      Fortnite style is cartoony but still using PBR computing shaders. Heres a example of what i'm talking about applied to realistic environment: - as you can see it's already realtime without need of compute lightmass.

        I tried using distance fields... didnt work very well for my geometry.. japanese style thin sheet walls... Besides i need max performance for VR so static lighting is best.

                            It was probably just changed from unpure to pure, why would you need the execution pin? You can always store values in variables if you don't want to recalculate a pure node.

                            I believe most of the issue IDs are internal in Epic's JIRA board, not all of them are exposed to the public website.

                              Just wondering...

                              stat UNIT ... now sometimes displays new info:

                              Draws ( not to be confused with the older "Draw", this actually tells you the current draw calls )


                              RHIT shows up in both Mobile and PIE debugging

                              But Mem, Draws, Prims only show up for Mobile (This is Mobile VR btw, Go specifically) but not always, and definitely not right away, it seems random. Is this intended or a bug? I feel All stats should show up regardless of platform.


                              But awesome to see!

                                Hey guys, just checked out the Vehicle Template on 4.21, movement is a bit jittery on the client.

                                When I opened my project and put vehicles in the map they went crazy and flew off, but I figure that'll be some settings or something that need changing, since the vehicle template looks pretty good replication wise.

                                Big fan of the new checkbox in physics replication too cool.

                                Edit: Can confirm after more in depth testing the fixes to the vehicles are excellent , a little jittery but no doubt that'll be to do with some fine tuning etc.

                                Thanks so much for this update guys, it's a masterpiece!
