I have a skin-tight costume  (basically a texture for the V4 catsuit) and I'd like to create a scene where the character wearing it has suffered an injury from a sharpened weapon (or a claw).

What is in your opinion the best method to create a realistic tear in the fabric?
For the actual hole I can simply apply a transmap to the material, but is there a way to simulate what happens on the edges? Loose fabric threads, ragged and lifted contours, and so on?

Probably a bump or displacement map will be best.

Still or animation?

Definitely still. I want to show the final result, not the actual ripping.

If it's a matter of having ripped flaps hanging from the outfit if may be just as easy to model the rips in your modeller and parent them to the outfit as is needed.  Now, I've never done anything like that, but seems lie an easy way to go about doing it.

If you look in the RMP, Ravynsworld has a set of brushes with edge tears, use those to make a transmap in Photoshop or whatever, job done!!

I'm probably doing it wrong, but the one time I tried to import something with a hole in it into Poser, it filled the hole...;)

probably texture it in, I s'pose.. see above entries for better explanation...

If it's a still I'd do like thefixer says and postwork the rips in.

I'd do a render with the clothes showing, then do a second render with the clothes hidden.

Then in a 2d editor bring in both the renders... have the clothed render on top and nude render as background... then using a tattered/ripped brush I'd erase the clothes layer as I wanted.... the nude background keeps the skin underneath.

*Not what I meant, it'll look crap in post. You make a transmap in Photoshop and add it inside Poser, there's a tute on my web site for doing exactly this if you want to snag it!

Transmap + bumpmaps will give you very decent results. Above is a a quick preview of one of the textures I'm making with rips tears and frays in it. Careful transmapping is doing most of the 'work' here.

here's a closeup :)

Made by the same method TheFixer is suggesting here.

For comparison, this is the hat before transmaps.

Very cool :)

On the other hand, modelled rips + cloth simulation can work well too. :)

What I mean is this... take a full render of a person clothed

and take a render of them without clothes... or without the clothes you want ripped

and use the eraser with a tattered brush or chainmail rounded brush to achieve the effect within 30 minutes like I just did... with no transmapping... but transmapping is better if you're doing a series of shots and want the rip to remain similar in all shots... if it's a single shot... I'm saying you have options

The "two renders" method will give you the holes, but not as good as a transmap will (unless you paint in shadow effects). And even with the transmap method you'll still have to paint in the tatters and loose flaps of cloth.
I'd go for the dynamic cloth pathway, plus transmapping. That'll give you rips and tatters, including correct shadows.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
