Tried hooking up Niagara data interfaces to #ImGui texture visualizer. Too much work to cleanup + properly support ^^' #UE5

Trying the FAB thing! fab.com/listings/0266b… Cleaned up and added some optimizations to my #Niagara Procedural Mesh plugin :) #UE5

🥳🎥 New YouTube video just dropped! A quick 20-min dive into the basics of Niagara’s Dynamic Mesh interface + a breakdown of a more advanced (but flawed/experimental) use case. Link ⬇️ #UnrealEngine #Niagara #VFX

Added a cute little texture inspector :) I think it pretty much has all the features I use with Renderdoc texture viewer now. #ImGui #UE5

Added support for more texture formats + UI improvements. #UE5 #ImGui

Reason why I have stopped releasing stuff recently. Working with launcher engine + handling these kind of issues is a pain >_< One line fix when compiling from source... :(

Simple #ImGui tool for debugging render targets :) Not sure how practical it is, just wanted something to test the imgui callback setup :p #UE5

Tried a simple #ImGui tool for reviewing/previewing shelved asset changes. Requires a strictly read only workflow to not mess up the local workspace :p #UE5

Improved ImGui widget integration, looks like a native tool now :) Also added filtering and improvements to ImGui asset picker. #UE5 #ImGui

Tried modifying my #Niagara outline setup for blending meshes, benefits from the same kind of optimization... Based on the mesh blending technique shared by @toreler #UE5

Added some optimizations for updating connectivity info. Still using shapematching + connectivity info to group pieces at runtime. Also tried a basic constraint based setup but performance was quite bad (graph coloring kind of explodes for these type of setups) #Niagara #UE5

Spent some time optimizing the Nanite pass for portals. Forcing HW raster mode to speed up stencil tests + SW path no longer has to deal with portals so removes some overhead from there. #UE5

Now that InstancedStaticMesh supports GPU culling and LODs, are there any advantages to using HISMC :? Mostly for things like foliage (instances are not updated at runtime) #UE5

Fixed Lumen visualization mode, seems like it doesn't account for global clip planes :p Doesn't seem to cause any major visual difference :? #UE5

Tried a single pass #Lumen setup for #Portal Unfortunately some steps do require per camera setup so not as fast as I had hoped and adds a lot of complications :p Seems to scale well with portal size on the screen. Hopefully scales well with portal count too... #UE5

Has anyone looked into what's the best way to compare #Nanite vs NonNanite rendering performance (mostly looking at base pass)? I tried `r.Nanite 0/1` but the nanite fallback mesh can often be quite low res compared to original mesh so not a very accurate comparison :? #UE5

#Portal with custom shape :? Tried recreating Dr. Strange's portal effect. Handling particle collision seems tricky, can't use DF as portal blocks it and depth buffer is kind of messed up :p #UE5
