impressive how quickly you made a video for the new update. Loved the old one because it explained all the complexity and didn't need this one because it was so straightforward (which says a lot about bevy)

Thank you for the tutorial, it really helped me to get started with my project!

thank you so much for updating this!

This is awesome, thank you for explaining the new material system so clearly. I would love it if you did a video on the new UI system as well!

Many thanks for this!

As seen by views and upvotes, all of your videos are highly underrated. Thank you so much for all those tutorials! ❤

real nice derives

Thank you a lot❤

Thanks for making this - really helpful! Maybe you could go a bit slower since it's hard to read and digest the code before it moves on to the next part Cheers : )

The engine is progressing so fast that it might soon rival unreal and unity.

It's a great overview, but IMO for a new viewer as me having that much references to the old video is hard to follow, and at the same time I'm not super motivated watching the old one to understand as it's fully outdated :) Nice work tho keep it up

Thank you so much, this is exactly what I needed to get up and running! Can I ask a really stupid question, what font are you using? the bold const `HEIGHT` and `RESOLUTION` look really nice for some reason :P

Do you happen to know much about the camera system as it currently stands? I saw a "DepthCalculation" field on the struct, and didn't know if that could be used for "depth of field" effects. That's certainly something I hope they get in there with the "post" stuff they're gonna be working on (if it's not already part of renderer - haven't tried the depth calculation yet) I was reading article on Unreal, and it's basically just splitting into 3 layers, blurring front and back layers, then blending them all together. That one effect can really change a game imo. Make it much more realistic. they have kinda a "high end" and "low end" modes (cinematic and game) in Unreal. Not a bad idea to have 2 options here even for real-time (support all cards with improved experience if newer card exists in system) That brings up a whole other topic - Feature Detection - but maybe all that stuff just handled under the hood, and not by app dev. I guess it's mostly wgpu based feature detection really, so framework could just shift rendering algorithm incrementally based on hardware 'capacity' available.

I played around a little with materials and shaders too and ask myself, is using prepare and extract necessary, or why can't you just set eg the color property of CoolMaterial directly?

I love that it is now this easy to create custom materials but i did some testing and found that MaterialMesh2dBundles performs much worse compared to SpriteBundles. 1024 SpriteBundles on the screen: 111fps 1024 MaterialMesh2dBundles (quads): 86fps I am yet to put a finger on what exactly causes such a dramatic performance loss but it is definitely not the shaders or uniform updates because even a shader that simply outputs a color and has no uniforms performs the same. So far I found 1 way to customize a shader with 0 performance loss (performance gain actually, 116fps!). You need to copy Bevy's Sprite implementation and modify it directly but that's a lot of code that needs to be comprehended. My guesses why MaterialMesh2dBundles perform so much worse than SpriteBundles are: * Sprites use hard coded quads instead of mesh resources (most likely) * Sprites have less vertex attributes

I think currently storage buffers are left out? You need to go over all the dirty works to use storage buffers

You introduce yourself with Howdy, are you an aggie by chance?

I feel like video could have been a bit more applicable to a broader audience if more time was spent on discussing some of the basic ideas and principles. For example, (1) what is a shader/shader program/material and when would I use them, (2) what is wgpu, and (3) how can I apply this knowledge to, for example, an existing scene built from GLTF assets in Bevy?

imo it is still complicated and intertwined😢
