Great to see another fan of Rodney Matthews’ goblin-eating toadstools 
There are no references online that I can find, but the original appears in the “Countdown to Millennium” book…
Thanks to ilusiondigital, Strannik, cosmic_fool, Zork, monstermaker and AztecSolja for comments.
Houdini: four pass rendering means that you render four different images (different shader and/or different Light)
and then compose these images in a composing package like Photoshop.
spasmodic_cheese: sorry, in the moment I have no time to make an indepth tutorial. But I keep it in mind.
NLightUK: You have right, I am a great fan from RM and I think I have all his books. And from time to time I take a look.
But during the work on the fungus I haven’t see any picture from RM. Maybe it was in my mind. I hope I’m far enough away
with my fungus, if not, it’s only a fun work not for commercial use.

Was simply pleased to see such a great rendition of one of my favorite Rodney Matthews critters! 
I’d love to see 3 of them together, surrounded by broken goblin weapons and skeletal remains, as in the original composition by RM…maybe a project for when you get another spare moment!
FYI - the only thing I noticed different in your version is that yours has no little arms to grab the unwary goblin! Apart from that…super work - I keep meaning to recreate some of RM’s characters (such great design) but never seem to find the time.
Your posts (along with most of the forum’s membership!) continue to be an inspiration - thanks for sharing! 
BTW - the original is on pg 100 of “Countdown to Millennium” (not sure what the title was in german!)…part of “The Nasties” proposed TV series.

great image,well done
just beautiful!
how did you make the eyes look so real??
I think this an awesome pic, but I would try and keep the shine on the snail, but not his shell, and under the mushroom cap, but not on top, and about 40% on the stem.
Obviously your going for style, and not realism, but I think you could make it realistic without loosing any of the style. Even with the all that shine everywhere it still needs some contrast, and that would add a little realism, and contrast all in one shot IMHO. Although I’d try, and keep the eyes, and teeth nice and shinny I think.
Great job nevertheless. 
Great work, impressive!
Have you thought of animating this character? It would be very impressive/magic to see it/him move!
Again, great work!
really cool
He looks a little evil, and the snake is the personified stupid meal
very cool 
:)
Hi Stumpf,
That mushroom is cool … I really like the eyeballs! But tell me one thing, is he Magic by any chance!?? 
Keep up the good work!!
Cheers,
Kev
Weyvin,
that mushroom might not be but
Stumpf + Zbrush = Pure Magic!!
without doubt
