PCF 7x7 / 5x5 / 3x3 / 2x2

If you are interested in a sample, try here:

It's for XNA but was super easy to get to work in DirectX, if you need help tell me :)

Thanks, but actually Ogre handles the setup of the shadow frustum for cascaded shadow maps. I might use PCF for the soft edges, but I think I probably won't need to use depth tested shadows (for self-shadowing) so I can probably get away with just blurring the shadow map.

yay ;)

Wanna know the really cool part? it can sync online too as I edit it.

Gotta boost the speed somehow though.

Very nice! Looks like Havok has some nice debugging tools too.

So can you have multiple users editing the volume at the same time, for example? That would be cool :-)

The speed when editing online, or the speed in general?

Nah, updating the Havok mesh causes a performance hit for some reason, need to look into it. I only just started with Havok.

Ah, ok. When working with Bullet I had a volume of about 256x256x64 voxels (the castle in the video on the front page). It was broken up into chunks so that I only had to update the parts that had changed. It was working in realtime but I don't think I could have made the volume much larger... after that it would be time to look into LOD maybe.

Yes, my volume is in chunks. right now 64x64x64, but I think it is a bit too slow updating that as well. How big were your chunks? I can try.

Problem is I am also worried for having too many draw calls for the terrain alone if I keep getting more chunks as I get the size smaller.

Another thing to keep in mind is that without Havok, the chunk update (even 64x256x64) was pretty much instant.

I have to say I don't remember how big my chunks were. I would guess 32x32x32 but I can't be sure.

You might also want to consider having a different chunk size for the physics compared to the graphics? Either you could run the surface extractor more than once, or you could combine several small meshes into a bigger one?

I need to look into it, it is a bit complicated right now considering that everything is represented as an entity. I will see :)

So what post processing effects MLE has?
HDR (Tone Mapping + Light Adaption + Bloom + Star Effect)
Depth of Field
Screen Space Ambient Occlusion
Cascaded Shadow Mapping
