So now I've solved the thrust vectoring issues, it is time to focus on an ascent program, and implement some details like separation motors for Stage 1/2, and implement the RCS system for Stage 2.
I made a test on manual control with a 5-tons Carina as a payload, getting to LEO was a walk in the park. I have like 95% of the second stage remaining. Tianwen-1 is 5 tons too, so all that fuel should allow a Trans-Mars Injection.
The separation sequence with the second stage separation motors firing. I wrote a nasty script that brings me halfway to LEO. The rockets tends to kick around like a young mustang but it gets the job done, and can be refined with a pseudo-PID. Now all I have to do is to write an "altitude holding and orbit circularization" thingy.
Jarmonik's new shader looks real great, just "more real". Which is the whole point of PBR
Long March 5 on the right track, using the real launch azimuth value. I'm still into the first stage ascent program (more an ascent script, really) but most of the hard work is done, now I only have to make things a bit smoother. Also working on a 7-seconds ignition sequence that matches what I've seen on Youtube (you have spark igniters, the LOX/LH2 core ignites and reaches full thrust, then the Kero/LOX boosters ignite and reach full thrust, then the boosters clamps are released. Once tower clear the roll script kicks in, followed by pitch and yaw.

@jarmonik : using the new shader, I get a yellow-ish second stage (it should be white). Thing is that the lower part of that stage and the interior material of the interstage are actually yellow-ish, so maybe it is yellow-illuminated by them ? How could I fix that ? I know it is WIP, so let's see how it works with next release.
Those handrails gave me a "good time" Also I modified the shape of the building 2 or 3 times, as I understood better how it was built. I'd say we're pretty close from the real thing now. Now I used pictures from both Wenchang launchpads for modeling, at first I wasn't even aware there was a second pad. They are similar in dimension, but the second pad is built for lighter rockets. So you might notice some inconsistencies with the "heavy" launchpad ; I'd say that's an acceptable tradeoff : you'll be able to use both launchpads if you want to.
The elevator shaft in the middle is painted with a nice tropical blue, saw that on pictures. Some pictures were probably taken right after the construction and the concrete looks raw, but on others they obviously added a nice layer of paint.
The Launch complex structures are almost looking good so far... I am expecting the intended payloads for the Long March 5 to be developed for the addon as soon as the LM5's future payloads are launched.
