Ocean shader draws black water

Hi guys,

I tried to implement the water from the ocean demo into my current project and now I have the problem that the water is black, looking like an ocean of tar, no texture showing (should be the skybox texture). I first thought of some missing resources or something, but the shader is loaded correctly (water surface is moving) and the skybox is showing (so the needed skybox textures should be found, too). Ogre log doesn't show any errors. I experimented with the original ocean demo and tested how it would behave if I delete some of the resources, etc. but did not find a clue (the ocean never turns black). It would be a bit complicated to show the actual code from my project because I'd have to rip out all needed parts out of a 40k+ lines project and so I ask quite general:

Does anybody of the shader pros around here have an idea why the water is complete black? Did anybody have a similar problem in the past?

Regards
MAC

Sounds like your using the example Idle posted a while back. Have you changed anything in the shaders or scripts?
Could you post a screenshot of the water?

Yes, I think it's the one from Idle. I didn't change anything in the shaders or scripts. I just made a small video of what it looks like:

As you can see the water is moving and the skybox is showing, too.

When I get some spare time I'll try to replicate the problem. I'll let you know if I find anything.

Yes, Idle, you're demo always works like a charme. I tried to harm it, but no chance! :D

The Ogre.log doesn't give any errors and the only difference between the log of my project and the log of your demo is the following:

From my project:

I don't know what this means and if this has something to do with my problem.

Got it! The water turns black if you use WorldShadow(#PB_Shadow_Additive). With all other shadow types the water is drawn correctly. Since additive shadow is the only one I can get to work (the others are ugly (modulative) or don't show any shadow at all (texture additive)), this is very frustrating. Do you know why the ocean shader doesn't like additive shadows?

I'm not sure why they don't work, but I'm guessing it has something to do with how additive shadows are rendered.
I've seen several other shaders have issues with additive stencil shadows as well. I've heard additive shadows have issues
with static light, but that might be unrelated.
the others are ugly (modulative) or don't show any shadow at all (texture additive))
How are modulative shadows ugly?
Texture additive shadows won't work until you specify which entities will receive shadows and which ones will cast them.

Here is another video showing the differences between the three shadow types in my island scene. I have a directional light working as a sunlight and a spotlight shining straight down to the middle of the island. With additive shadows on the shadows of both light sources are rendered as expected, with modulative shadows on, the shadows of the spotlight are totally wrong, modulative shadows are not working with spotlights. And with texture additive there are no shadows. I don't know how to specify if entities should cast or receive shadows. The only ways I know to set shadow properties of lights and entities are: EntityRenderMode() for entities and DisableLightShadow() for lights.

Is that island an entity or a terrain? If it's an entity you can use EntityRenderMode(#Island, 0) to make it receive textureadditive shadows.

I see the opposite of what your seeing.
I watched your video and it seems like modulative shadows are rendering correctly, but the additive are not. The modulative is rendering the shadows from both
lights whereas the additive is only rendering the directional light's shadows.

Here's some example code. Check out both modulative and additive shadow types.

Wow, that is some kind of funny stuff. The shadow types in my program are flipped somehow. In the example you posted they work the opposite like you said. I just double checked the usage of shadow constants in my code and they are ok, as far as I can see. I'll have a deeper look later.

All entities in my island scene are meshes. I set the render mode to 0 and have texture shadows now, but they are really ugly and are offset (see markers). Also only the shadows of the directional light are rendered, the spot light is ignored:

This is what modulative looks like in my program (which obviously is additive, like you mentioned right). The problem with this is that the shadows of the spot light are rendered where the light does not shine (market with arrows in the screenshot). The light shines to the area that is marked with the circle:

And this is additive in my program (which should be modulative). The light is fading out of the spot light range, everything is looking beautiful, but in that mode the ocean is made of tar:

Ok, guys, now it works like I wanted it to work. Additive shadows + ocean shader. And it was very simple to achieve: DisableMaterialLighting(OceanMaterial,#True) did the trick! I also added "receive_shadows off" to the ocean.material file but I don't know if has something to do with it. Thanks for all your replies. I'm a happy person now (until I get to the next problem... :D )
