Stunt Rally - version 2.7

duststorm · Post by **duststorm** » Thu May 23, 2013 2:19 am

The tracks look gorgeous! I notice you added new tree models.
There's quite a lot of objects in view, are you using batching or impostering for them?

Happy to see that the project is still alive. Keep it up!

Crystal Hammer · Post by **Crystal Hammer** » Thu May 23, 2013 6:52 am

Thanks.
I still use Paged Geometry with impostors. It's quite a challenge to tweak it, because with too big page size you'll see lag when pages load (they are made on CPU), and with too low page size there is too many batches. Also view range is best to be far, since you can see switching from impostors to 3d models, but higher range also makes more visible triangles.
We have a modified code for paged-geom, also fixed some issues. Still, great code, too bad it's not developed now.
I once tried Hardware Instancing, I want to try it again. Not sure why it had a bit less Fps than paged-geom. But there was no lag at all, and no need for pages.
I need to use instancing for static objects too (rocks, temples, etc). Since now each one is a new batch.
Batch count is crucial, needs to be as low as possible. Also shadows, and effects are a Fps killer.

We have a new release 2.1.
Quite big changelog http://code.google.com/p/vdrift-ogre/wi ... ionHistory
Car steering issue should be fixed now.
We now use SDL2 for window creating and input.
New screenshots here https://picasaweb.google.com/1179173831 ... RallyVer21
And few new editor videos http://code.google.com/p/vdrift-ogre/wiki/TrackEditor (from chapter 11 and above).
Check our home page for other links http://code.google.com/p/vdrift-ogre
e.g. our Forum and simple online Track and Car browsers.

New version 2.2 is out.
Our forum post with links: here.
Biggest new feature is the new Challenges game mode, for those who already know how to drive and want a challenge.
Also new Hud layout in game. Time difference shown and points updated now on each checkpoint, lap results window appears on right.
Many changes with Gui and inside editor.
Screeshots gallery for this version: here.
Btw. I'm developing alone, so anyone wanting to help is welcomed. Especially somebody who could fix shadows

See the bottom of our Readme.txt for more info, can be viewed in game and here.

I'm trying out the game, it looks great. But even after I carefully built Ogre, mygui, and Stunt Rally from source, I'm getting a null pointer dereference.

(This appears to be an Ogre bug. I tried Ogre 1.8 and 1.9 - both have the same problem.)

Steps to reproduce:
1. start stuntrally
2. select Options
3. set Graphics to Lowest
4. back
5. quit
6. start stuntrally
7. select Tutorial
8. select Tutorial Basic
9. select Start
10. it loads all the way to 100%, then crashes

I'm using:
Stunt Rally from git head
mygui 3.2.0
Ogre v1-9 from sinbad's repo
fglrx 13.9, AMD A10-6800K with Radeon HD 8670D

Here is the segfault:

I don't know how, but fglrx is getting a null pointer in rax and then attempting to dereference it. This might be a vertex/index buffer problem.

Edit: Even after switching GPUs, with a Radeon HD 7970, it behaves exactly the same.

Crystal Hammer · Post by **Crystal Hammer** » Tue Nov 26, 2013 10:12 am

This looks for me like the driver is crashing /usr/lib64/dri/fglrx_dri.so
Maybe other drivers would work ?
Does it happen on any track, eg. Try loading Test2-Asphalt or Test4-TerrainBig or dirt3 they are pretty empty. Try also turning off all effects or just trying Low preset maybe. Does the linux binary crash this way too ?

cord · Post by **cord** » Wed Nov 27, 2013 5:17 pm

The tracks helped!

I can play most tracks. Tutorial Basic is one that leads to the crash. Still, thank you, I'm just trying the game out and it's awesome!

I have a Microsoft Sidewinder (cheapo joystick) and it works on most open source games. I did download the binary 2.2 version but I can't seem to get my joystick to work. I'm looking into the code to see what I can figure out.

