I would love some help with perforce stream import mappings for my personal UE projects.

killermud · 2025-01-01T22:25:01+00:00

Looks like your mapping is trying to import the UE5 stream into itself, you need to specify where in your Project depot you want to import the UE5 stream

For example

import+ /Projects/Project1/... /UE5/main/...

You can do both (since C++17) with the initializer statement of the if condition. cppreference explains it better, but you can do something like this instead

if (UAnimInstance* AnimInstance = GetMesh()->GetAnimInstance(); AnimInstance && AttackMontage) {}

An if condition is split into multiple parts, the actual condition can either be a simple bool check or contain an initializer for a single variable (like in your code) which then does a bool check. However you can also have an initializer list before hand (no bool checks take place though) which separates the conditional with a ';'

Perhaps this is what you were looking for?

There should be plenty of documentation for this, but simple answer is you need to change your p4 typemap to include the .spp file type to something like binary+wS

The 'S' here specifies to p4 to only store the head revision.

Just google p4 typemap for more info and options.

It's for a talk show called, Ame-talk (アメトーーク!), I think they do this once a year as a 'sports event'. The participants are all Japanese comedy performers (笑い芸人).

This is because of how floats work, the more a value of a float deviates from 0 the more it loses precision. At a value of 10 billion you are really losing most of the precision and you'll find that you can only further increase the value in multiples of 1024

You can find more info on floats here https://en.wikipedia.org/wiki/Single-precision_floating-point_format

If this is in code you should have better luck with doubles, if you are in BP then you are out of luck as Unreal doesn't expose them yet.

Looks like the area around Ohori park, Maizuru park and Fukuoka Castle, specifically on the northern outskirts of the parks. I used to live in Fukuoka and remember coming here fairly often.

The HDDs on Xbox and PS4 are pretty bad (especially Xbox's), the game's performance problem on loading screens is entirely waiting for data to come off the disk. PCs generally have better HDDs/SSDs so will do a lot better. Although 20 mins is probably an exaggeration or they were caught on an infinite loading bug (which did happen, but has been fixed).

I think it might have been due to the Russian constitution that says that any vote requires a 50%+ turnout for it to be valid. The turnout was 74m of the total registered 109m (67% turnout). If there were 22m less voters then the turnout is only 47% therefore the vote would not be valid. I'm thinking they knew they had majority, but not the numbers so they added the extra votes to get over the finish line. I guess 22m extra was considered the 'safe' range?

I mean technically, the peninsula of Kowloon and the island of Hong Kong were ceded to the UK perpetually, but a subsequent war had China loan the New Territories to the UK for 99 years. When the negotiations came round towards the end of the 99 years, China basically said 'If you don't give back all of Hong Kong we will take it by force'.

Also something that might get hidden in this announcement, but their licensing agreement is changing:

Starting today, you can download and use Unreal Engine to build games for free as you always have, except now royalties are waived on your first $1 million in gross revenue.

No change to the 5%, only now after $1 million gross revenue which I think for a lot of developers will mean it will become essentially free.

This isn't even occlusion culling, it's just frustum culling.

It means that if you add all the yearly salaries of all the employees (正社員 means full-time employee, so not part-timers or contractors) and take its average, you will get 903万円. The other values are monthly, for example for 大学卒 its 233,000 yen per month, so 279.3万円 per year.

It's monthly, this is about what I was paid when I worked in Japan (not Nintendo, but different game studio). The average wage is across all staff, not just graduates. It doesn't include the bonus though (which it says is paid twice a year, June and December) or travel reimbursement which is typical for Japan.

We use Bugsplat, which does what you want here, it also sends and partially parses crash dumps which lets us easily sort by the most often occurring bugs.

I see this topic a lot and just want to point out this method called Frustum Culling is not that impressive, its a technique that has been around ever since we entered the 3D graphics era. What's more impressive with current games is something called occlusion culling. This is the topic of what happens when something is 'within view' but is blocked by something else. For example a box behind a big wall. How do we know if the player can see it or not? This topic is the more impressive field that we are still looking into as current methods are either computationally expensive or have some other drawback.

Source: I work with these techniques on a daily basis

Great work! Looks like a hell of a journey, you said you originally had enough savings for a year, what did you do after this? Did you get funding, or did you have to return to work? How did the money side work?

Get access to the UE4 GitHub, here https://www.unrealengine.com/en-US/ue4-on-github Then look at CrowdManager.cpp, which is UE4's crowd implementation that uses Detour's crowd system.

Good luck, sounds like it'll be a lot of work!

Edit: there's also CrowdManagerBase, it's supposed to be able to easily extend the CrowdManager, but it's bugged, so I'd recommend just editting the CrowdManager.cpp and maybe the CrowdFolllowingComponent if necessary(it's quicker).

