P3D V5 stopped working properly after ENVTEX, ENVSHADE, ENVDIR was installed

Hello

Sorry for not giving you a quicker answer, this is not the support part of the forum and topics here have a lower priority, that’s why I missed it. About the crashes, I’m sorry to say this is much probably not caused by one of our product, textures, when they are using the same format as the default ones cannot themselves create a crash to desktop in P3D. As for shaders, this is pretty much the same but they could indeed create visual issues. P3D v5 is still pretty recent and is not much stable yet and the crash issue probably comes from P3D itself, if the crashes appear only with Envtex enabled, it could only mean that for your specific configuration, some higher quality textures may create a crash, may be due to a vram issue or similar. Did you try to select the minimal texture resolution in Envdir then click install to sim again to see if you still had crashes? The Envtex entry in the scenery library is greyed-out because it is read by P3D as an addon package, and it is indeed supposed to be at the top of the list, this is only used by the aurora feature and it is at the top to prevent any 3rd party sceneries exclude bgl files to exclude the aurora effects. About your white screen issue, does this still happen with HDR disabled?
