splat disappear issue

[pradeepnandigam]

Hi @mkkellogg ,

First of all, I want to express my appreciation for your fantastic work on this repository. The results have been great overall, but I am encountering a minor issue while trying to change the color of the splat. This issue does not occur consistently, so I wanted to describe it in detail.

I am working on the delta feature, which represents changes, and I use colors to indicate these changes. For example, when I navigate to a particular spot, the delta is highlighted in green. Initially, the color changes work well for the first two or three locations, and I can clearly see the delta representation. However, after these initial changes, the splat starts losing its properties, and the color change no longer appears as expected.

I have attached images to demonstrate the issue:

Images 1 and 2 show the proper color change for the first two locations.
Image 3 illustrates the problem where the splat becomes less visible or does not display the intended behavior.
This issue happens consistently after the first two or three color changes. Could you please look into this? Any guidance or suggestions to resolve

**Code snippet , I am using to change color is **

this._gViewer.splatMesh.splatDataTextures.baseData.colors = updatedColorData;

this._gViewer.splatMesh.splatDataTextures.baseData.needsUpdate = true;

const toCount=this._gViewer.splatMesh.getSplatCount(false);

 this._gViewer.splatMesh.updateDataTexturesFromBaseData(0,toCount-1);

Image 1: (location 1)...........................worked well

Image 2 :(location 2)............................worked well

Image 3: (This is the issue)

@mkkellogg, one more thing I observed is that if the changes are made at the same location multiple times , it works fine. However, the issue occurs when the location is changed simply when camera is moved to another location, and the color is updated

should i call any other function to update the data?
