Other than that, I'd say it's a bug in your code.
Also, that fog bug I see int he pic which I just found is PROBABLY related to multitexturing.
Let's say you have fogging enabled.
And let's say that you have a plane with three textures on it.
Now let's say that your card only has TWO texture units, so Blitz cheats and renders one of the texture layers as an additional surface.
In this scenario, Blitz will render the scene incorrectly, because that second surface will ALSO receive fog, and so you will get 2x as much fog as normal.
The only way to prevent this, aside from petitioning Mark to fix the problem, ASSUMING IT'S POSSIBLE for him to fix it, is to always have HWMultiTexture False in your code, or make it an option for the user, OR ignore people with one texture unit, and presume that there will only ever be TWO texture units available, and manually create that third texture surface as another surface in your model so that Blitz won't try to do it improperly.
I could be wrong of course, Mark may have corrected the issue, but I had this problem a long time ago when doing terrains in Blitz, where I was getting a different fog color than expected.
