The only time textures would update was through the file picker. Once uv coordinates were used, disabling them didn't have any effect because the vertex array didn't invalidate the corresponding buffer array. When shouldUpdate is true, the light source needs to know as well, otherwise it will set the ___location at 0,0. Textures were fixed by creating a member variable that holds the file name of the texture used in the last model rendering. Instead of invalidating buffer arrays it is much simpler to define a default uv coordinate set for the case when no un is specified. if a texture is not present then the values of uv will not be used. If there is a texture it must be a minimum of 1 pixel in size. So we choose the uv coordinates so that every vertex gets assigned the color at the 0,0 coordinate of the texture. When shouldUpdate is on, we also turn shouldUpdateLightSource on. Also included are some formatting changes that are purely aesthetical.

No problem, I'll take a look at it now. |
