His guys, I want to ask you guys about dealing with terrain and heightmap files. I wonder to know If we have any tools or software to open and edit terrain and heightmap. The terrain file was written by XML structure and the heighmap show up binary code. So I want to open and edit them because some of my Scene map terrain texture was not correct like the ground showed the square shape in their edges. If you guys have any suggestions, just shout It out to me. Thank you alot.

Re: How to deal with terrain and Heightmap?
Hello,
There is OGITOR: https://github.com/OGRECave/ogitor
But I'm not sure if you can open a heightmap that already exist.
What is the problem you are having? Do you have a screenshot?

Re: How to deal with terrain and Heightmap?
As you can see how the terrain texture is. It still show the edges so pointy. It does not look a real terrain. So I want to make It smoother and look realistic.
The second thing is the background that clip out objects like those images below :
This one is the full objects:
This one was clip out the objects:
That means the camera was clip out the objects far distance.
So I want to remove that background or make It turn into transparent.
And how can I install and run the ogitor.

I'm not sure how this is being done in this game but what you want here is what is called Alpha Splatting.
The idea is to mix different textures using alpha blending.

I don't know why this is happening, perhaps the developers have put the background on a small sphere that is clipping the geometry.
This might have been on purpose to reduce the amount of geometry thinking of slow GPUs and they mask this effect with the fog.
And how can I install and run the ogitor.
You can download the binaries from here:

Re: How to deal with terrain and Heightmap?
No, you have to download the binaries from the site and run them.
It is a visual editor.

Re: How to deal with terrain and Heightmap?
Thanks, so one more thing I wonder to know. In the scene, It has Environment, then I figured out that my Scene above has the background that clipping out the objects was inherrit the color of the ambient in environment function. So in the new Ogre model source, do we have a function of environment like that?

Re: How to deal with terrain and Heightmap?
Following from above, i've had trouble building Ogitor with my Ogre 13.5.2 installation.
I've downloaded the Ogitor source via git/clone, and configured with cmake-gui. The build starts to compile but stops with an error at CameraEditor.cpp.
If anyone has ideas that would be appreciated.

Re: How to deal with terrain and Heightmap?
the camera API was refactored and ogitor probably wasn't ported over. as far as i recall, ogitor needs to make these calls on the Ogre::SceneNode* instead of on the Ogre::Camera. i believe enabling "OGRE_NODELESS_POSITIONING" in cmake when building Ogre will also enable the old behavior.

Re: How to deal with terrain and Heightmap?
Thanks loath. This helped. I reinstalled Ogre with "OGRE_NODELESS_POSITIONING" enabled. This got me past the camera issue at 10%. However, the build now fails at 50% with a plugin and AngelScriptInterpreter.cpp.
I couldn't find an easy way to disable this plugin (or if it is required). Unless there's an obvious fix that I've missed, I think I'll hold off on Ogitor for now. Maybe I'll try again with an earlier Ogre release with static libraries. Sorry for hijacking this thread.
