Week 18 - Sketchfab, Emission and Opacity

What Have I Learned This Week?

Today we learned about using Sketchfab, an online website that can allow you to get a live render of a model using all the acquired maps by exporting them all from Quixel Mixer. 


On Sketchfab these maps can be adjusted appropriately, as well as lighting and adding a scene to the render. However, a lot is limited on a free account.

Emissions

We also learned about creating emissions. Emissions are used when you want an area to glow or have a brighter appearance. These maps can be made on Quixel Mixer using solid layers and applying the colours appropriately. On the top solid layer, I applied a noise mask that created a contrasting glow. One mistake I made on my map is that the base layer should be black in colour, but this could easily be fixed on Photoshop. These emission maps can also be applied to specific Material ID sections.

Opacity

Opacity maps are made similar to emission maps. Here, opacity maps are made with a base white layer and a grey solid layer with Material IDs applied to their desired area. Opacity is used for transparency of areas where is it wanted.

Week 17 - PBR Metalness (Learning Quixel Mixer)

  Week 17 - PBR Metalness (Learning Quixel Mixer) What have I Learned This Week? This week, we've begun to start fully texturing our meshes with PBR software. I chose to start familiarising myself with Quixel Mixer. For this, I used my Crimson Model as I had all the maps prepared. Most PBR software with produce a PBR Metalness. PBR Metalness is a map that contains the metalness information of a mesh and will also contain the albedo. An alternative is PBR specular workflow, the high-end 3D industry standard that contains the information of metalness as well as reflectivity  I started by preparing the Base Layer of the weapon. Albedo refers to the overall brightness of a model, the whiter the Albedo the more light reflects and produces more brightness. Metalness refers to the metal texture of a mesh or layer. If a mesh has a metal texture, the Metalness will be coloured white. Roughness refers to the glossiness of the texture. If the Roughness is black when the texture will appe...

Week 21 Hybrid Weapon Asset Production

  Week 21: Hybrid Weapon Asset Production 3D Artists In The Industry Over the course of this year, I have been looking into a range of 3D artists and their development into 3D assets as well as environments. In term 1, I looked at Patrick Sutton and Tyler Smith, two 3D artists who work on 3D assets and Environments respectively, as well as the range of programmes they both use. Moving on from term 1, I have started to become more comfortable with the programmes I use in 3D production which now allows me to evaluate and study 3D artists in more detail and understanding. (Cramer 2020) A new artist I started to follow was Andreas Cramer as recently at the time I spent a lot it practising with gun models to develop my Maya skills. Cramer first started the model in Blender as a way of practising this program as he was new to it, but inevitably went back to Maya. It's no surprise a model like this would be much harder in Blender as Maya is used for more Hard Surface and rigid models such...
