This definitely needs review as I'm recursively removing flags from the model after recursively setting them. (This sounds odd, but I didn't see any direct means of enabling the flag to begin with, so it didn't appear to be a matter of just not enabling the flag MODELFLAG_CASTSHADOWS)

I forgot to mention that the model still receives shadows -- I couldn't figure out where this was being set, or rather, where it could be unset from.

There are a few problems in the patch:
- In the new
CModel::RemoveFlagsRecfunction, you are checking if theMODELFLAG_IGNORE_LOSflag is being removed, but then ignore LOS, where I think it should be doing the opposite (not ignoring LOS) - In
CCmpVisualActor::InitModel, where you are setting material defines, I think those are only going to apply to the parent model, not to all the sub-models recursively (e.g. props) - Also there's no reason to set modelFlags to 0 before adding the flag, in fact, there's no need to use the variable at all, it can be passed directly into
RemoveFlagsRec
However, because it's not only flags that need to be recursively removed but also materials that need to be defined, I have modified the original patch to use a CModel::RemoveShadowsRec function instead. This patch seems to work, except the decal on some preview models still receives a shadow, which is slightly annoying.

So, I was able to remove the decal shadows by modifying the terrain shaders slightly (they didn't support the DISABLE_RECEIVE_SHADOWS definition), and decal-only models like fields needed a special case.
Preview entities don't really exist in the game, so it makes little sense for them to have shadows. They also cause ugly artifacts. It seems better for them to neither cast nor receive shadows.
