Hydrax 0.5 and caelum 0.4

Hi all
I am new to this forum, and I am currently trying to integrate Hydrax 0.5 and Caelum 0.4 in my project.
But I have some important limitations, I would like to know if solutions exist.

- Is it impossible to mix caelum (ground fog) or ogre fog with hydrax ? I really need fog in my application... (just waiting for this topic too http://ogre3d.org/addonforums/viewtopic.php?f=20&t=9480...)

- When I create a depth composer object with caelum, this assert happens void DepthRenderer::update()
{
...
assert(oldCameraViewport == getMasterViewport()); is there a solution for that ?

- Running in debug mode with hydrax is very slow, (XP, Quad core 2.4 Ghz, 8800 GTX), have you got this probleme too ? is it normal ?

- I cannot run Hydrax with OpenGL, I have an ogre exception:
OGRE EXCEPTION(2:InvalidParametersException): Named constants have not been initialised, perhaps a compile error. in GpuProgramParameters::_findNamedConstantDefinition at f:\codingextra\ogre\shoggoth_vc9\ogre\ogremain\src\ogregpuprogram.cpp (line 1087)
I think that GLSL shaders are missing, so is it planned to make Hydrax compatible with OpenGL in future version ? does another solution exist ?

thx for your answers

I have yet to find a solution to the fog problem. Not only that, But there is another bug whereby, with caelum enabled, the water seems tooooooo transparent. Like when i place my camera so it can look from "under" a wave, The wave appears not to be there, due to this extreme transparency. When i use a standard skybox, This transparency problem does not occour. Im hoping that when skyx is released, These problems will go. If not, I may have to develop my own system, which is a pitty.

Cheers

at last !! thanx a lot for your answer ! ^^
for the fog problem, I want to write fog shader then try to apply it on the whole scene with a compositor, didn't have the time to implement it yet...( well that is also a "pity" to implement own fog...)
About your transparency pb, sorry but I cannot help you, but I may have a look and try this bug.
I am also waiting for skyx, it looks great,I just hope that it will work with hydra better than caelum does!
I am very disappointed about this forum, I did'nt have any answers

@scratchyrice - did you see my post viewtopic.php?f=20&t=9480

(D/W)M_Technique_Pass0->setFog(true, Ogre::FOG_NONE);

Add that to all techniques in Hydrax's MaterialManager.cpp

Also, I know what you mean about the transparency. You don't quite know when the water starts and where it ends...

@ DanielSefton - Indeed, I did. However, This is a good solution, Except it completely disables fog on the water, Which is a bit of a bummer lol.

@DanielSefton
lol why didn't you help me ???
I saw your answer and Iceman1540 is still waiting for you in your thread...
"you can elaborate a little, I'm trying to get fog working also.
Thanks in advance."

same

Because atm with fog enabled the hydrax water plane does not react to camera distance, it is always fogged no matter where i am.
That's how Hydrax works. It's a projective plane - it's basically infinite according to your camera position. The fog isn't going to budge.

I was just @ing scratchyrice because he asked the same question, and I was wondering if he'd solved it. I helped you too by posting the solution...

It's not rocket science.

Underneath wherever WM_Technique_Pass0 or DM_Technique_Pass0 is declared, add ->setFog(true, Ogre::FOG_NONE); - I don't know how I can explain it any better.

@DanielSefton
Thank you, I understand now. I didn't know what (D/W) was.
Its clear now.
