Holes/Slits in faces of model

[Double Doppler]

I have started on a new geometry for my model at the basic stage, in an external program. I exported it to .3ds format, imported it in Oxygen and ran the viewer. I noticed some wierd effect on the faces of my model - like holes, or slits as you might call them, interuppting with the dynamic shadow effect. Here are some pictures of it:

Why is this happening? What can I do to stop it?
All helpful feedback appreciated.

Nothing is wrong with your model, AFAIK.

I've never had this particular thing going on because I usually have a fully complete LOD set with mats and all that stuff when I move to O2, but I've seen it on other peoples' WIP screens. I believe it's from not having a shadow LOD and / or UVs and / or materials.

I think perhaps, since you have no shadow LOD, the engine is using that same LOD as the shadowLOD, and so you're having some kind of z buffer problem with the shadow volume. Try turning shadows off in buldozer or adding a named property to that LOD called LODnoshadow with a value of 1.

Turning off shadows won't make a difference, basicly bulldozer is using the object you have to draw it's own shadow. Once you pass a certain polycount it will no longer do so, it looks strange because low poly shadows are always drawn with the "high" setting, the fuzzy shadow which looks very strange on a model with no material. You need not fret, just keep building the model and eventually it will vanish.

Also you may want to try copying and pasting the model piece twice into the scene, if it exceeds the draw count then the shadow should vanish.

EDIT:

Nvm I got it utterly wrong.
