Refresh: doing it only once as with thin instances

[Dr.Hell]

Thin istances are very powerful. Using them I increased the speed of maybe a factor 20-30x.
But even more interesting was that using correctly the refresh flag in thinInstanceAdd, setting it always to false, and to true only for the last one instance, there was another full order of magnitude improvement. Which moved a situation from a jerky experience to a smooth one.

Now, I wonder: if I have a great number of different meshes that are not exactly the same (so thinInstance can’t be used), does it make sense to worry about avoiding the refresh of the gpu buffer while adding the single meshes to the scene?
Is it even possible?
If possible, would it have a significant impact on performances, like with thin Instances, or in this case the impact will be negligible?

Hi! I was playing with similar stuff a few months ago. You could find something useful:

Thinnizator - automatic thin instances

Hi guys! EDIT: PG link updated: https://playground.babylonjs.com/#QZA92W#151 Entreé This small script automatically creates thin instances of meshes located under a given node. It doesn’t care about the naming and tries to automatically find all “equal” meshes on the scene, creates a prefab mesh for the equal meshes, disposes the original meshes and creates the required amount of thin instances from the prefab mesh. The thin instances are positioned/rotated/scaled as the original meshes. The…

And there is a tool also which gives you a guick overview of thinnizable meshes (if ur gonna give it a try, use drag’n’drop, I broke the load button with the last build):

Thinnizator Playground

Hi guys! I’ve created a playground for the Thinnizator using Quasar and Vue. If you don’t know what the Thinnizator is, the original post can be found here Thinnizator - automatic thin instances You can load your model into the scene, hit the Check Scene button and you will get a list of meshes which can be thinnized. The first columns displays the prefabs and how many instances can be created from that prefab. The scond column are the instance positions. The locations of prefabs and instanc…

That sounds very useful for some prebuilt scene. Great stuff.
