viewer.rs has a different render result with render.rs

[oUp2Uo]

Thanks for the great work, it is very useful to view the compressed npz model.

Today, occasionally, I found viewer.rs has a different render result with render.rs for a same model on the same camera position. And this is the first position.

viewer.rs

render.rs

Not all position different, just 1st in this image sequence(~60). I have tried to change the rendering order of test and train, and this time the 1st in train got error. It seems that render.rs's result is not correct at the first position.

Do you have any idea about this? Thank you.
