Week 25; It's the Final Countdown

Well, I didn't promise anything about song lyrics!

At least this weeks weak reference actually has some meaning behind it. Writing this blog now we've just broken up for the Easter holidays, meaning we only have 2 weeks left after this before our major hand-in. This includes the zombified pick-up truck, along with our extended writing piece, and a presentation due sometime when we get back from the Easter within the first week. The year is coming close do an end and it's getting really quite scary to think I've already completed my first year of teaching!

Anyhow, lets get onto what I did this week. For the most part; texturing. Lots and lots of it. So as I've covered before I have been using substance designer to create my PBR textures. I've been able to work out how to use the mesh to create maps like world space normals which essentially tell where the verts are pointing (from what I can understand from it), so it can apply wear and tear to certain parts of the mesh which would have more tear than others, or functions like bottom to top dirt.

Albedo
Normal

Metalic
I think this has gone quite well, I've really enjoyed the process of procedural generated textures and really believe this has got to be the way forward, since you can create a material and re-use it on a different mesh to have vastly different results. The interface did take a bit of getting used to but I did get there in the end and created my final asset!

The only problem I had was putting it into UE4 for the final beauty shots... UE4 as an engine doesn't support metallic or roughness maps, the format that Substance Designer uses. So I had to essentially faff around with trying to convert them into specular and gloss maps, which are still completely different to metallic and roughness maps. I'm going to be honest and I don't quite understand how I managed to make it work in UE4 but it does to a degree (apart from the chrome on the hub caps not showing up correctly).

I'll leave you with the beauty shots and I'll see you after Easter!
