New Renderer (OpenGL 3.3)

@J.R.: Thanks! I thinks so too, but still am experimenting with other networks to get it more detailed. Some progress has been made…

@Blake00: Hehe, then I have reached my goal

@Freestalker.fr: It is a way to start, but I think you could add some more fine details. Also the colour palette is a little bit boring but that can be improved easily. The white reflections look more like plastic, maybe you can change that for a start. Or is this just phong lighting? There are also some texture mapping problems where it gets blurred, but I think you noticed that. Can you send me your model along with the maps so that I can integrate loading them into the shaders of the wrapper?

Btw. I started a model viewer for your preview but realized my code can not load the TBN data for the normal maps etc, yet. I need the time available for the wrapper, so it has to wait.

In the meantime I fixed problems which prevented the wrapper running on Intel and Nvidia cards. I still have a weird error which causes FL to crash on undocking in nebulas/asteroid fields and which happens only on a Nvidia card. There are still some other issues, which might be related. But I am getting there

I think you should open a separate topic for it where we can discuss models using the (hopefully soon available) new features. Also, since there are currently not many people active anymore, expect it to take quite a while until people respond. I hope this changes with the release of the wrapper, but you never know.

Regarding the maps: It really is highly dependent on the lighting model. I currently use one of the often used GGX equations for PBR, but there are a lot of variations and different models with different parameters and different results. Also it often is a matter of taste. If you send me the model I’ll make you a video how I think it would look best and then you can make a decision. That is until I find a lighting model which I think is better and implement it (I am half serious here ;)) If you have roughness or smoothness parameters for your material/renderer try experimenting with the values. This also will make a difference - and also is highly dependent on the lighting model used.

Looks really nice! This is like I would have tried to make it look. If we get this into my wrapper it would look really good. The silver can made looking more like metal if you desire it, but we better tweak that with the real implementation of the wrapper.

Hehe, I am currently having the fight with matrices and coordinate systems again (don’t worry I am used to it). I converted code for PSSM/CSM (cascaded shadow maps) and the frustum culling it does for the different splits does not work correctly (as I was expecting). Worked at it till late night yesterday. At least it is integrated (which also took some time) and I only need to check out the math. Remember the difficulty that I don’t really have the game objects and have to keep track of them myself. Which is very very intricate.

There also is a really strange bug which happens only with Nvidia cards where it crashes when you undock. It even doesn’t crash while rendering, but after the frame was done somewhere in the FL exe, because some offset FL loads is zero, which I don’t even touch. Intel and AMD is fine…

I got access to the same graphics chip (it’s in my main desktop PC) and even some older hd4xxx mobile ones. Also some old AMD cards (mobile and desktop), so there will be plenty of testing on my side. The only thing I lack are Nvidia cards, where I only got one (970m). But I suppose this should be enough.

I can tell you that the hd4600 does not like compute heavy shaders. So expect to get worse graphics. I will try to include simpler lighting models so that very weak cards at least work. Currently if I switch to the HD530 in this laptop I don’t get much FPS. But it looks at least the same.

Sorry, while I understand that people want to test it themselves, I want to get rid of all bugs I currently am aware of first. Also I want to use it for our mod exclusively for a time period (we are talking about some few months) where I can further polish it. We are currently working on a mod update and this will be very fitting to be included. When I see that there are no unexpected side effects I will create a standalone mod on ModDB which can be used for mods and also works with vanilla FL.

After the short teaser image here is a video of the current state including the new shadows:

Edit: Here is another one.

So after some fixes and tweaks I am now at the graphics quality level I wanted to achieve. Only one feature is missing, which will even add more to the atmosphere, but I decided to add this after everything is working and maybe even after the initial release.

Here are two videos of the current state:

What’s left is getting the performance back again, as the shadows are tanking the fps (it’s not optimized yet) plus the remaining fixes. There also seem to be some glitches with the new shadows I need to figure out.

Feedback is as always welcome!

Skotty has asked for the same thing. The shadows are currently PCF filtered, but since the resolution is so good now it only has an antialiasing effect.

But shouldn’t be shadows in space only hard shadows anyway? The sun is so far away you basically get a point light and there is no atmosphere which scatters the light. This might be different in a nebula, though.

I will see if I can get a high poly model with good textures somewhere. The problem is ideally it also hast height maps since otherwise the self shadowing of the textures does not work. So it would have to use real geometry to make up for this.

@eigos: You’ll have to wait a little bit more, but good to know there is nothing in the videos you find unfitting or something like that
