Cromwell Tank
Cromwell WW2 Tank made in Unreal Engine 4 using Environment workflow.
Model was done in Midpoly workflow, there is no Highpoly or Normal Bake, no Unique textures besides RGBA masks.
Point of this project was to create a Vehicle with texel density of 32 using tillable/reusable, trim textures and and unique RGBA masks.
To achieve this result I've made a shader in Unreal Engine which layers tillable textures by using RGBA masks.
Hope you like it :D
I hope this is gonna make sense
Asset uses 4k tileable and trim textures in order to achieve texel density of 32 pixels per centimeter
First UV set is used for Tileable textures
Second UV set is used for RGBA masks which tells the shader how to combine tillable textures
Third UVset is used for Trim textures
Trim textures are used for bolts and smaller parts of the tank
Example of the RGBA weathering masks which are done in substance painter with texel density of 2
Additional RGBA mask for camouflage and tint
Example of the RGBA channels in Painter
Layering tileable textures in engine using only masks gives us this result
Layering tileable textures in engine using masks which are divided with the height information of the tillable textures gives us this result
Example of the Height map which are stored in the Alpha channel of each texture
Logic in upscaling lowres RGBA masks by dividing them with Height maps in engine
Example of what shader is doing shown in Painter
Example of applying textures using vert paint in engine
