I created a cube.mdl and a plane.mdl in med. I put the cube above the plane in
Wed, and set the "shadow_stencil = on" variable before my main function and
then set the "my.shadow = on" in the cubes action.

In game, when I view the plane from a downward angle, I get the cubes stencil
shadow on the plane, but when I tilt the camera slightly up to hoizontal, the
shadow disappears even though it should still be in the view. I tilt it down
again, and the shadow comes back! What causes this strange clipping behavior?



The picture (right) shows a view slightly downward, you can see the shading on
the cube. However, as the camera tilts upward (left), the cubes shading and the
shadow on the plane has disappeared! I tried this with a dynamic light and/ or
sunlight, but it didnt help.

What am I doing wrong?

I don't think I know anymore than you do, but could it be the angle of the sun?

Thanks for the reply Domingo. I have tried different sun angles and even putting a dynamic light directly over the cube.

By the way, this is from commercial 6.314.

So you still have the problem? Maybe you need to create some kind of material like shadow?

I've the same problem, too. When I use shadow_stencil = on; , the shadows disappear sometimes. I don't think you can do anything against this, only waiting for the next update.

Maybe this is a bug.

dont take my word as gold. But I recently upgraded my vid card and am final able to use stencil_shadows myself. I encountered some what similliar problems too. I think it has something to do with the amount of polygons in the model. I was just reading a post the other day that said something along the lines of this. Havent tried it with higher poly models yet tho so could be way off here but prehaps it is the cause of the disappearing shadows. Tho i also know that there was some issues with stencil shadows aways back. Not sure if they were in the current version or not. So prehaps they have allready been fixed. If not that could also be the cause. Not sure if theres a work around or not try doing a search. If i come across anything ill post it here. Good luck

Thanks FeiHongJr, the plane in the picture was made in med, it has 2048 faces
but the cube has only 12.

Edit: I have experimented with several models of various poly counts and it
dosent seem to matter. It works fine on model to wed block, but not on model to
model.

I think this bug occours by everything without geometric forms, like cubes, spheres and so on.
