Hey peeps.

Here's a screenshot of a level in a game I'm attempting to build.
Now, I don't know if it's because I've been drinking tonight and got my beer goggles on or if it's the dark pro render engine, or if somehow, somewhere I need to add/change a bit of code (i'm assuming its the latter) but where I've crudely marked (with the blue arrows) can you see that the level abruptly "blurs"?
Is there anyway I can stop this so that the level appears sharper and cleaner?

You can fix that by enabling anisotropic filtering. There's a plug-in available that makes it possible to enable this in DBPro. You can find it here.

Some other options are to try using the ,1 flag when getting or loading images - this usually stops mipmapping.

I would see how the filter plugin goes, and also try setting the object mipmapping to nothings:
SET OBJECT TEXTURE Obj,1,0

The ,0 at the end tells the object not to use mipmapping, the ,1 flag sets the texture repeat mode (wraparound, mirror etc).

Yup this is rather a mipmapping issue...

Kaedroho's Anisotropic filter improves a little on removing mipmapping in my opinion and it runs really fast. I noticed little or no impact on framerate when I tried it, but removing mipmapping for objects is easier I guess.

I guess it depend what kind of level of texture detail you want visible at all times.

It's not always a good idea to remove mipmapping. Mipmapping removes the annoying "shimmering" effect you get with certain textures when you move the camera. The best thing to do is try both options and see which looks best. A more complicated solution is to use a shader where you can control the mipmapping, e.g. by increasing the distance before each mipmap is used.

If you want to take control over the mipmapping, then a good option is to use a .DDS plugin, theres one for Photoshop and PaintShopPro9. That would let you define the number of mipmap images, how they are compressed and laid out. Then save your images as .DDS, and when you load them up, they have the mipmapping already calculated.

Disabling it can produce some horrible jaggies and shimmering, especially with a high contrast texture, like the grids there. At least there are options to get rid of the problem, take control of mips, make the lines thicker and disable mips, use anisophalic blending... lots to experiment with.

I didn't know you could do that. Sounds useful. Something else to experiment with. Thanks.
