Hello, X-Plane 11 11.51r1, using SMPv5 5.0.6 and FSGRW and RWC. When i have changed the cloud textures a few times then XP crashes, and log says due to plugin SkyMaxx Pro... It is not a problem of RAM space! I have 32 GB is a lot of free space when this happens! (I specify that I do not use volumetric clouds pad). Second problem: clouds with black textures are sometimes visible with Cumulus Swept. I am on the verge of roll back to v4 .....! Help!
