Strata2 default ProceduralTerrain rendering error with holes? ----------------------------------------------------------------------------------- I have rendered the Strata2 Procedural terrain included in the Vue 8.4 xStream default collection. - But the problem is that it appear strange holes in the rendering on the terraces and plateaus at a little bit altitude. I thinked that these are water reflections of the material; thus I have resetted the terrain material; but the problem is not relative to the material. The holes appear also after Reset Material operation.

Please see the attached rendering!
Please help me!
Many thanks in advance!

have you enabled clipping on the terrain editor screen?

 A cleaved head no longer plots.

I tried some settings: it appears that the problem is relative to the "Force Extension" value in the main panel of terrain editor of the procedural terrain.
I am not sure...but this is a issue that appears with all the terrains with Force extension applied!

Whoow!
With the clipping at Max value=86.12 instead of 100 the issue disappear!
But with clipping OFF, at Max=100, the force extension value generate the problem.
Why?

I tried all kinds of displacement/normal/clipping/forced extension settings with Strata 4 (which looks like your rendered terrain.  My Strata 2 is more sawtooth blade-shaped).  But I could not get the hole on top.  I'm using VueInf 8.0 and not 8.4.  Is your render from Vue or from another program?

My render isi nternal from Vue not from 3DSMax+xStream.
I installed Vue 8.4 Update xStream because it is a lot of updates that prevent crashes.
Help!

Another rendering: Strata4 with Force Extension applied: the hole is clearly visible without Clipping-Max!

I "Cancelled Last Update" command, removed 8.4 Update and leaved just Vue 8.10-04 Build 49622.
But the problem persists!
Help!

I'm using 8.0 build 47776 and was not able to get Force Extension to do what happens to you.  Maybe you bought 8.1 and can't download any 8.0 builds.

I rendered with Vue 8.4 Update xStream in 3DSMax 2010+SP1, with ForceExtension turned ON and Clipping Max turned OFF.
The hole artifacts are also visible!
Only with Clipping Max turned ON the hole disappear.
This is a BUG?
Help!

Ok.  I goofed.

I was in the Material Editor, playing with Force Extension.  So of course I was getting different results.  In the Terrain Editor, if I turn on Force Extension and drag the value down, I get holes in my mountain tops regardless of the clipping used.  This is still with Strata 4, I'm using.

Ok.  My question is:  What value is your Force Extension set to and what are you hoping to achieve with Force Extension enabled?

Strata4: my value of ForceExtension in TerrainEditor is 1.0.
I hope to achieve a good "cut" result of the strata mountains, similar to terraces or plateaus. This because I want also export my terrain as mesh in 3dsMax, by baking polygons in Vue, and use this mesh to create a car simulation in Max with CraftDirectorStudio plugin.
I need to drive the car over the top of the flat mountains terraces, without holes.
If I make the baking of polygons and use the clipping-Max method instead of ForceExtension, in TerrainEditor, I can't achieve the "cut" of the mountains, because the mountains extend to all the height after exporting them.

I should also change something in the MaterialEditor?

Check page 402 of the manual.  It goes into detail about strata fractal settings there.

I checked page 402 trough 405, about Strata Node, but I haven't understood at all what parameter should I tweak!

I tried to change all the settings, but I have successfully changed other stratification properties, without achieve the result of filling the plateau holes!
The holes don't disappear at all!

Help!

The manual does not recommend using force extension.  So what does the terrain look like in 3DS Max after baking?  Maybe the strata cutting can be added using that program?

Right now I'm playing with the "Recursive/Strata" filter on a terrain fractal in the terrain function editor.  Instead of using one of Vue's strata terrains, you can create a custom one with this filter. 

Have you played with these settings yet?  Pretty cool.
