Re: [osg-users] Passing multiple textures in glsl

Hi, I tried add these lines into my code: osg::Texture2DArray* tileImgLay; tileImgLay = new osg::Texture2DArray; tileImgLay-setTextureSize(128, 128, 2); tileImgLay-setUseHardwareMipMapGeneration(false); tileImgLay-setImage(0,

Hi, I did not get any compiler error. The application runs successfully. However, the texture did not seem to be loaded into the shader code. The image rendered as black in color. As the lines, Where should I add them? #version 120 #extension GL_EXT_gpu_shader4 : enable #extension

Re: [osg-users] Passing multiple textures in glsl

Hi Linda, Your code looks correct to me. Your shader does the texture lookup at 0,0,0 coord is there a chance that your test1.bmp picture is black in the corner ? Or its res differs than 128x128 so loading them does not work or leaves some empty space ?. You may try to run the example code

Hi, the OSG 3rd Party Package for VS9 provides CURL and GDAL. So download that package, point your folders to the correct subfolder (x86/lib|include or x64/lib|include) and it should work. Thank you! Cheers, Torben -- Read this topic online here:
