[SOLVED] Cannot paint height or texture with terrain editor

[Killer.Penguin]

We're having a problem with Terrain Editor. While we could paint holes fine, we cannot paint height map or diffuse map on our terrain at all. We have tried to change to different modes and using different parameters but nothing seems to work.

 

We tried everything we could think of, but we still see no result. Can anyone give us extra pointers?

 

best,

 

ps. And yes, we hold down the alt button and painted with left mouse...

Here's the steps we used to test the terrain editor.

 

- create a new terrain from the terrain icon with 1024x1024.

 

- click edit terrain button from the node window.

 

- try to paint with alt holding down in various mode. Nothing happened except the hole painting mode.

 

We tried this in Mac SDK and the hole painting doesn't even work...

Hi,

 

Brushes won't work if no texture is assigned to terrain.
Try to import height map using Nodes -> Terrain -> Heights -> Import, then create or import Diffuse, Normal and Mask textures.

For more details you can use these articles:

Thanks!

Will be fixed in the next SDK update.

Well actually, I tried importing in Heightmap and Diffuse map with various type of image files too. They worked great, but I just can't paint or edit them...

Hi,

Could you please answer the following questions to clearify the situation:

 - Did you try to modify the terrain from object/terrain_00 sample?

 - Could you export the height map from object/terrain_00 sample and import it to the new terrain: Heights and Holes brushes should work correctly, is it so?
 

Here you can find information about exporting height map from sample.

 

 

Thanks!

Ok, exporting and re-importing the same DDS height map fixed the problem for us.

 

:)

 

Just for ref, what's the DDS format do you use for terrain Height map and what kind? I can't use PSD Nvidia plugin to export the correct (128*x+1, 128*y+1) size.

DDS R16 encoding is:

dwFlags = DDPF_LUMINANCE

dwRGBBitCount = 16

dwRBitMask = 0x0000ffff

 

You can use PNG file format.
