A bit of play: I thought to use the same vector displacement file as I used for the mud in the auroch image for some rocky outcrops, just x100. Added some square rocks (available on this forum) et voila. A bit over the top, but somehow I like it.
That looks awesome, Ulco!!! I have to say that I never tried vector displacement so far. Is there any tutorial or a thread with a description on how to use it?
Thanks Hannes. There are some threads about vdisp, but it's actually quite easy. In mudbox (for one) you can pull out shapes in a subdivided plane, the add a base lores plane, and have a (world space) vector displacement map extracted (calculates the difference). This is a 32-bit color tif or exr (mine was only 8Mb). Import it using an image map shader, set colors to 'are lineair', set a decent size and attach to a vector displacement shader. I only had to negate the Z for this to work properly (don't know why). Then set size of displacement. Etcetera...
These look like stone guardians. :) Wish I could do that sort of rocks...
Brilliant and fun!
I just wanted to ask what a lores plane is. Thank goodness my brain started working and I realized that you mean low resolution and not some mystical traditional knowledge plane :-[ :-[ :-[
Embarrassing...
Now I'll have to find out how to create a vdisplacement map in some other app, since I don't have Mudbox. Exploring the forum...
I don't know what other software can make these maps. I tried painting them in photoshop (RGB layers each with some blurry structure, set to 32-bit), but that's very primitive. This might interest you, just found it: https://support.solidangle.com/display/AFMUG/Vector+Displacement (https://support.solidangle.com/display/AFMUG/Vector+Displacement)
Thanks, Ulco! Very interesting! And there's a vdisplacement map for downloading I can play with. You'll see a lot of ears in the near future... ;)
:D
I like this very much Ulco.Looks sweet.
Works really well Ulco. :)
Nice. Like the way the man's head and torso echo the shape of the rocks, or do the rocks echo the shape of the man ?
I hope rocks like that are legal where you live :)
Cool,I like it.
very cool. Love these rocks for the most part.
What happened at the top of the spire the man is standing on? Looks like you tried to hide it with the tree, but I am curious what is the cause.
Also, the red just below that, made me think that there should be a cave style painting there!

I'm all eyes...hee hee hee
You know, Michael, I was thinking exactly the same as you about the cave painting. Seriously. The bulging top is a bit lower poly due to the lopoliness of that particular lobe in the mesh. I think. I have to experiment with higher density and see what that does to the map, in relation to the size of the final map (which is small in this case).

Playing about with this with varying results. I found a few of those coloured maps on google and in Photoshop made them 32 bit and saved as both .exr and .tif. About 2 M from the .exr but 20 something M for the .tif, but I'm going with it as that's way more info and it seems to work O K. Will post a test render when I complete one.
Has anyone tried Normal maps?
Pretty cool!
I did another shape in Mudbox yesterday, and posted the 32-bit file in file sharing. So grab it and test it out. Here's what I made of it with some strata and displacements.
Looks great. Interesting thread!!

My hero...thanks Ulco...
Great!
I like the first one a bit more, because the haze seemes more relistic in that scene to me. But both are cool!

This is a cool way to model terrain but I am having a problem, likely through not knowing what I'm doing yet, but any ideas on why I'm getting isolated(to only this spot it seems) tearing in the vector displacement?
What do you mean by tearing? Your camera isn't under surface, by any chance? The map can be blown up if you set displacement too high, it's all in some kind of proportion. With 500m and displacement 1 it works, but if you reduce the area to 5m displacement should also be reduced.
Well I started fresh and got a scene to render, set it up for an overnight render and it was maybe 20% done in 6:30. Does that seem long on a 1280x720, D .6 AA 4 ? Does using Vector Displacement slow TG 3 down?

Looking back on that .tgd I noticed I'd sized the image map to 2048x2048. Likely that was my error. Thanks for the input
6+ hours for only 20% of such small a render is very long. Depends on your machine of course. My i7 turned the last 2 images out in half an hour each, detail 0.7, AA6. I don't think it really slows the rendering. Vey small additional displacements do.

Thanks man, guess it's a sick old dual core AMD that's draggin me down...
Anyone try this with a Lake? Here's my quick n dirty test. I've added the .tgd as if you dl'd the map from Dune, that's the only image in the pic.

These images are special!
Added the same vdisp setup to this scene; water without water shader ;)
That is a nice one :)

Awesome, guess that cuts render time a bit as well. Love the pier ripples...."without water" how was the transparency done then Ulco
There is no transparency 8)

D'oh...reflective shader...heh heh heh...thanks for the virtual slap up the side of my head ::)
We've seen you come up with something similar to this on a few past occasions; very nice.
Here's one I tried with Ulco's map on Cube a flattened a lot proportional to the width. I warped the map previous to entering the VDisp shader and found you cam get slight overhang on the waves by + or - on the X...I used -2. clip attached. If using it on a cube the map should have the same coords as the cube. The render has a close up of the waves and the shack is moved because close up i noticed rock in wall syndrome.
