problem, added this to my modpack and now I have tons of crash reports all related to this problem. This is very urgent.

Can you make a PR so the author publish the fix?

@Rodrigo816
Its just avoiding crashings instead of fixing the actual problem, so..
