https://github.com/rbray89/EnvironmentalVisualEnhancements/commits/Overhaul/x86-Release.zip I'm excited that rbray is coding again, and that you are already making some awesome effects with the new stuff! Anecdotal but maybe it will help isolate: I'm using SVE 0.3.0 with EVE-WIP from Oct 29th drop (the beta prep one) without issues (my gut says the cloud separation that rbray started 2 days ago might be a source of pink effects).

I did an analysis on several space plane designs and some of my own. There are some ratios i've calculated out that i use as a rule of thumb. total_mass * 35-60% = total_fuel_mass >> Does not including dry mass of fuel tanks - keep ratio of LH to O2 at about 2:1 or 3:1 total_mass * 10-25% = combined_engine_mass >> You need about 1 rapier per 16-20 tons of total mass - 20 tons per rapier makes for very shallow ascent profiles, 18 is a good spot, 16 tons per rapier usually means you can practically just aim at 20 degrees the whole way and you'll get to orbit total_mass * 6% = fuel_tank_dry_mass >> fuel_mass / 8 = fuel_tank_dry_mass (about the average weight of dry tanks) total_mass * 4% = lift_body_mass >> total_mass * 40% = lift_body_needed (I aim for about 40-45% lift units, if you have lots of TWR you can probably get away with less - e.g. 20t craft should have about 10 lift units total) >> lift_body_needed / 10 = lift_body_mass (average weight of most lift bodies is 1/10 the lift) total_mass * 10-45% = other_parts_mass >> "other" variable fixed part mass costs like: >> cockpit, landing gear, airbrakes, tail fins, air intakes, batteries, solar panels, science equipment, radiators, filled ore tanks, etc. How I apply it: I always start with 50% fuel ratio, 20% for engines, 10% dry tanks/wings, and other stuff to 20%. That's what I expect for a reasonable flight profile (climb at about 20, level off at 10k, gain alt slowly, activate o2 around 25k, aim for AP of 75k'ish, circularize). Step 1) I usually start with the number and types of engines first (say 2 rapier and a nuke - 7t of engines) Step 2) With a 20% engine ratio, this means my total mass should be around 7t engine / 20% = 35t Step 3) From there I figure about 50% fuel as a baseline expectation (17t fuel -- 3:1 ratio so that's about 12.75t lh and 4.25t o2) Step 4) I presume 10% of total mass goes toward wings/dry tanks Step 5) remainder goes toward other stuff, but i try and restrict this to 20% if at all possible (so 7t limit of cockpit and other stuff). I'll start building with these goals in mind, putting together fuel tanks, then engines, then wings (balancing CoL), then put on other accessories. As I build it, and it comes in UNDER 35t total, I know I can expect the flight profile to be more relaxed. If it comes in OVER 35t then i can expect the flight profile to be more finesse and shallow ascent. These rules work even for big birds - e.g. a 180t bird i'm working on now. If you want to have an even more lazy flight profile - go for more engines and more fuel and reduce your 'other' mass: 55% fuel, 25% engines, 10% dry tanks/wings, 10% other - That will very likely do a 30 degree fire-and-forget style ascent profile.
