I've been making great progress on my #Unrealengine tool for helping you find optimisation opportunities and potential bugs in your #UE5 levels It's pretty much there, few more bits to go. I started writing up the documentation and need to do a bunch of testing to make sure everything... works as intended! There are currently 91 searches you can run: - 46 optimisation searches across 11 actor types - 45 bug searches across 10 actor types People seem most interested in lighting optimisation, so here are a couple of examples of the light optimisation searches you can run: 🔸Lights with no max draw distance set 🔸Lights with Cast Shadow enabled/disabled 🔸Lights with specific mobility modes 🔸Lights with edited lighting channels Let me know what you would most want to be able to search for! #gamedevshow more

Do you have the option if a collision is complex or simple? That's one of the biggest performance killers in a game.

James Rowbotham1 year ago

I have collision in general, but yeah using complex or simple would be good. I think I’ll need to find a way to read the project configs as collision can be set ‘project default’, which makes things a bit more complex to work out what’s what. I’ll definitely look into this though

This is the biggest productivity cheat code right now. Kiss reading documents goodbye. You can get an instant summary of any document with this tool.

Thanks Jack, hopefully it’s going to save people a bunch of pain!

Where do I buy this? 😁

James Rowbotham1 year ago

Ha it’s not out yet, I’m working on the last bits and testing it all works doing documentation and videos. If you give me a follow I’ll post when I launch it!

I’ve released 2 tools now to help OPTIMISE your #UnrealEngine projects. The same ones I use in my own dev workflow 🔍PROJECT OPTIMISE: Gives a holistic view of your entire project's content to find potential bugs and performance issues 🧠LEVEL OPTIMISE: Focuses in on individual levels to help catch actor-specific problems I usually run PROJECT OPTIMISE first, then dig deeper into specific level actor issues with LEVEL OPTIMISE, helping me to find bugs and optimisation issues across my project fast! In the video below, I’m using LEVEL OPTIMISE to: 🔸 Run a 'Lights' health check on my level to reveal lighting issues 🔸 Quickly dig down to find any lights that have a no max draw distance set 🔸 Run a 'Static Mesh' health check on my level to reveal static mesh issues 🔸 Look through a list of actors which do not have nanite enabled Check out the tools here 👉 #GameDev | #indieDev | #UE5 | #GameDevelopment

5001 lights in WebGPU (Shade). 1 directional shadowed light with CSM + 5000 sphere lights. Using clustered lighting, similar to Unreal, the screen is split into tiles of 32x32 pixels and then further split along the Z axis. Lights are culled and binned. Most of the time engines implement clustered lighting with a fixed number of partitions in XY, something like 40x20, let's say, this is generally fine, but it doesn't adapt to different aspect ratios and tends not to scale as well into higher screen resolutions. Finally, by splitting the XY in 32 pixel increments (or anything that's 2^N really) - you get better wave coherence, that is - pixel shader runs more efficiently. The engine supports up to 10,000 so-called "local lights" in the frame, which can be either be sphere lights (point lights with volume) or spot lights. When I say "in the frame" - I mean on-screen at the same time. There can be a million lights in the scene for example, but only 10,000 can be visible at a time. Can increase the limit, but I reckon 10,000 is already a pretty (un)reasonable limit.

she's right, this method to find app ideas is insane. i've been sharing my app ideas for months now and i've found most of them on creator search insights. what you should look for: > 100k+ weekly searches > you scroll and see videos about it you can be the 1st in your niche.

This is, by far, one of the best uses of modern AI. If you don't use embeddings when querying your database, you are definitely leaving a lot on the table. In this video, I'll show you how to run semantic searches using OpenAI and PostgreSQL. It's all thanks to Pgai, an open-source PostgreSQL extension: Here's what will happen: 1. We'll create a simple table with news articles 2. We'll generate embeddings for those articles 3. We'll run queries on top of those embeddings For this video, I generated the embeddings using a simple query, but pgai Vectorizer would do the same automatically as new information makes it into the database. This is awesome! If you have a PostgreSQL database with data you are searching over, you should start experimenting with semantic searches immediately. For most use cases, a combination of full-text search + semantic search is the best approach. If you don't have a PostgreSQL database around, you can try free for 30 days using Timescale: Thanks to the Timescale (now TigerData) team for partnering with me on this post!

Here is an open-source tool to generate a complete dataset. 1. Describe the data you want 2. An orchestrator agent searches the web 3. Sub-agents run in parallel to fetch the data 4. You get a structured dataset you can download For example, you can run Bigset with the query "all leica lenses being sold on amazon", or "leica stores in kyoto with their opening hours and ratings". Bigset uses TinyFish's free Search and Fetch APIs in the background. You can configure it to refresh the data on a schedule. You can self-host it with your own keys. Here is the GitHub repository: You can get free TinyFish API keys here: Thanks to the TinyFish team for partnering with me on this post.
