[SOLVED] Tiles of TerrainGlobal dissappear

[Amerio.Stephane]

Hello,

Under some view angle/position, some tiles of a TerrainGlobal simply dissappear:

Nothing fancy about the terrain, just created with Landscape with DTED2, only one LOD. The tile appears and disappears depending on the viewer position and direction.

Test scene attached (bin, core, textures removed for size consideration)

Thanks for your help.

Hello Stephan,

we've fixed this issue, fix will be included in the upcoming 2.7 release.

Actually you can modify one shader file to fix this right now.

• Open /data/core/shaders/common/double_trigonometry.h
• Find these strings:

double dlength(double2 x) { return drcp(drsqrt(ddot(x, x))); }
double dlength(double3 x) { return drcp(drsqrt(ddot(x, x))); }

• Replace them with this

double dlength(double2 x) { return dsqrt(ddot(x, x)); }
double dlength(double3 x) { return dsqrt(ddot(x, x)); }

This is great news!

But I couldn't find this file. There is no shaders folders in the data/core of my projects.

It's in the sdk folder (..\sdks\sim_windows_2.6.1.1\data\)