Crystal Hammer · Post by **Crystal Hammer** » Fri Nov 29, 2013 5:54 pm

We released 2.2.1, the 2.2 version has a bug and crashes on some tracks with pipes.

Crystal Hammer · Post by **Crystal Hammer** » Sun May 11, 2014 7:55 pm

We released version 2.3. All tracks look improved.
See our post here:
http://forum.freegamedev.net/viewtopic.php?f=81&t=5507
There is a new game video here:
http://www.youtube.com/watch?v=s714RoTFF38

We replaced all terrain textures with new, bigger ones.
Their license is: CC0 (Public Domain). I uploaded them here, for convenience:
http://opengameart.org/content/terrain- ... t-rally-23
You can see how they look in gallery, http://picasaweb.google.com/CryHam/

A big update for editor this time. Now the terrain's blendmap is an RTT with shader.
This allows realtime update for any brush size and also made even Ogre's terrain editing faster (less stuff to compute on CPU), probably like 2x.
BTW also made blendmap noise with few parameters in shader, it's still fast.
I also moved to sum of all layers not lerp, in blendmap shader code. This allows blending between any of layers.
To reduce parameters on Gui, for each layer, there are blend and noise options to next (+1), previous (-1) and next (+2) layers.
Still terrain is 1 pass and 4 layers max.
In editor there is a test blendmap mode which clearly shows colors and usage of layers. But I didn't make a video for it yet.

Hi,

Just tried your game again after the new patch (version 2.3). Great work. I intend to try multiplayer with a mate soon.

I had a few issues (if you care).. System specs. Windows 7. AMD Phenom 2 X2 processor. AMD HD5830 video card. 2gb of RAM. I used the DirectX 9 renderer.

If I enable the 'depth of field' effect the screen doesn't update any more. The game still works fine, except the image on the screen stays as what it was just before I tick the "depth of field" button
The terrain wasn't textured, it was displaying as a black colour.The car, vegetation, skybox and road were textured and displaying fine. There were no obvious errors in the Ogre log that I could see (not an expert though). I tried all the graphical levels (lowests to ultra) and the terrain was affected at every stage. I also tried every combination under the material tab in the graphics options menu.
If I use the OpenGL renderer in windows, everything displays as white but shadows work so you can still make out the outline of things

I don't know if you have any suggestions to solve the terrain texture issue.

Thanks

Crystal Hammer · Post by **Crystal Hammer** » Tue May 20, 2014 10:08 pm

Thanks.
Strange. I don't know why. We had several issues with black terrain. But if nothing is in log then I got no idea.
- Could have a shader compilation error in log, or maybe something wrong with loading textures from disk (which I load directly from file path, source in ogre/common/PreviewTex.cpp).
- Effects are buggy (DoF too). I didn't know of your issue, maybe something in log about compiling errors.
- OpenGL on windows was abandoned, never fixed, it just looks like you said.

old_man_auz · Post by **old_man_auz** » Wed May 21, 2014 1:04 am

Here is a Stunt Rally 2.3 Ogre.log if you can see something that I can't. There were some texture exceptions, but they seem to be related to the vegetation system.

Hi,
I think you have mixed headers (Ogre 1.8 + 1.9) in your /usr/local. OgreOverlay.h should be in OGRE/Overlay/OgreOverlay.h not OGRE/OgreOverlay.h. The OGRE/OgreOverlay.h must be a leftover from Ogre 1.8 or an earlier version. I would remove the /usr/local/include/OGRE, reinstall Ogre 1.9 and try again.

How you make the car-capot dynamic cubemap shader? Is real Physic Based reflection?

Crystal Hammer · Post by **Crystal Hammer** » Fri Mar 04, 2016 9:37 pm

It's just a dynamic cubemap, so 6 render targets rendered (without shadows, and by default all 6 each frame).
It lags a bit, slows down fps of course, but has few options.
We use shiny for shaders.
We have fresnel too and that's about it.
