Terrain Layers on Intel GPU

[toddgrayson]

It looks like the terrain layers don't work properly when using an Intel GPU. Note: The first layer shows fine, but any additional layers won't paint.

 

Note: I tested on a Microsoft Surface Pro 2 with an Intel 4400 GPU

It's working fine with these drivers:

Unfortunately those are desktop drivers. Even so I tried them and they installed on the Surface Pro 2, but they didn't work.

 

Note: There may be differences between the desktop processor and the mobile/laptop ones

I was able to resolve this by adding the following variables back into the Shaders\Edito\TerrainTools\paint.shader

 

uniform int slotbit;

uniform int channel;

Those variables are not used in the shader at all though.

Oops, sorry. I just commented out the top shader and uncommented the code code below it and it worked. When i looked it seemed that the only difference was the two variables i mentioned. After a closer examination it seems that it wasn't those at all but rather it was the texture() instead of the texture2d() that resolved the issue. I did some testes and it works great using texture.

 

//vec4 current = texture2D(texture0,ex_texcoords0);

vec4 current = texture(texture0,ex_texcoords0);

 

The uncommented one works.
