So I'm getting some bad looking seams in my lighting. One brush in shadow, one next to in in light.

How can I get rid of this? Screenshot to demonstrate:

They are at different angles, I thought you meant two brushes on the same plane. This looks normal. If you want to change it, change the shadowed one's declination.

This is how light works. a light_environnement points in one direction, its like a huge global spotlight, and it's not an omni light, so differently facing angles will receive different amounts of light. If you want it to be all the same, then why are you running vrad anyway?
To smooth this out I'd increase the power in the displacement.

Uh..I'm aware of how light works. I'm talking about the ugly SEAM that you can see in the screenshot, where there is no transition of light levels, just two levels of light side by side.

Here's my guess. The two faces aren't in the same smoothing group. This is because the angle between the two faces is too extreme. In most modeling programs you can override this and set them to the same smoothing group (which may end up looking bad), or you can change the angle at which the program automatically places two adjacent faces in the same smoothing group. In Hammer, you have the Smoothing Groups box accessible from the Face Edit Sheet (Shift+A). However, I don't think it applies to the faces of a displacement. I imagine they are automatically smoothed as mentioned above. I don't know if you can change the angle in Hammer, but I imagine not.

So I'm thinking you have to change the angle so it's not so extreme, adding more faces to do so if you like.

And I could be wrong about all of the above. :)

Yea, decreasing the angle or making it all into one brush seems to be the best choice.

Oh, wait, those are two different displacements. You could probably do the smoothing group thing and it may work. Don't ask me how exactly to do the smoothing groups, though. I don't know. :)

Are you a mapper?

Lol, no. Don't listen to me. I've yet to make a map but I know a few things here and there and I can make some assumptions, for better or for worse. :cool:

Yeah, cause I can't find any smoothing options or anything like that.

edit: oh wait nevermind...okay, I'll play around with those options...

lol I dont know what I'm supposed to do.

Hey, it sounded convincing. :D

Check the wiki maybe.

Thanks.

Doesn't seem to be working...

im having the same problem on my current WIP. two different brushes, but both are straight (horizontal). it seems the shadow of the building is registering on one brush, but not the other. i havent looked into it at all though, bc its not my priority yet
