Re: The wonders of technical art (Unreal Engine)
I would like to share something with you guys, that I discovered some time ago, but I didn't have nice use cases to show it off. Now in the ray marcher, it saves me a lot of time, and simplifies and shortens the hlsl code that I actually need to write. Hopefully it will be useful for someone else too. It is about adding… -
Re: The wonders of technical art (Unreal Engine)
More fun. Here is a ray marched menger sponge: I used the classic approach where the menger sponge code lives in a custom ush file included into common dot ush for ease of use in the custom node. Then its ray marched in the custom node, and normals are calculated using 3 extra samples in the end, after the marching loop… -
Re: The wonders of technical art (Unreal Engine)
It is specific to unreal engine's material functions and how it generates the hlsl code, if you use UE4's global shader it works fine. From what I remember it just copies the code into the material expression and based on the error message I am guessing that when it translates the expression it cant compile function… -
Re: The wonders of technical art (Unreal Engine)
Wearing a cube on my "head" if I want to see the effect is also ridiculous. :D :D Is there any way to fix this? For recap, if I use a post process utilizing distance to nearest surface function in code, it only works if I have a mesh using the same function as a node, on screen. Otherwise I get black image. Like it doesn't… -
Re: The wonders of technical art (Unreal Engine)
Any input from anyone regarding usage of render target buffers, except that I can make the whole thing half res relative to the actual resolution? For things like the dfao from the last page, thats cool but for the pure ray marched ones, it would be just like as if you would use 50% screen percentage. So I don't see much… -
Re: The wonders of technical art (Unreal Engine)
I noticed some changes in how custom ush files works in the current versions of Unreal. Earlier it used to be like if you use an external ush file so you don't embed your code into an existing one, the engine won't recompile the shaders when you open the editor. But what happens now, is that it will recompile upon opening… -
Re: The wonders of technical art (Unreal Engine)
Got the whole scene to reflect and to be reflected. So far I'm getting really good performance, and I'm curios to see how much worse it gets once I start adding much more complexity. Currently I'm having nearly 500 fps on a 2080ti on 1080p resolution, when the scene fills the whole screen. Next time I'll add reflections on… -
Re: The wonders of technical art (Unreal Engine)
There shouldnt be any downsides. Another approach you can take that is to basically inject hlsl code into the MaterialTemplate. It is described here http://blog.kiteand lightning.la/ue4-hlsl-shader-development-guide-notes-tips/. You have two material functions one to define your structs and one to use them. The upside is… -
Re: The wonders of technical art (Unreal Engine)
@Mant1k0re - A public version is planned, but I don't know yet when it will come. It will be similar to CryEngine's master material. I still have to fix and add a lot of features. It should be completely universal. Anyways, here is an update of the Model Viewer. New features: Rendering mode: - Albedo channel can be… -
Re: The wonders of technical art (Unreal Engine)
Holy hell, this one sucked (for several stupid reasons), but I think I have it working. Let me see if I can summarize: First things first, in a BP, you'll need to kick out some basic "camera" data. Again, this doesn't have to be an actual camera, it could be a helper widget, or mesh position, or whatever. but you'll want…
