New Renderer (OpenGL 3.3)

Thanks guys for the kind words! This really helps to stay motivated

The interiors look a little bit better (because of the improved lighting etc), but I have not yet processed any of the textures (I wrote some posts back what I do with them). Also, since there is no material system yet and I treat everything as metal, all the characters look like they are made of metal (which gave me quite a laugh in the beginning ;)). This is the reason why I didn’t show any pictures yet, it’s just not worth it at the moment.

I had to learn for another exam more than I thought (was for my minor in microelectronics) and after that I took a break. Freestalker has started to help me out with height maps, so I hope this will save me some time. I will get back working on this in the next week I guess. As always I have gotten some new ideas and perspective after taking a break, so I hope this will help me improving it further and find the last remaining bugs

Alright, I managed to fix lots of rendering issues and also completely changed the pipeline for upscaling the textures. Additionally I redid some of the height maps. You can see a video here: http://www.flnu.net/downloads/fl1410.mp4 I think it never did look that good before.
Btw. sorry for the stuttering. I was testing OBS studio with HEVC hardware encoding and there seem to be some issues, since I did not see them in the game.

Keep in mind that the textures are the unchanged vanilla ones.

Also Freestalker and I have been testing how to make new textures: http://www.flnu.net/downloads/flnewtex.png
But we are not finished, yet.

As always, feedback is welcome It helps me to judge whether I am doing the right things…

@eigos: They just lie in a folder and if the texture from a mat file is being loaded has a file with the same filename in it (e.g. “STADTL1_256.tga.dds” ) this one is loaded. Same applies to normal and ambient occlusion maps plus any future maps I might add (each have an own folder). I don’t know which material is being used, yet.

Actually I am quite surprised how well it looks now. Had some small ideas and the combination of them plus some rendering fixes really work well. E.g. I was not expecting how well it works here (apart from the rocks): http://www.flnu.net/downloads/fl1510.png

Today I finally was able to fix the fake lights in nebulas (fog did not work), so here is a video: http://www.flnu.net/downloads/fl1510neb.mp4

There is still some work left, but we are getting closer

Just boring stuff. Tested window management and OpenGL context creation with SDL2, but sadly the event processing breaks the controls. Plus it does not fix the wrong resolution in fullscreen mode (since FL manages the window, something seems to break there). Also I had to patch SDL2 to make it use an existing window with OpenGL.

I also did some further clean up and optimizations. On my NV 970m it is now nearly about 1,5 times faster as the original d3d8 renderer (with disabled shadows), but on my AMD RX480 the d3d8 renderer is faster. So either a driver problem or I am doing something wrong / something the driver does not like. Not much left I can do, though, since I have not that much control about how FL renders things. Sadly weapons fire also seems to impact FPS (on AMD). This is something I need to investigate further. I tested the newer OpenGL debug callback functionality, but neither on AMD nor on NV this helped.

Shadows also seem to impact the FPS a lot, but not when generating the maps, but when using them in the shaders. So I’ll have to investigate whether this is normal or not. Could be a fillrate problem, though. The scenes I am testing with have a lot of overdraw, since FL renders back to front and there a hundreds of objects. A z-prepass could help here.

I also have been working on getting the TB vectors generated like presented here: http://crytek.com/cryengine/presentations/triangle-mesh-tangent-space-calculation (there is existing c++ code but I need to adapt it to the UTF Editor code in c#).

As you can see, nothing of interest for the normal user (who doesn’t understand anything of the above anyway). I will post progress here when I have to show something new
