Texture bright dots on terrain

[YouGroove]

hi

 

 

I choose a texture on terrain, and in the editor it display visible bright dots.

 

 

Textures on terrain should be equal as texture used.

Unity test with same texture : there is not dots problem

 

The texture can be found here to test :

creating and adding a normal map to the layer makes those go away

Can't look at this without having the actual texture.

Okay, the problem was the auto-generated normal map that gets created if no normal texture is present was getting the last pixel skipped when setting the pixel data:

		//Create default normal
	texture_defaultnormal = Texture::Create(64,64,Texture::RGBA);//Texture::Load("Materials/Common/normal.tex");
	Bank* data = Bank::Create(64*64*4);
	for (int i = 0; i < data->GetSize()/4-1; ++i) // The -1 is the culprit!!!
	{
		data->PokeByte(i*4+0, 127);
		data->PokeByte(i*4+1, 127);
		data->PokeByte(i*4+2, 255);
		data->PokeByte(i*4+3, 255);
	}
	texture_defaultnormal->SetPixels(data->buf);
	data->Release();
	texture_defaultnormal->BuildMipmaps();
