Cobwebs

[Springheel]

I decided to make a few cobweb decals since people have been requesting them. I've come up with something that I think looks pretty decent, but there's a problem. When applying it to a brush, it is mirrored on the front and back, so when you look at it, it appears to be on the right corner, but when you walk through it and turn around, it *still* looks like it's on the right corner (when it should now be on the left).

 

 

Is there any kind of shader keyword that can help in this case? I don't know much about decals. In a pinch I could apply them to models and mirror the uvmap, but that's not as flexible for mappers when it comes to size.

[Springheel]

Ah, I found a solution. You just apply the decal to one *face* of the brush. Once I added twosided to the shader it seems to work properly.

It looks really good Glad you worked it out.

You could also apply the decal to a patch, as this can be more freely bent and shaped.

 

Is the cobweb affected by lighting?

[OrbWeaver]

For a realistic spiderweb you might consider using a very gentle diffuse, but a very high specular. This means that you can see it best when the light is glinting off it, not when you look at it directly.

[Domarius]

That would be interesting to see.

[Springheel]

Yeah, I considered that for fresh spiderwebs. The one above is actually an additive blend, so it doesn't interact with light, but it has a slight transparency that helps it look believable.

[Springheel]

Ok, I've uploaded six spiderweb decals of various types (3 shown below). With flipping, resizing, etc, there should be lots of variety.

 

Feel free to play around with the shaders if you like, but they'll need to included an add blend because they have black backgrounds.

These are very cool, they will sure come in handy.

Hooray! Will check them out. Are they hand drawn or from photos? I did more searching yesterday and found a couple of good candidates; the problem was that both of them had copyright notices right on the image. If they're hand drawn, I think that's out of my ability range. I wonder though -- could a fractals program make decent ones? Hmm...

 

Dunno why I get so excited about simple cobwebs being in game, but I do.

[Springheel]

They're all taken from photos and then hand-tweaked.

They add a lot of atmosphere! These ones are a nice variety too.