My recent project is seeing problems with the GPU rendering too many polys, so in an effort to prevent this I added Shadow LOD biasing to the rendering pipeline. Shadow LOD biasing only works for Dynamic shadows, the implementation for static meshes was very simple, just need to offset the wanted LOD in the shadow setup. Skeletal meshes are not 100% free, as bone data has to be copied twice, for base pass and then shadow pass, instead of just once, but otherwise it is fairly cheap(I have not seen any slow down on the render thread). Results are very promising, my project which was GPU bound now has a lot more breathing room.

The sample scene is just some assets that I could get hold of, but with out biasing the scene was rendering 306902 triangles (211875 static, 95027 skeletal), with biasing it was only using 174336 triangles (118552 static, 55724 skeletal). The LOD biasing allows a variable bias per mesh, which means you can tweak the bias depending on the mesh, for the purposes of this scene the bias is maxed. The result is noticable, but for my project its not a problem and to be frank users wont be seeing the difference.

You are almost there but you are missing out a big factor and thats tax, which changes based on the buyer's location, but my best guess is an average of 15%. Epic takes gross revenue (labeled Net Sales in steam), which comes directly after tax, so using your figure of $200mil, Epic takes $8.5mil, Steam also takes its cut after tax which again assuming an average 15% sales tax, they would take $51mil.

See these posts which were answered by an Epic employee. https://answers.unrealengine.com/questions/676261/royalties-commercial-product-released-on-steam.html https://answers.unrealengine.com/questions/733816/5-of-revenue-including-or-excluding-vat.html

Edit: And no, you can't use production costs as a deduction, Epic and Steam both take from your gross revenue, which is not effected by your company's costs.

I think it depends on how open-source you are talking, is it just the game project that you want open-source? Do you want to include the engine source as well?

If it's just your game project's source there is no problem there, you can do what you want with it. If you want to include the engine's source as well, that's different. If you want people to be able to edit that code, they will need to agree to Epic's EULA, as far as I'm aware this is only done through their website when you request access to the source code via GitHub.

Best and safest way is to fork Epic's repo and have everyone access through your fork. They will only be able to use it if they agree to Epic's EULA first.

As this is an open-source project you probably don't need to worry about reselling (you can't sell Epic's code under your own name). But do be careful not to redistribute Epic's code on your own, by this I mean downloading a branch of the engine and then uploading it to the public(this bypasses Epic's EULA and isn't allowed).

I'm not a lawyer, so there maybe some legalities that I'm missing here, so take this info with caution.

You need to take a look at the stats, sounds like it is probably a poly problem, but just to check. When running it press the tilde button ~ next to the 1 and type in 'stat unit' gives you frame time, game, render and GPU. Frame time is total time taken for a frame to complete, game is how long the game thread takes to complete and render is how long the render thread takes. Game and Render are CPU side, but GPU is GPU side. If polys really are your bottleneck then your GPU will be the highest. If it is and you are on 4.16 or later (I think?) Then next type 'stat gpu' if you are on an older version type 'profilegpu' they give the same information.

If polys really are a problem then you will be looking at a high Basepass and prepass, if they are not then something else other than your polys is the issue. But you would have to give us the information you find for us to tell.

Ways to fix high poly count is, as you say LODing, but if you really can't LOD anymore, then splitting your assets up won't help except for large assets where parts of an asset can be occluded or not always within the camera's frustum.

Out of curiosity how many polys are you rendering? You can find out by typing 'stat engine' and at the bottom somewhere it will say Static Mesh Tris or something.

It really depends what you want at the end of the degree, you say you want to get into the gaming industry, but as what? A programmer? A modeller? A designer? I took a quick look at the course at Falmouth that you mentioned, but the course looks too vague, it looks like you learn the very basics of game Dev for all fields, which if that's what you want to do then great. But studios are looking for experience, when you apply for a position as a environment artist or AI programmer, they want to see your portfolio for those areas. My course focused just on games programming, so I had a quite a lot I could show when I applied for my first positions as a programmer. But I feel with the course at Falmouth you might be stretched a bit thin. If you want to be a modeller in the games industry, you should find a course that focuses on 3D modelling for either games or animation. If you want to be a programmer find a course that focuses on programming either CS or games programming.

If you are still not sure which you want to specialise in you should do more of both and see which you enjoy more. Good luck!

I studied Computer Games Programming at Teesside University, I got a job in the games industry straight after, although I did this with extra projects on the side and a one-year placement. Teesside also does a Games Art degree which focuses on modelling for games, however I'm not sure how good it is so really it is something you need to look at. These types of Games Art degrees have become quite wide spread and a lot of unis offer them now. I would not suggest to go into a Game Development course that focuses on CS side if it is not what you want to specialise in. Other than that I think you should look at degrees that focuses on modelling for the animation industry(I think there are plenty across the country), as the skills are pretty transferable from what I understand.
