Surface Noise in zbrush???

razzta91

Hallo

Im playing around with zbrush, and I have a question:

I have a model and I use surface noise on the model and it looks nice, but when I export it to 3ds max the "niceness" is gone and it just look like the model I imported to zbrush.

What to do?

can you show screens? how are you exporting?

you need to press the apply to mesh button if you want it applied to the mesh itself

I dont know what to show I just click the export button in zbrush and then choose obj.

Okay, I will try that, thanks

It dosent work, just to click apply to mesh?

have you subdivided the mesh atleast a few times? applying surface noise to a low rez object won't have much effect, it doesn't have the polys needed.

i've been playing around surface noise effects in Zbrush recently, I can get some pretty awesome results for my Ztools, and yeah you have to sub devide a lot then click 'apply to mesh' to save the noise. But to be truthfully honest the noise is often lost when baked down to the normal map. I'm starting to think 9 times out of 10 you'd get a better result with that kind of stuff with normal map filters in photoshop....

Definitely something to think about. You're only going to get so much detail from a game res texture so knowing when to stop is key.

Okay, when I click apply to mesh, the mesh is looking weird, it looks like there are bubbles on it?

Could you show some screenshots?

I find a good way to apply noise is to create a new layer, apply the noise to the mesh, and then adjust the layer intensity. It tends to get applied pretty strongly for me.

You could also save off a morph target before applying so you can paint it out where you don't want it.

That's just how it is. What you see in the preview is I believe a 2.5
representation of the noise, so when you apply it differs.

Save a morph target apply the noise, adjust the displacement.

Edit: too late apparently

bear in mind that your topology of your mesh is going to effect how the surface noise is placed down, if you've got long thin tri's its gonna effect the 'rythm' of your noise. Maybe dynamesh it before you bake it down?

I tried what |MM|said and it works!!! thanks for all the suggestions
