Hello! I’m trying to create an effect with over 10,000 cards that update their position every frame. My naive implementation used Paper 2D Sprites, and it was breathtakingly slow. No surprise there. I switched to building something off of this example procedural mesh component (which is derived from CustomMeshComponent), which works better, but still is much slower than I would hope.
In digging through the code, instead of updating the vertex buffer, it recreates the vertex buffer every time you update it. Since I have a fixed number of cards, it seems like I should create the vertex buffer once with BUF_Dynamic (or BUF_Volatile?) and then lock it every frame to update the coordinates. In looking over the code, I’m not really clear how to do that since it seems like I can only modify it in the render thread and there are quite a few support objects
Does anyone have any sample code that does this or something similar? Is there an easier way (something like glDrawArrays)?
Thank you so much for your help!
