VRay-Displaced Ghoul

[yeohyip]

Hi everyone,

I've been looking at a lot of cool Z-Brush images and wondered what I could do with just VRay and Photoshop.



It's a character from a personal project I'm working on, tell me what you think (is it scary at all?).

The displacement map uses black for the deep cuts and wrinkles, and white for the high wrinkles. Grey is the middle point. Minute details are bump-mapped.

I also used a very subtle skin shader I've been working on to look right and render fast. I'll need to adjust it to the new build, but here's a quick render of it on a human, 1 spot + skylight. Both images have a low glow applied in PS.



Looking forward to any comments.

Regards,
Yi-Piao

wow great work man! mucho respecto. Care to share your skin settings on that woman?

[lukx]

this Ghoul is really, really nice, especialy it's mouth!

Wow, you are really talented Yi-Piao!

I'd like to see some exposed (vray displaced) brain on him

Really great work!

Woooow, very very nice. I love that Ghoul. He's scary indeed! (can we see some higher rez?)
I love how ZBrush and Vray work together (VrayBMPFilter + Displacement)
What's your experience with a more complex example like this?
Will you leave it with a Face or will he get a Body too?

That women looks cool too. How did you do the Shader? Fallofs? Glossies? SSS? If SSS, how did you got it fast?

Great work yeohyip, please keep on posting stuff like that!

Thanks guys!

The ghoul will get some sparsely scattered frizzy hair to finish it off, but I want to complete the body first. So yes, it's going to be a full character, and there'll be many of them in the final animation (hundreds maybe?). Oh, I gotta fix the eyes too (not organic enough)!

Geddart: Actually I didn't use Z-Brush. I've been watching the Z-Brush videos and stuff, tried the old demo, I really like how it works. But I can't afford it yet though.... so I took the lower tech approach, paint the displace in Photoshop, render to check, back and forth.

The displacements render quite fast without GI, about 2 min. per headshot. With GI it jumps to 15 min, but I suspect the new build will make it faster. I'm just a little afraid to try it at the moment since it took quite long to settle on the skin settings. A high res version is being rendered right now, it'll take awhile. So until then, here are some skin settings!

http://www.collective-expressions.co...skin_basic.jpg

The basic concept is to mask a non scattering material (the top epidermis layer) with a scattering one (the lower dermis layer). A lot of the blending between the two is based on Stahlberg's skin tutorial, and is done with a shadow/light falloff map.

Keep in mind this material has a very shallow scatter. For the ears and stuff, a more scattered one will have to be made and blended in on thinner parts of the mesh with a mask. Also, it's far from a one material fit all solution... and I haven't really tested it with diffuse maps put in yet, just flat color or procedurals. If you're getting "dirt" on it, the refract interpolation needs to be upped, this may happen on distance shots on high detail models. Hope you find it useful!

EDIT: Forgot to add, I'm not sure how these settings work on 1.46.12, I'm still on .10 at the moment (might skipover .12 in fact due to the blotches reported in the other thread).

Very impressive. That ghoul is damn spooky.

Yeah you should really share your girl skin settings

that's really great work. I especially like the scratch detail around th ears and the separation you were able to achieve with between the skin and the bloody parts.

Only Photoshop?!? Gosh, that makes it even more impressive!

The Skinshader looks very interesting. I will try it when i have time.
Keep it up!

Nice job, the nose looks like what's called cauliflower ear that happens to boxers when they get hit in the ear too much.

Thanks everyone! I'm glad you find him scary/spooky, I was continuously comparing with pics from the Excorcist, which seemed to be 10x scarier! Or maybe I've been staring too long at this guy.

Don't forget to give credit to VRay's displacement! The shift setting on the displacementMod gave me the idea for it in the first place. The biggest problem was handling the displacement across UV seams. I had to go full displacement or none at all across them, but it worked out quite well. I'm quite bad at polymodelling (especially for details), so I think this will be my modelling method until I get Z-Brush... But it's still quite fun!

I will post more as soon as I finish the body, it's gonna take awhile with toes/fingers etc!

What an awesome character - you need to work in Hollywood.
