It seems like I've managed to port textures from the old model to a new one, with all texture issues as well. At least they are fixable. This can be seen as proof of concept because one of the main concerns that could make this remake impossible - textures. Now knowing that it is possible, I can continue work on it.
Can say I'm halfway through finishing this edit, but this doesn't mean I'll finish it soon. There is still one HUGE step - rigging, and you may remember how I struggled with it when I was working on the second model remake (R-# posts).
About proportions - I'll adjust them with the rig. One of the advantages of making such a "base model" is that you can adjust it however you like.
Meanwhile, I'm rendering A15 but don't wait for a release soon. It seems like I've done something wrong and now my GPU is struggling to render it. It takes A LOT of time to render. Thus I need multiple renders because I always find something missing from the render, so it will take a week or more. Welp...
