Baking the results into a new format will lead to less overhead during the loading and execution of my game, which is what every game developer wants at the end of the day. I'm actually kind of glad that I discovered all of this when I did, because this is a headache that needs to be dealt with sooner rather than later. I will also be choosing your answer if you can just do me a small favor and basically sum up what I have just said. | |
| Jun 14, 2017 at 7:30 | comment | added | Krythic | I've been doing a lot of reading...seriously, I don't think I can express just how much I have been doing. It's become painfully obvious that a Wavefront Model does not inherently support VBO's out-of-the-box. According to the sources that I have seen, I will need to load in the data and modify it so that the indices line up with the Vertices array, the Normals array, and the texture array. This means that I will have to be duplicating index locations in order to obtain a congruent array of indices, which is properly aligned. Because of this I will also take the extra step of declaring my own | |
