![]() X-Plane 12 has a lot more stages and processing in its pipeline than X-Plane 11, and that was consuming VRAM. The render graph allows us to double-book VRAM used to render the main frame. Rendering graphs are all the rage today if you’re curious about this you can look at something like AMD’s Render Pipeline Shaders. ![]() The biggest change to X-Plane 12.06 is not one you can see: we’ve converted the main rendering pipeline from 12.0 (which was hand coded) into a rendering node graph. I’ll try to provide clear guidance and early builds when we get to this point, but lighting is still “in development”. My expectation is that when we recalibrate cockpit lighting, minor aircraft updates will be needed, but third parties who have chosen to “fix” cockpit brightness themselves (by adding extra light or hacking materials) may have to undo their hacks. Improving dark cockpits is high on our todo list, but we also don’t want to tweak the light levels in the cockpit over and over and over, thrashing third party developers each time we do it. make one patch to update lighting once we have all of the changes. We have a bunch of lighting fixes internally, but the plan is to measure twice and cut once, e.g. X-Plane 12.06 fixes some constants for sky colors but is not a lighting update. The future: we are looking at putting a 2-d “cloud shell” behind the 3-d clouds to handle orbital view and make the planet look less silly, and we’ll be going over real weather with a fine tooth comb. Thick prism-shaped cirrus clouds should also be fixed, and we’ll be tuning up the presets and METAR parsing. square cubic clouds, especially with real weather) should be fixed in beta 2, so enjoy them while they last. While there are a few real weather fixes included, we have not tried to comprehensively update real weather my thinking was that without proper rendering, it would be impossible to tell if real weather was actually getting better.Ĭoming soon: “Minecraft clouds” (e.g. Alex and I rebuilt the noise functions that build each weather type to get better looking clouds of all types.The cloud shaders also contain a dedicated path for cirrus clouds that should look better than what we had in 12.0 (“really thin stratus clouds up high”).Daniel rewrote the way clouds are marched, fixing zebra stripes and generally making things less pixelated and ugly. The cloud shaders are now faster and have fewer artifacts.12.06 ships the first two steps in this multi-step process: Since X-Plane 12.0 shipped, we’ve been working on the clouds and the weather system to improve performance, accuracy and quality. Here’s a few of the bigger things we changed, and a few notes about the beta process. X-Plane 12.06 beta 1 is here! And it contains a lot of changes.
