Poles not producing shadows

I have alot of small poles in my map that are just 4 sided cylinders 4x4 I think. It looks like they are producing inverse shadows or something like that. I am only running RAD on normal, does that have anything to do with it? The texture on the pole is cable_red.

As you can see in the picture on the middle left of the screen it loks like some sort of shadow is being produced. The env_light is coming from the right side of the screen set to -60 degrees or so.

Also if anyone knows what causes these things that look like cuts in walls, sometimes looks like white dotted lines, that would be nice to know.

Thank you for any help.

Looks like a result of face splitting. Make these poles func_details
(or func_wall, whatever you want) and see if that solves the problem.

As for the second thing, you should zoom in on the 'cuts', I can barely see anything strange there.

The poles are not func_wall's so they are slitting the surface. When 2 world brushes meet, they split. Same when 2 entity brushes meet, they split.

However, entites are invisible to the engine, meanning they cannot be used as vis blockers nor are they visible to the lighting engine. This means, they will not produce a shadow.

So you can either go with facespliting or no shadows. WRONG. Go with neither.

Create a 1 unit high brush that touches the floor. Make it a func_wall. Next, put your pole starting on top of that brush. Dont make it an entity.

This way, the 1 unit high brush will prevent facespliting, but it wont cast a shadow. However, the pole will cast a shadow, but because it sits atop the func_wall brush, it wont create face spliting. Another technique is to simply raise your pole 1 unit off the ground. But this leaves a gap that can be noticable in-game.

Shouldn't there be an opaque option to choose?

one question per thread please.

If you want to fix the problem easily, dont have the poles rotated 45
degrees. Keep them axis-aligned, and the shadow problem should go away.

What are those poles, are they a brush or model?

Model check the options for disable shadows, it should be set to "no"

If its a brush: Is it a world brush? The should be no problem
Is it a func_anything? Make sure you have the right opaque setting..... like spartin said. (I forget what you put in the value)

what this really is, is that your lightmap scale is to high
for something that small to cast a noticable shadow. at first a made
this map with lightmap scale on the textures at the default 16, but
these screens were taken with a lightmap scale of 4. they clearly show
that a func_detail casts a shadow, but func_walls, func_doors and
func_breakables dont.the third also shows how entities dont cut world brushes, but
world brushes cut eachother, like wild card said.(that 1 unit func_wall
thing is a good idea, btw)

/edit

now you can slap me... someone told me how to do links on my first post
ever and fixed my thumbnails(thanks btw), but i just didnt put 2 and 2
together...

/edit

okay, no screens for now. the links work, its just my host thinks they
have restricted access. btw, if anyone could tell me how to post a
download it would be much appreciated and they would recieve many
points(not snarkmarks, i cant give those) and perhaps a gold star(not
one for the elephant, i just had to get rid of that one)

I wasn't asking a question just merely stating that he should try checking for an opaque option.

Spartan, I think he was referring to my two questions in the first post. I will take more screens and make another topic for it.

EDIT: Also how would I go around changing the light map scale value?

its in the texture application tool.
