Hi There,

Thanks for replying,

Well initially the textures weren't rendering properly (I could get the bumpmap with no texture (that blue screenshot) or the regular texture without bumpmap but not both) I have since found that this was a problem with setting the textures to the right numbers, which brings me to my current problem:

gl.glActiveTexture(GL2.GL_TEXTURE1);
                        texture.enable(gl);
                        texture.bind(gl);
                        setUniform1i(gl,shaderID,"colorMap",texture.getTextureObject(gl));
                        texture.disable(gl);

gl.glActiveTexture(GL2.GL_TEXTURE2);
                        normalMap.enable(gl);
                        normalMap.bind(gl);
                        setUniform1i(gl,shaderID,"normalMap",normalMap.getTextureObject(gl));
                        normalMap.disable(gl);


This works great, and I now get a bump-mapped colour textured model. However the new problem arises when I try to draw numerous objects, as they all override GL_TEXTURE1 and GL_TEXTURE2.

EDIT: For example, the skybox I am rendering now renders the same texture as the spaceship, when obviously I want it to render its own texture.

How would I go about making this implementation work for multiple objects? Something to do with GenTextures perhaps?

Sorry if I sound vague, my brain is somewhat confused at this point.
