LOD index/mesh not changing with SetLOD() #46

Closed Panicat closed 2 years ago

Panicat commented 2 years ago

It stays on the highest resolution. I think I understand how the code generally works for this, selecting an LOD mesh from an array with LOD meshes.

Below, you can see that 3 meshes are in fact generated and put into the array:

SetLOD() with index 0, 1, or 2, appears to refresh the mesh in game as it disappears for a very brief moment but it's still at the highest resolution, which is LOD index 0.

The active LOD never changes. I did try to change the SetLOD() function a bit so that it is FORCED to change the active LOD but still seems like it doesn't change:

The SetLOD() function to show that I have it in its normal state now:

If anyone can help it would be appreciated because I need to lower LODs with distance for optimisation reasons. If any more info is required let me know. Thanks.

Check LODHandler.cs. It automatically changes the LOD of every generator in the scene each frame.

I'm not sure what exactly I should do with it...?

I finally tried having a Debug.Log in the SetLOD function to print the index it is about to set and it seems to run twice. One time it actually tries to set it to index 2 which I'm trying, then it does 0 again.

Which also explains something I noticed now, that for a VERY brief moment I see the planet being low resolution before going back to full when this runs. So I guess yes, something does set it to 0 although it may just me a mistake of mine.

By the way I should mention I am not using the SolarSystem scene, and the only reference to LODHandler appears to be in the Solar System scene. So I don't think it's changing stuff here as that scene isn't loaded.

I think I found it! I was stupid. Thanks for trying to help.

It was the PlanetTest script that was calling that other change back to 0 every time. I commented out the code and I switch between LODs with hotkeys just fine!
