LogText creates ArgumentException because of too high vertex count

[Jens-roesing]

Hello really like this console.

I found a Issue for too long Log-Texts, the long texts create too many vertices for the text mesh.

Error-Message:

ArgumentException: Mesh can not have more than 65000 vertices
UnityEngine.UI.VertexHelper.FillMesh (UnityEngine.Mesh mesh) (at Library/PackageCache/com.unity.ugui@1.0.0/Runtime/UI/Core/Utility/VertexHelper.cs:226)

UnityEngine.Canvas:SendWillRenderCanvases()

The Error is thrown by the LogText Object multiple times

This also creates a Memory Problem. about 60MB is used for the UIVertex Meshes that the console creates. The Memory snapshot comes directly from a iOS Development Build.

Hm, if I recall correctly it's supposed to split up into multiple text components if the logged string is large enough. Haven't worked on this for a while 😅 You may be able to manually lower that string length limit in the source code so that the vertex limit isn't reached.

One day I want to rewrite this whole asset... There's a lot of things I would do differently... One day...
Glad you like it :) I use it in my projects too.

Yes, normally it's splitting then up, but in my case this error happened on loading a scene. At the beginning of the Scene, many async operations are executed, and it's really laggy in this loading time. Maybe that makes a problem for the Splitting.

However, I solved this Issue for me, I am now more carefully, enabling the console a little later and clearing it more often helped.
