Share your displacement tests with the world !
Here are my first shots.
(I'm lazy so I only used the preview scene)

Why is the base of the test scene not displaced at all?

Good idea on the thread, rather than filling up the 1.1.1 thread with em
And I noticed the base on mine weren't getting displaced either
Not sure what I'm doing wrong, it's definitely getting subdivided..

The base is not displaced because it's not subdivided.
I keep it this way to save some memory, waiting for the x64 release (wich is really needed when using subdivision+displacement).
@zsouthboy : Have you placed the subdivision tags to both the sphere and the base meshes ? ("preview_sphere" and "preview_base")

Man I like the grassy one. But you got me worried about memory consumption. It would be really good to be able to use this over large areas.

the stone-one looks awesome...i missed the whole news about displacement stuff - is this similar to use of disp mod in blender (BW disp map + hi poly mesh)? is this more memorywise than blender-like technique?

Yep, checked and double checked, and I see indigo subdividing preview_sphere and preview_base.

Just copied from the 1.1.1 thread

new tries, textures were "borrowed" from maxwell's materials website.
@zsouthboy : You're right, I tried to displace the base too, and it didn't work. Is it a bug ?
@Alex : excellent !
@BbB : I guess high memory usage is the price to pay. I will try a large scale test tomorrow.

that last one looks pretty cheesy

Wow! How long did you guys let these tests render (and on what kind of systems)? They look amazing!

Get yourself a quadcore and you'll wonder what you did without it!

One more basic test (jeez I could play with that build forever). Will try some tests on more consistent stuff tomorrow.
@cookieofdoom : each images cooked for about 20mn on a core2duo

This is my first attemp on displacement.. Although scale of the object was correct (or at least I've done the usual procedures to get into scale) only when I bumped b up to ten I got to see the desired displacement, although the amount I was thinking was on the centimeters rather on meters...
The ball is 200mm
Code: Select all
<material>
<name>Rocks</name>
<phong>
<ior>1.8246545641235646</ior>
<diffuse_albedo_spectrum>
<rgb>
<rgb>0.8 0.8 0.8</rgb>
<gamma>2.2</gamma>
</rgb>
</diffuse_albedo_spectrum>
<exponent>122.5</exponent>
<albedo_texture>
<uv_set>default</uv_set>
<path>tex\ROCAS.jpg</path>
<exponent>2.2</exponent>
</albedo_texture>
<displacement_map>
<uv_set>default</uv_set>
<path>tex\ROCAS_displace.jpg</path>
<b>10</b>
<exponent>2.2</exponent>
</displacement_map>
</phong>
</material>
on a side note is interesting to find that the greater the bump the greater the impact the max_num_subdivisions has, and the bigger the detail

aint that the truth ! My quad is about the first machine I've had that can keep up with my demand of activity
