Dynamic Lighting Question!!!

I am wondering...
Are the dynamic lights in Irrlicht harware lights... or software lights???
Thanks

Hardware.

Thanks for the info.

I wish they were software lights.

Then use the software renderer...

LOL, that would be rediculous.

I wish that the DX9 renderer had software dynamic lights so that we don't have the 8 light harware limitation.

8 hardware lights at one time=fairly slow as it is. Think about more than 8 software lights. That's rediculous. If you really need more than 8 lights, and will be running on fast hardware, then do lighting on a shader. Can have as many dynamic lights as you want and will be a heck of a lot faster than software lighting

I already did a test implementation with more than 8 lights in a huge Irrlicht scene. Actually it were about 500 lights. It worked quite fast, and when I have time, I think I'm going to add this as new feature to Irrlicht.

That's awsome!

Isn't the 8 light limit only meant per object? So you can have as many lights in the scene as you want, but only the 8 nearest to a mesh matter. And this should suffice for almost all needs, since the difference between 8 or 9 lights is neglectable for most cases.

Agreed! I think this is one of the most valuable sorts of features an engine like Irrlicht can have -- relieving you a bit from the limitations of the hardware and abstracting the details of implementation giving you a more orthogonal interface.

No. This is a hardware limitation.
You can only have 8 lights rendering at the same time even if you cannot see them in the level.
The only fix for this right now is to toggle on/off the lights depending on distance.

Awesome man!
