I helped with the two Louis Vuitton projects on there, both were done in Unreal as well. As you can see from the other projects, real-time graphics can be used for a lot of things!

I'm not that deep into it myself, but I can use it if I need to. Once I'm done with slowly working through the Book of Shaders I should take another look. Curious to see what you're making in it Liv!

And while not technically an engine, Houdini is some real powerful software as well for procedural design and creating a quick pipeline that works with Unreal and Unity.

The way I see it is the push Epic have done with Unreal and Twinmotion has shaken up the industry, it's just a slow shake.

I'm seeing people showcase gorgeous interior renders on LinkedIn, everyday. They are obviously strong, and sell the space in a static image. But a static image is trumped by a walkthrough movie and a movie is trumped by realtime interaction and that is improved with VR.


Unreal 4 isnt easy to learn but it is easy to grab hold of.
Twinmotion is a piece of piss but limited.

Hi Roujin, I can make your sketchup, Revit, Archicad sexy it is super difficult, you wont understand DM for day rate.

Very much so.
When I was at the Unreal Acedemy I attended a lecture on lighting types and their application. I was in awe of it all but the more versed people attending where there for that specific stuff.
I will try to link tomorrow, alot of the lectures are online.

Ray tracing is a part of, a major part of what I have worked with for years. I have nearly always worked in what is referred to as PBR (physical based rendering), we take a light source, shoot light rays out of it, when that ray hits a surface it calculates the colour, reflection, roughness, texture etc, then leaves with that data until it hits the next surface until that calculation starts again.

That is crazy heavy on computation power. What Unreal and similar have done is to minimize those aspects normally at a loss to detail but in a way where the designer can dictate those losses.

That is about as simple as I can get but anyone who is interested and has even a halfway ok PC or laptop just download Unreal and have some fun. You can literally be in a fps within a few clicks.

Yeah the traditional renderers were/are ray traced.
Ray tracing really is the default because it is based around physics of sun light. PBR (physical based rendering) is the default, the starting point. From there it is always an attempt to cut corners and trick the viewer. Which is fine, all balance.

Twinmotion is indeed the shit.

Does unreal have Ray tracing? I was looking at the digital foundry Minecraft video and thinking how amazing the tech would be when applied to an architectural design program in VR.

UE and Frostbite have very much lead the way for real-time ray-tracing. One of the first big demos was running in UE:



Of course, at the time it was running on a DGX-1, which cost $70,000 and had 4 Tesla V100 (top end NVIDIA quadro) GPUs.
UE, the DXR team and NVIDIA Turing cards (with the RT cores) later optimised things so it would eventually run on a single RTX 2080 TI, which is still a beast of a card but shows you how quickly tech is moving in the sector.
The next year they also got this demo running real-time on an RTX 2080t Ti:



RT is now fully officially supported in UE since 4.24, while Unity are still lagging behind a little as they've got lots of engine changes in flight for the new render pipelines so haven't gone at it full bore:  https://docs.unrealengine.com/en-US/Engine/Rendering/RayTracing/index.html

PS, if you want to mess about with UE ray-tracing you don't need an RTX card - it works okay if you have a decent GPU, just obviously not as fast as RTX, so the viewport is laggier and the image takes a little while to refine the noise away. Just about tolerable to have a look at the demo scene on my GTX 1070, but you wouldn't want to work with it all day.

My people work with Unreal almost exclusively and have a sort of partnership with Unreal and therefore have access to GPUs like those listed, doing virtual production stuff, all realtime. Unreal is moving ahead pretty quickly. I was using it with Hololens to do some vis of Solidworks models, passthrough stuff using real-time ray tracing, s'good.

Almost at a point where I am happy to call it done - some texturing and one or two more assets to do - some weird effects when i stand in certain places that I will have to troubleshoot too.

That looks really good, Temps.

I'm going to start learning Unity and get back into some basic game development jazz. Thought you would all want to know.

I wish all this shit had been around when I was learning to make Dink Smallwood modules in the early 2000's! Man.

I downloaded Unity and GameMaker recently. Really wanna make something.

Oooh, nice. I have been tinkering with the same combo. You mainly looking at visual coding? Or actual nuts and bolts codey-code?

I never gave it much time, but Project Spark was a fucking brilliant little thing.

What sort of game would you want to make, Elf?

I did look, to be fair...
